For homeowners preparing to purchase their next home, there’s a decision that often comes up:
Should I sell my current home, or keep it and turn it into a rental?
For some San Francisco Bay Area homeowners, keeping the property can be appealing. Maybe you have significant equity. Maybe you have a mortgage you don't want to give up. Or perhaps you like the idea of turning your current home into a long-term investment.
Historically, however, keeping the home could create another challenge:
Qualifying for the mortgage on the next property.
New Fannie Mae guidelines taking effect November 1, 2026 may provide additional flexibility for certain borrowers who want to convert their current primary residence into a rental.
But that doesn't automatically mean keeping the home is the right financial decision.
There are really two separate questions to answer:
Can you qualify to buy the next home while keeping this one?
And:
Does keeping this home as a rental make sense for your bigger financial picture?
When a homeowner moves out of a primary residence and converts it to a rental, the mortgage payment on that property can affect qualification for the next home.
Under Fannie Mae's updated guidelines, eligible borrowers may be able to use 75% of the property's market rent to help offset the monthly housing expense on the departing residence, subject to applicable requirements.
One important aspect of the change is that, in certain situations, the borrower may not need to already have a tenant and executed lease in place. An eligible appraisal or rent schedule may be used to establish market rent.
That could make a meaningful difference for someone who wants to purchase the next home before a tenant has moved into the current one.
Suppose the total monthly housing expense on your current home is $3,000.
An eligible appraisal indicates that the property's market rent is $4,000 per month.
Seventy-five percent of $4,000 is $3,000.
Depending on the borrower's circumstances and applicable guidelines, that rental income may be used to help offset the $3,000 monthly housing obligation when qualifying for the new mortgage.
That could make it easier for some homeowners to purchase their next home without having to sell the departing residence first.
But there are additional eligibility and reserve requirements, so this isn't a strategy that will work exactly the same way for every borrower.
This is where mortgage planning becomes important.
A lending guideline can tell us whether a particular financing strategy may be available.
It doesn't tell us whether converting your home into a rental is the right financial decision for you.
Before deciding to keep the property, there are several other questions worth considering.
Start with realistic cash flow.
What rent could the property reasonably generate?
Then look at the expenses associated with keeping it.
That may include:
A property generating $4,000 in monthly rent doesn't necessarily mean you're receiving $4,000 in monthly profit.
Understanding the difference between rental income and actual cash flow is an important part of the decision.
For some Bay Area homeowners, this may be one of the biggest considerations.
If you've owned the property for a number of years, you may have substantial equity.
Keeping the home means keeping that equity invested in the property.
Selling it could make some of that equity available for the next home or other financial goals.
Neither choice is automatically better.
The question is what role you want that equity to play in your overall financial picture.
Turning a primary residence into a rental may also have future tax implications.
Under current federal tax rules, homeowners who meet certain ownership and use requirements may potentially exclude up to $250,000 of gain for a single taxpayer or $500,000 for certain married couples filing jointly when selling a primary residence.
Converting the home to a rental and deciding when to eventually sell it can affect the tax conversation.
There may also be considerations involving depreciation, rental income, expenses, and the eventual sale of an investment property.
These are questions for your CPA or qualified tax professional.
The mortgage professional's role is not to provide tax advice. It's to make sure the financing conversation doesn't happen in isolation from the other financial considerations surrounding the decision.
If you're considering becoming a landlord, think beyond the first year.
How long do you expect to keep the home?
What might maintenance look like over that period?
Do you want the responsibilities that come with owning a rental property?
When might you eventually want to sell?
Keeping the property because you can is different from keeping it because it supports a thoughtful longer-term plan.
Even with the new Fannie Mae guidelines, the departing residence remains part of the overall mortgage analysis.
Cash reserves, available assets, debts, the financing on the new home, and other qualifying requirements may still matter.
There is also the personal side of the equation.
You may technically qualify to own both properties, but how comfortable are you carrying the financial responsibilities of two homes?
That's another reason I like to run the scenarios before a homeowner makes the decision.
Turning a primary home into a rental can touch several areas of your financial life.
Your mortgage professional can evaluate the financing.
Your CPA or tax professional can advise you on tax implications.
Your financial advisor can help evaluate how keeping the property fits into your investment and long-term financial strategy.
A real estate professional can help you understand the local rental and resale markets.
When those conversations happen before the decision is made, you have a much clearer picture of what keeping the property may actually mean.
Fannie Mae's updated guidelines may make it easier for some homeowners to convert their current primary residence into a rental while qualifying to purchase their next home.
That's potentially a valuable new option.
But being able to keep the home doesn't automatically mean you should.
Before deciding, look at the financing, realistic rental cash flow, equity, reserves, future plans, and potential tax considerations.
For San Francisco Bay Area homeowners with substantial value tied up in their current property, comparing those pieces before making a move can be especially important.
The goal isn't simply to determine whether you can own both homes. It's to understand whether owning both supports what you're trying to accomplish.
That's mortgage planning.
