Renting vs. Buying in San Francisco

One of the most common questions I hear from San Francisco renters is:

Does buying a home here still make financial sense?

The answer is not automatically yes.

In fact, depending on your rent, the property you are considering, your financing, your expected holding period and what San Francisco real estate does over the next decade, renting can absolutely be the better financial decision.

That is particularly true for someone sitting in a desirable rent-controlled apartment at a substantially below-market rent.

But the reverse can also be true.

Over a ten-year period, ownership introduces several things that renting does not:

Principal paydown.

Potential appreciation.

Leverage on the appreciation of the entire property.

Potential tax benefits.

More control over your housing.

And an asset that can eventually be sold, refinanced or potentially converted into a rental.

So instead of asking:

“Is renting cheaper than buying?”

I think the better question is:

“Where will I be financially ten years from now under each scenario?”

That produces a much more interesting answer.

Let's Run a Real San Francisco Example

Consider a buyer deciding between renting a good two-bedroom apartment and purchasing a $1.5 million San Francisco condominium.

That is a relevant price point. San Francisco's overall median home sale price was approximately $1.59 million for the three months ending August 2026.

Here is the hypothetical purchase:

Purchase price: $1,500,000

Down payment: 20%, or $300,000

Mortgage: $1,200,000

Mortgage rate: 7.03%

30-year fixed principal and interest: approximately $8,008 per month

Then add:

Property taxes: approximately $1,478 per month initially

HOA dues: $1,000 per month

Condo insurance: approximately $150 per month

Interior maintenance reserve: $300 per month

That puts the initial economic carrying cost at roughly:

$10,900 per month.

And that is before considering utilities or expenses that would generally exist whether you rent or own.

Now compare that with renting.

As of September 2026, Zillow reported an average asking rent of approximately $5,661 for a two-bedroom San Francisco apartment or condominium.

Suddenly the comparison looks extreme:

Rent: roughly $5,700

versus

Own: roughly $10,900

On a monthly cash-flow basis, renting wins easily.

But that still isn't the full analysis.

Why Comparing $5,700 of Rent to $10,900 of Ownership Is Misleading

Your entire mortgage payment is not an expense.

Part of it pays interest.

Part of it pays down principal.

That principal becomes equity.

Using our $1.2 million mortgage example, over the first ten years the owner would pay down approximately:

$170,000 of mortgage principal.

The owner would still owe approximately:

$1.03 million after ten years.

That is one reason ownership needs to be evaluated differently from rent.

Rent is essentially consumed.

Principal repayment is a transfer from cash into home equity.

But we also need to be fair to the renter.

The renter has an enormous financial advantage at the beginning:

They still have the $300,000 down payment.

And they can invest it.

That opportunity cost is one of the most frequently ignored parts of the rent-versus-buy debate.

The Renter Gets to Invest the $300,000

Suppose the renter does not spend the down payment.

Instead, they invest the approximately $300,000 that would otherwise have gone into the condominium.

Let's also assume roughly $15,000 of purchasing closing costs that the renter avoids.

That gives the renter approximately:

$315,000 invested on day one.

Now assume that investment earns an average 5% annually over the next decade.

The renter also invests the difference between renting and owning every month.

That is critical.

If renting costs approximately $5,700 and owning initially costs close to $10,900, the disciplined renter has more than $5,000 per month available initially to invest elsewhere.

Of course, that advantage narrows over time as rent rises.

But it is still substantial.

Our 10-Year Assumptions

To make the comparison more realistic, let's use these assumptions:

Purchase price: $1.5 million

Down payment: $300,000

Mortgage: $1.2 million

Mortgage rate: 7.03%

Starting HOA: $1,000/month

HOA inflation: 3% annually

Insurance: $150/month initially

Interior maintenance reserve: $300/month initially

Property tax: approximately 1.18% initially

Rent: $5,661/month initially

Rent growth: 3% annually

Investment return for renter: 5% annually

Purchase closing costs: approximately 1%

Selling costs after ten years: approximately 5%

For property taxes, I am using roughly San Francisco's current secured-property-tax rate as a starting point. San Francisco reports a 1.18268325% secured property-tax rate for fiscal year 2025–26.

