The California Buy-Before-You-Sell Guide

Written for California homeowners who have found the next house and have not sold this one. Financing only. Your agent handles the purchase and your assessor handles the assessment.
Step one: the two-payment test
Can your documented income carry the new payment and the existing one at the same time, alongside your other obligations? If yes, you can buy outright and sell on your own schedule, then recast the new loan when the proceeds arrive. No bridge, no rush, no dependency in your offer.
More California households clear this than expect to, particularly those who have owned long enough to have a modest remaining balance. It takes about twenty minutes to find out.
Step two: the Proposition 19 clock
If you are age 55 or older, or severely and permanently disabled, and intend to carry your base year value to the new home, the timing is not cosmetic. The replacement must be purchased or newly constructed within two years of the sale of the original. The 105 percent threshold applies within the first year after that sale and 110 percent in the second, with anything above added to the transferred value permanently.
This is the step that makes California different. Elsewhere, buying before selling is a cash-flow decision. Here it is also a decision about the payment you will make for as long as you own the house. Full detail on the Proposition 19 page.
Step three: check the county limit
The 2026 baseline conforming limit for a one-unit property is $832,750, with a high-cost ceiling of $1,249,125. California is one of the few states with counties at that ceiling, and whether yours is among them changes the financing shape materially. See high-cost counties and loan limits.
Step four: decide between bridge and rental
Falling short on the two-payment test is common and not the end of it. Bridge financing works in California without the constitutional limits that constrain it in some states. Renting the departing home works too, and it removes timing pressure entirely, though the Tenant Protection Act adds rules worth understanding before you commit. Both are compared on the structures page.
Step five: model the real payment
Property tax is inside the payment underwriting measures. In California, where a transferred base year value can sit far below the purchase price, modelling that correctly is the difference between an approval and a decline. Plugging in a generic percentage of purchase price is how California pre-approvals go wrong.

Frequently asked questions
Do I have to sell my California home before buying the next one?
No. If you qualify carrying both payments you can buy first and sell afterwards. If not, bridge financing or rental income from the departing home can close the gap. In California the additional question is how your timing interacts with Proposition 19, since that sets the property tax on the new home.
What is the 2026 conforming loan limit in California?
The baseline is $832,750 for a one-unit property, and designated high-cost counties go to a ceiling of $1,249,125. California has a number of counties at the ceiling, so the applicable figure depends on where you are buying.
Can rental income from my old California home help me qualify?
Often yes. Fannie Mae permits rental income on a principal residence being converted to an investment property, documented with a fully executed current lease and supported by a Form 1007 comparable rent schedule on a one-unit property. It is frequently the strongest lever available when the two-payment test is tight.
How do I know whether to buy first or sell first in California?
It depends on your numbers and, if you are 55 or older, on Proposition 19 timing. The 105% and 110% thresholds and the two-year window all run from the sale of the original property, so the sequence carries a permanent tax consequence in a way it does not in other states. That deserves modelling rather than a rule of thumb.
