Keep the California House, Rent It, Buy the Next One
Program and regulatory figures verified September 22, 2026. Details change; confirm your scenario with us.
Renting the house you are leaving removes the timing problem. In California it also brings you inside a body of law most accidental landlords have never read.
How the rental income qualifies you
Fannie Mae addresses this in B3-3.8-05, restructured effective September 2, 2026 and binding on all applications dated on or after November 1, 2026. Because the property has no rental history on your tax returns yet, market rent is established from a complete appraisal including market rents, a Single-Family Comparable Rent Schedule on Form 1007, or a market analysis supported by at least three comparable rentals. Lease agreements are not permitted for any departing residence.
That combination is what lets you qualify for the next house without waiting for a sale. More on the Form 1007 page.
The rent cap you are now inside
California's Tenant Protection Act limits annual rent increases to 5% plus local CPI, or 10%, whichever is lower, and permits no more than two increases in any 12-month period. Just-cause termination protection attaches once a tenant has occupied the property for 12 months. The act took effect January 1, 2020 and sunsets January 1, 2030.
This matters to a lender for one blunt reason: if the rent you are counting on cannot be adjusted, the income supporting your file is on a different footing than it would be in a state without the cap.
The exemption, and the way people lose it
Here is the part worth reading twice. A single-family home or condominium that is separately alienable from the title to any other dwelling unit is exempt from those limits, provided the owner is not a real estate investment trust, a corporation, or a limited liability company with a corporate member. An individual renting out a former primary residence usually fits that description.
The exemption is conditional. The owner must give the tenant written notice of the exemption in the exact statutory language, and the requirement is enforced strictly. Without the notice the property is not exempt, even when the ownership structure plainly qualifies. For a tenancy beginning or renewed on or after July 1, 2020, the statement needs to be in the rental agreement.
Most accidental landlords in California qualify for the exemption and never claim it, because nobody told them a notice was involved. We are not the ones to draft it, and we will say so, but knowing it exists before you sign a lease is worth a great deal.
Who this route suits
- Owners whose departing home would cover most of its own payment.
- Owners who would rather hold a California property than liquidate it.
- Owners who are tight on the two-payment test and need documented income rather than borrowed funds.
Compare it with the other two on the structures page, and if you are 55 or older read the Proposition 19 page first, because keeping the original rather than selling it bears on eligibility.
Proposition 19 eligibility and landlord notice requirements are legal and tax questions. Your CPA, a California attorney, and your county assessor own those answers. We flag them because they change the numbers we underwrite.
Frequently asked questions
Can I rent out my California home and still qualify for a new mortgage?
Yes, though it helps less than most sites suggest. Under Fannie Mae B3-3.8-05 the calculation is gross market rent times 75% less that property's PITIA, and a positive result offsets the departing residence's own payment rather than adding to qualifying income. Market rent must be supported by a Form 1007 or an equivalent analysis; lease agreements are not permitted for any departing residence.
Does California rent control apply to my single-family home?
The Tenant Protection Act caps increases at 5% plus local CPI, or 10%, whichever is lower. A separately alienable single-family home or condominium is exempt where the owner is not a REIT, a corporation, or an LLC with a corporate member. The exemption requires written notice to the tenant in the exact statutory language, and without that notice it does not apply.
What happens if I never gave the exemption notice?
The property is treated as not exempt even if the ownership structure qualifies, because the notice requirement is enforced strictly. That is a question for a California attorney rather than a lender, and it is worth raising before you sign a lease rather than afterwards.
Does keeping my old home affect a Proposition 19 transfer?
Proposition 19's base year value transfer moves from a principal residence to a replacement principal residence, and both must be eligible for the homeowners' or disabled veterans' exemption. If you are weighing keeping the original instead of selling it, raise that with your CPA or a California attorney before committing, since it bears directly on eligibility.