These are assumptions, not predictions.

And that distinction matters enormously.

Change appreciation from 3% to 5%, and the result changes substantially.

Change the renter's starting rent from $5,700 to $7,500, and the result changes again.

That is exactly why blanket statements about renting versus buying are not particularly useful.

Scenario One: San Francisco Appreciates 3% Per Year

Suppose the $1.5 million condo appreciates at an average of 3% annually.

After ten years, it would be worth approximately:

$2.02 million.

That sounds excellent.

The owner bought at $1.5 million and now owns something worth a little over $2 million.

But we still need to subtract:

The remaining mortgage.

And the cost of eventually selling.

At an assumed 5% selling cost, the owner's estimated proceeds after paying off the mortgage would be approximately:

$885,000.

That is substantial equity.

But now look at the renter.

If our renter invested the initial $315,000 plus the monthly difference between renting and owning at a 5% annual return, the renter's investment account would grow to approximately:

$1.26 million after ten years.

Under these particular assumptions:

Renting wins financially.

Not because buying was a disaster.

Far from it.

The owner still accumulated nearly $900,000 in net home equity.

The renter simply accumulated more wealth because the monthly cost difference was so large and because the renter's original capital remained invested.

This is the point most simplistic rent-versus-buy calculators miss.

Scenario Two: San Francisco Appreciates 4% Per Year

Now assume the same condo appreciates 4% annually.

After ten years:

Estimated property value: approximately $2.22 million.

After estimated selling expenses and paying off the remaining mortgage:

Estimated owner equity: approximately $1.08 million.

The renter in our example still ends with approximately:

$1.26 million invested.

Renting is still somewhat ahead financially.

But the gap has narrowed dramatically.

This is where the analysis begins to get interesting.

Scenario Three: San Francisco Appreciates 5% Per Year

Now assume average appreciation of 5%.

After ten years, the $1.5 million property would be worth approximately:

$2.44 million.

After estimated selling expenses and paying off the mortgage:

Estimated net owner equity: approximately $1.29 million.

The renter's estimated investment account:

Approximately $1.26 million.

Now ownership has moved slightly ahead.

The difference is not enormous, but the result has flipped.

That gives us an important number.

In This Example, Break-Even Appreciation Is Roughly 4.9%

Using these assumptions and excluding individualized income-tax benefits, the condominium would need to appreciate at approximately:

4.9% per year over ten years

for owning and renting to produce roughly equivalent ending wealth.

That is not a prediction that San Francisco condos will appreciate 4.9%.

It is simply the hurdle rate created by this particular combination of:

Purchase price.

Mortgage rate.

Rent.

HOA dues.

Down payment.

Investment return.

And transaction costs.

Change any of those inputs, and the break-even point moves.

Here Is What the Ten-Year Comparison Looks Like

This is why I do not tell sophisticated buyers:

“Real estate always wins in the long run.”

Sometimes it does.

Sometimes the renter wins.

The answer depends heavily on what you pay for rent today and what happens to the property over your holding period.

Rent Control Can Completely Change the Equation

Now imagine the renter is not paying $5,661.

Instead, they have occupied a rent-controlled apartment for years and pay:

$4,000 per month.

And assume their rent rises by only about 1.5% annually for purposes of this hypothetical comparison.

That is an extremely valuable financial asset.

It may not appear on a balance sheet, but economically it has value.

Under that scenario, if the renter invests the down payment and the monthly savings, they could end our ten-year example with roughly:

$1.59 million in invested assets.

For the owner to end up in approximately the same position, our $1.5 million property would need to appreciate at roughly:

6.3% annually for ten years.

That is a significantly higher hurdle.

This is why telling someone with a $4,000 rent-controlled apartment that buying is "obviously smarter because you're building equity" is incomplete financial advice.

That renter may have an extraordinarily valuable housing situation.

Now Consider the Person Paying $7,500 in Rent

The equation changes again.

Perhaps you are renting a large, renovated two-bedroom or three-bedroom home for:

$7,500 per month.

Now the difference between renting and owning is much smaller.

