Mortgage Financing for Self-Employed Contractors in San Diego, CA

Scan the guides linked below, pick the one that matches how your income is documented — bank statements, 1099s, or a full P&L — and go straight there. If you're still orienting yourself on which loan type fits a contractor's situation in San Diego, the overview below will get you up to speed fast.

What to Know Before You Apply for a Contractor Home Loan in 2026

San Diego's median home price sits well above the national average, which means loan amounts, down payment dollars, and rate decisions carry more weight here than in most markets. Contractors shopping for a mortgage in 2026 are generally choosing between three paths: conventional/FHA loans (if your tax returns can support the income), alt-doc mortgages that qualify you on bank deposits or assets instead of Schedule C net income, and non-QM products like DSCR or stated-income loans.

Quick comparison — the three main paths for contractor borrowers:

Loan type	Income doc used	Min. FICO	Rate vs. conventional	Best for
Conventional	Tax returns (2-yr avg)	620	Baseline	Contractors with modest write-offs
FHA	Tax returns (2-yr avg)	580 (3.5% down)	+0.1–0.3%	Lower FICO, first-time buyers
Bank statement (non-QM)	12 months deposits	620–640	+1–2 pts	Heavy write-off, high gross revenue
1099 / P&L only	1099s or CPA letter	640+	+1–2 pts	Subcontractors, sole proprietors

Why tax returns trip up most contractors

A GC pulling $280,000 in gross receipts but deducting $160,000 in legitimate business expenses shows $120,000 on the Schedule C — and lenders underwriting a conventional loan use that net figure. At a 43–50% debt-to-income ceiling (the standard for conventional and FHA), $120,000 in qualifying income may not support a San Diego purchase price in the $800,000–$1,000,000 range without a large down payment. That's the core problem non-QM bank statement loans solve: lenders look at 12 months of business deposits and apply an expense ratio — typically 40–50% for construction businesses — to arrive at a usable income number that better reflects your actual cash flow.

Contractors in similar high-cost markets — including those applying in Alexandria, VA, where conforming limits and income documentation standards mirror what San Diego buyers face — report the same pattern: strong gross revenue, thin tax-return income, and a non-QM or bank statement loan as the practical solution.

The numbers that separate the options

Conventional loans require a minimum 620 FICO and two years of self-employment history verified by tax returns. FHA drops the floor to 580 FICO for 3.5% down. Both use the same two-year average income from your Schedule C or S-corp return. Non-QM bank statement programs carry a rate premium of 1–2 percentage points above conventional rates — meaningful on a $900,000 loan, but often the only realistic path for contractors whose write-offs do their job too well on paper.

Cash reserves are a second frequent stumbling block. Non-QM lenders require 6–12 months of mortgage payments in liquid reserves at closing. On a $6,500/month payment, that's $39,000–$78,000 sitting in an account they can verify. Contractors who keep capital in equipment, vehicles, or job-deposit accounts need to plan well ahead of their application date.

Credit score directly affects your rate tier. Borrowers in the 640–679 fair-credit range pay roughly 1–3 percentage points above prime-borrower pricing. Getting from 660 to 720 before you apply can be worth more than shopping four lenders on the same day. Note that each hard inquiry typically costs 5–10 FICO points, so avoid opening new trade lines or pulling credit at multiple lenders without a rate-shopping strategy.

One factor many contractor borrowers overlook is tax planning strategy. The same aggressive deduction approach that reduces your tax bill also reduces your qualifying income. Thoughtful quarterly payment planning and working with a CPA who understands mortgage qualification before you file can let you calibrate write-offs to keep qualifying income viable — especially if you're 12–18 months from buying.

What San Diego-specific factors matter

San Diego County's conforming loan limit for 2026 is elevated relative to most of the country, which extends the conventional/conforming option to more buyers at higher price points. Even so, many San Diego contractor purchases fall into jumbo or non-QM territory simply because of local prices. Non-QM jumbo programs for self-employed borrowers do exist but carry stricter reserve and FICO requirements than standard non-QM. Budget for a 20–25% down payment if you're targeting a non-QM jumbo. Mortgage options designed for freelancers with irregular 1099 income follow the same non-QM logic and the same lender pool that serves San Diego construction professionals.
