Home Financing in San Francisco, CA: A Real Guide for Real People

Buying a home in San Francisco feels like a sprint, but the financing side is a marathon. Prices are high — median home prices routinely clear a million dollars — and that means lenders scrutinize applications hard. What most people do not realize is that the first lender who says no is rarely the last word. There are layers to this market: conventional banks sit at the top, but below them are credit unions, CDFIs (Community Development Financial Institutions), city-run down-payment programs, and state programs through CalHFA. Each layer has different rules about credit scores, income documentation, and immigration status. Your job is to figure out which layer fits your situation, not to force yourself into the one your coworker used. Start by knowing what you have — income documentation, credit history or lack of it, savings, and whether you have a Social Security number or an ITIN.

Before you talk to any lender, get these five things lined up. First, know your income documentation. If you are self-employed, gather two years of tax returns and a year-to-date profit-and-loss statement. If you use an ITIN, ITIN-friendly lenders will ask for this specifically. Second, pull your credit report from all three bureaus for free at annualcreditreport.com. Dispute any errors now — do not wait. Third, calculate your debt-to-income ratio. Most programs want your total monthly debt (including future mortgage) to stay below 43 to 45 percent of your gross monthly income. Fourth, know your down payment number. San Francisco has city-funded assistance for first-time buyers, but you still need skin in the game — even 3 to 5 percent matters. Fifth, talk to a HUD-approved housing counselor before any lender. In San Francisco, counseling is available in Spanish and other languages through local nonprofits and is often free. Counselors do not sell you anything — they help you see the full picture.
