A HELOC is a variable-rate revolving line secured by your home. Fixed second mortgages give a lump sum at a fixed rate. Both preserve your existing first mortgage, which usually matters most when your first is locked below 5%. Here is how the program works specifically for buyers, owners, and investors in San Francisco and the rest of San Francisco County.

San Francisco is a condo-heavy, jumbo-dominant market. HOA financials, project warrantability, and non-warrantable condo lenders make lender selection the single biggest factor in whether a loan closes on time.
A homeowner needing $150,000 for an addition, with a first mortgage locked in at 2.875%.
A cash-out refinance would have repriced the entire balance. The HELOC kept the cheap first mortgage intact and cost a fraction in interest over the project.

Full San Francisco market pageYes. HELOC & Equity Access are available throughout San Francisco County. Access equity without touching your low first-mortgage rate. Mark compares pricing across 80+ wholesale lenders and picks the one whose guidelines fit San Francisco property types and your file.
$1,209,750 (2026 high-balance conforming). Above that amount the file is priced as a jumbo or portfolio loan, which changes reserve and documentation requirements.
Most purchases close in 21 to 30 days, and rush files have closed faster when the appraisal and insurance are ordered on day one. Local considerations here: Condo warrantability reviews, HOA reserve requirements, TIC vs. condo financing.
If your current first is below 5%, almost always HELOC or fixed second. Above 6.5%, a cash-out refi may make sense. We model both against your actual timeline before recommending.
Many lines close in two to three weeks because they use an automated valuation rather than a full appraisal.
