In California this is a genuine choice rather than a constrained one, which makes getting the reasoning right more useful.

One practical point: a line of credit is generally easier to arrange while the departing home is still your residence and not yet on the market. Owners who wait until the house is listed sometimes find the options narrower than they expected.

What is specific to California

Availability. California does not impose a constitutional ceiling on what can be secured against a primary residence, so this comparison runs on its merits here. In Texas, by contrast, all homestead debt is capped at 80 percent of value and a subordinate line cannot sit behind a home equity loan at all, which removes half the comparison before preference enters into it.

The other California-specific factor is Proposition 19 timing, since the thresholds run from the sale of the original property and both of these structures exist to let you buy before that sale happens. See the Proposition 19 page.

The route that often beats both

Not borrowing against the old house at all. If income supports both payments, buy and recast when the proceeds arrive. If it nearly does, rental income from the departing home under Fannie Mae B3-3.1-08 frequently closes the gap, documented with a fully executed current lease and a Form 1007 comparable rent schedule.

All three are compared on the structures page.

Your real estate agent handles the purchase itself and your county assessor decides your assessment. We handle the financing: what you qualify for, how the equity gets used, and what the payment looks like once the dust settles.

Frequently asked questions

Can I use a HELOC to buy before selling in California?

Yes. California permits home equity lines against a primary residence, and a line arranged before the home is listed is often the simplest source of a down payment. What it does not do is improve your debt ratio, since the drawn balance becomes an obligation alongside your existing mortgage.

Which is better for a California move-up, a bridge or a line of credit?

A bridge is built around one transaction with a defined exit, which suits a move-up purchase. A line suits ongoing flexibility and is usually easier to arrange before listing. Both add an obligation, so where the constraint is your ratio rather than your liquidity, neither is the answer.

Why is this comparison different in Texas?

Because Texas caps all debt secured by the homestead at 80 percent of fair market value and prohibits a subordinate home equity line behind a Section 50(a)(6) loan. California imposes no equivalent constitutional ceiling, so both instruments are genuinely available here.