Under the same assumptions, the renter's estimated investment portfolio after ten years drops to approximately:

$940,000.

The appreciation required for ownership to catch up falls to only about:

3.3% annually.

Suddenly buying becomes considerably more compelling.

That is why your current rent is one of the most important inputs in the entire calculation.

The Rent Number Matters More Than People Realize

Using the same $1.5 million purchase:

If you pay approximately $4,000 in rent

Ownership needs roughly 6.3% annual appreciation to economically catch the renter in our model.

If you pay approximately $5,661 in rent

Ownership needs roughly 4.9% annual appreciation.

If you pay approximately $6,500 in rent

Ownership needs roughly 4.2% annual appreciation.

If you pay approximately $7,500 in rent

Ownership needs only roughly 3.3% annual appreciation.

That is a massive spread.

There is no universal rent-versus-buy answer because renters are not starting from the same place.

But We Have Not Included Tax Benefits Yet

This is where the calculation gets more individualized.

Mortgage interest may be deductible for buyers who itemize, subject to federal limitations.

For qualifying mortgage debt incurred after December 15, 2017, federal rules generally limit the mortgage-interest deduction to interest attributable to the first $750,000 of acquisition debt for eligible taxpayers.

That matters in San Francisco because many mortgages substantially exceed $750,000.

Our hypothetical buyer has a $1.2 million mortgage.

That does not mean all of the mortgage interest is deductible.

Property-tax deductions are also subject to the federal SALT limitation.

For 2026, the IRS says the overall SALT deduction limit is $40,400, with the limit beginning to decrease for modified adjusted gross income above $505,000 and not falling below $10,000.

For a high-income San Francisco household, that phaseout can matter considerably.

Therefore, I would not put a generic "$2,000 per month tax savings" into a rent-versus-buy analysis and pretend it applies to everyone.

Your filing status.

Income.

Other deductions.

Mortgage size.

State income taxes.

Property taxes.

And whether you itemize

can materially change the tax benefit.

A CPA should ultimately model that portion.

But if ownership generates a meaningful after-tax benefit for you, it lowers the effective cost of owning and reduces the appreciation rate necessary for ownership to catch renting.

Leverage Is the Powerful Part of Real Estate

There is another reason relatively modest appreciation can produce substantial equity creation.

You are generally not earning appreciation only on your down payment.

You are earning appreciation on the entire property.

In our example, the buyer contributes $300,000 toward a $1.5 million home.

Suppose the property appreciates 5% in the first year.

That is:

$75,000 of appreciation.

Relative to the initial $300,000 down payment, that represents a 25% increase before considering transaction costs, financing costs, taxes or principal paydown.

Of course leverage works in both directions.

A 10% decline in property value is:

$150,000.

That would equal half of the original down payment.

Real estate leverage can accelerate wealth creation.

It can also magnify losses.

Sophisticated buyers should understand both.

Principal Paydown Is Slow at Today's Interest Rates

Another misconception is that a large part of your mortgage payment immediately builds equity.

At a 7.03% rate, that is not the case.

Our hypothetical $1.2 million mortgage requires approximately $8,008 per month of principal and interest.

But during the early years, most of that payment is interest.

Over ten years, the borrower pays approximately:

$791,000 in interest

and only about:

$170,000 in principal.

This does not make the mortgage a bad decision.

It simply means buyers need to understand where their money is actually going.

At today's rates, appreciation has a much larger impact on ten-year wealth creation than principal amortization.

The Mortgage Rate May Not Stay at 7%

This is another variable the static calculations cannot fully capture.

Our example assumes the buyer carries a 7.03% mortgage for the entire decade.

Reality may be different.

If rates eventually fall and the homeowner refinances to 5.5%, 5% or lower, the cost of ownership could decline materially.

But I would never recommend buying based on the assumption that:

“You can always refinance later.”

You may be able to.

You may not.

Rates may remain higher than expected.

Your financial situation could change.

The property's value could change.

The refinancing economics may not make sense.

I prefer to determine whether the purchase works with today's financing.

A future refinance should be upside.

Not the strategy required to make the purchase affordable.

HOA Dues Deserve More Scrutiny Than Buyers Give Them

With condominiums, HOA dues are often treated as if they are simply another annoying monthly expense.

That is too simplistic.

An HOA payment can cover some combination of:

Building insurance.

Water.

Garbage.

Exterior maintenance.

Roof reserves.

Elevator maintenance.

Staff.

Security.

Landscaping.

Common-area electricity.

Professional management.

Amenities.

And capital reserves.

A $1,000 monthly HOA could represent excellent value in one building and inadequate funding in another.

A $650 HOA could actually concern me more if the association is chronically underfunding reserves.

The correct question is not:

“Are the HOA dues high?”

It is:

“What am I receiving, and is this building being responsibly funded?”

Low HOA Dues Can Be a False Economy

Buyers love low dues.

Understandably.

But artificially low HOA dues can create deferred obligations.

If the association has not been reserving adequately for:

Roof replacement.

Exterior painting.

Waterproofing.

Elevators.

Windows.

Structural repairs.

Balconies.

Plumbing.

Or other major systems,

the eventual bill may arrive through a special assessment.

An HOA charging $700 per month and maintaining strong reserves can sometimes be financially healthier than one charging $450 and carrying almost no reserves.

When comparing renting with owning, potential assessments are part of the ownership risk.

Appreciation Is Not Uniform Across San Francisco

Another problem with generic rent-versus-buy calculators is the assumption that every San Francisco property appreciates at the same rate.

It does not.

A scarce single-family home in a highly desirable neighborhood may behave very differently from a condominium in a large building with many interchangeable units.

Appreciation can depend on:

Neighborhood.

Architecture.

Property type.

Views.

Parking.

Outdoor space.

Floor plan.

Building quality.

HOA health.

Monthly dues.

Supply of comparable properties.

And what buyers want ten years from now.

This is why the quality of the asset matters so much.

If you are going to own something for ten years, I am less interested in finding the cheapest property than I am in finding one with characteristics future buyers are also likely to value.

Transaction Costs Are the Enemy of Short Holding Periods

Buying and selling real estate is expensive.

There are acquisition costs.

Loan expenses.

Escrow.

Title.

Inspections.

Potential transfer-related expenses.

And eventually selling costs.

That creates a significant round trip.

This is one reason I become much more cautious when a buyer tells me:

“I may only be in San Francisco for two years.”

Could buying still work?

Yes.

A rapidly appreciating market could overcome the transaction costs.

But you are taking considerably more market risk.

At ten years, appreciation and principal paydown have substantially more time to absorb those costs.

At eighteen months, they may not.

Five Years Is Different From Ten Years

This is why I generally think about ownership in terms of a holding-period spectrum rather than a simple rent-versus-buy rule.

One to three years

Renting often deserves very serious consideration.

Flexibility has value and transaction costs are difficult to overcome.

Three to five years

The answer becomes much more property-specific.

Purchase price, appreciation and financing matter enormously.

Five to seven years

Ownership begins to become more compelling for many buyers, particularly when their existing rent is high.

Seven to ten-plus years

The compounding effects of appreciation and amortization have substantially more time to work.

But even over ten years, as our example shows, a renter with inexpensive housing and disciplined investing can outperform ownership.

Time helps ownership.

It does not guarantee victory.

The Biggest Assumption: Will the Renter Actually Invest the Difference?

This deserves its own section because financial models often assume perfect behavior.

The renter is theoretically investing:

The $300,000 down payment.

The avoided closing costs.

And thousands of dollars of monthly savings.

Every month.

For ten years.

If they actually do that, renting can be an excellent wealth-building strategy.

But many people do not.

The $300,000 slowly gets spent.

The $4,000 monthly difference becomes travel, restaurants, cars or lifestyle spending.

Ten years later, the homeowner has a $2 million asset and the renter has very little additional invested wealth.

That is not a flaw in renting.

It is a behavioral difference.

Forced savings is one of homeownership's underrated financial characteristics.

Every mortgage payment requires the borrower to put at least some money into the property.

For some people, that discipline is extremely valuable.

Buying Also Has a Consumption Component

Not every advantage of owning needs to appear in an investment spreadsheet.

You are also consuming housing.

Maybe ownership gives you:

A better home.

More space.

A backyard.

The ability to renovate.

A kitchen you actually want.

A dog without asking permission.

More permanence.

A neighborhood you plan to remain in.

The ability to design the home around your life.

And protection from having an owner decide to sell the property.

Those have economic value even if they are difficult to quantify.

Homeownership is partly an investment.

It is also a lifestyle purchase.

Pretending otherwise creates bad analysis.

Renting Has Lifestyle Value Too

The same is true of renting.

Renting can provide:

Mobility.

Less responsibility.

No surprise building assessments.

No need to finance major repairs.

Lower transaction costs.

The ability to change neighborhoods easily.

And substantially less capital tied up in housing.

For someone uncertain about career, relationship, family plans or how long they want to remain in San Francisco, that optionality can be extremely valuable.

Liquidity has value.

Flexibility has value.

Those belong in the analysis too.

The Right Question Is Not “Will My Home Go Up?”

Over a ten-year period, the more useful question is:

What return does this particular property need to generate for ownership to outperform my realistic alternative?

If you are paying $7,500 in rent, that hurdle may be relatively modest.

If you have a beautiful rent-controlled apartment for $3,500, the hurdle can be quite high.

If you are putting 50% down, the economics change.

If you can invest your capital at 8% instead of 5%, the economics change.

If you buy a condominium with $2,000 monthly HOA dues, the economics change.

If mortgage rates fall and you refinance, the economics change.

If your property substantially outperforms the broader condo market because it has exceptional characteristics, the economics change.

This is why I don't believe in answering the question with a slogan.

So: Rent or Buy in San Francisco?

Here is how I would think about it.

Renting deserves serious consideration if:

You have substantially below-market rent.

You are protected by rent control.

Your future in San Francisco is uncertain.

Buying would dramatically increase your monthly housing cost.

You value liquidity.

You are disciplined enough to invest the money you are not putting into a property.

Or the property available within your budget requires compromises you do not want to make.

Buying becomes increasingly compelling if:

Your current rent is already high.

You expect to remain in San Francisco for seven to ten years or longer.

You have sufficient liquidity after the down payment.

You can comfortably absorb the monthly payment.

You are buying a property with strong long-term fundamentals.

You value housing stability and control.

And you want exposure to San Francisco real estate as part of your long-term net worth.

The Bottom Line

Buying a home in San Francisco is not automatically smarter than renting.

And renting is not automatically "throwing money away."

Those are outdated ways of looking at the decision.

In a high-cost city, with mortgage rates around 7%, the financially correct answer can genuinely be:

Keep renting.

Particularly if you have a favorable rent-controlled apartment.

But a ten-year ownership period can produce substantial wealth when you combine:

Appreciation.

Leverage.

Principal paydown.

Potential tax benefits.

And the utility of owning the home itself.

The crucial point is that the answer depends on your alternative.

A renter paying $4,000 and a renter paying $7,500 are not making the same financial decision.

A buyer purchasing an exceptional property with durable characteristics is not making the same investment as someone buying a compromised unit simply because they feel pressure to own.

So before deciding whether you should rent or buy in San Francisco, run the actual numbers.

Not just:

Rent versus mortgage payment.

Run:

Your current rent.

Expected rent increases.

Purchase price.

Down payment.

Mortgage rate.

HOA dues.

Property taxes.

Insurance.

Maintenance.

Investment return.

Tax implications.

Likely holding period.

Transaction costs.

Potential appreciation.

And the opportunity cost of your capital.

Then ask one final question:

Which option leaves me with both the life and the balance sheet I want ten years from now?

That is the rent-versus-buy calculation that actually matters.

If you are considering buying a home or condominium in San Francisco and want to compare the economics against your current rental situation, I am happy to run through the numbers with you and look at the specific property you are considering.

Because in San Francisco, the answer is not always "buy."

Sometimes the financially sophisticated decision is to keep renting.

And sometimes the right property, held for the right amount of time, makes ownership the much better long-term decision.
