What to know about contractor financing in San Diego

San Diego's construction market runs hot: a dense pipeline of residential remodels, commercial tenant improvements, and infrastructure work means contractors here face the same cash-flow crunch as anywhere — payroll clears every two weeks, but GC payment draws on a 30- to 60-day cycle. The financing products below address that gap, but they're not interchangeable. The wrong product can cost you significantly more than necessary or slow you down when speed matters.

Working capital loans and lines of credit are the most direct solution for short-term gaps. For 2026, SBA 7(a) working capital loans carry rates of 8.5–11% APR, require a 640+ FICO score, 24 months in business, and $150,000–$250,000 in annual revenue for unsecured lines. Approval takes 30–45 days — workable for a line you set up before a project kicks off, but not useful mid-project. Lenders will pull 12 months of bank statements and want to see a debt service coverage ratio of at least 1.25x, meaning your net operating income covers loan payments by a 25% margin. Your total monthly debt service should stay under 45–50% of gross monthly revenue.

Invoice factoring solves the same problem differently: instead of borrowing against future revenue, you sell your outstanding invoices to a factor at a discount. Factors typically advance 80–90% of the invoice face value within 24–72 hours, then remit the balance minus a fee of 1–5% per 30-day period once your client pays. Credit score matters less here because the factor is underwriting your client's creditworthiness, not yours — making this the go-to option for contractors with thin credit histories or those who just landed a large contract with a creditworthy GC. San Diego solar and specialty trade contractors have used this tool extensively; if you're in that segment, the financing structures that apply to solar contractor working capital in San Diego overlap closely with what standard trade contractors can access.

Equipment financing is asset-backed, which is why it closes faster — typically 1–3 days — and is available to borrowers who wouldn't qualify for unsecured lines. Expect a 10–20% down payment and rates tied closely to your FICO tier. Contractors with a 700+ score access the best pricing; fair-credit borrowers (620–679 FICO) typically pay 2–4 percentage points more. One often-overlooked benefit: equipment purchased outright or financed may qualify for a Section 179 deduction of up to $1,220,000 in 2026, which meaningfully reduces the effective cost of the equipment. For San Diego contractors buying or leasing excavators, aerial lifts, or specialty tools, a detailed breakdown of heavy equipment loan and lease options in San Diego is worth reviewing before you sign.

Merchant cash advances (MCAs) are the fastest option — funds in 24 hours, minimal documentation — but the cost is real: the APR equivalent typically runs 80–150%. For a contractor who needs to cover a payroll shortfall this week and has a signed draw payment arriving in 10 days, an MCA can make sense arithmetically. As a recurring financing strategy, it's expensive enough to erode margins on most projects. Use it as a last resort, not a default.

What trips contractors up most often:

• Applying for an SBA loan mid-project when there isn't time for the 30–45 day process
• Choosing an MCA out of urgency and rolling it repeatedly, compounding the cost
• Missing that lenders review 12 months of bank statements — irregular deposits from milestone payments can raise flags even when annual revenue is solid
• Ignoring origination fees (typically 1–3%) when comparing advertised rates
• Not checking for credit report errors before applying — roughly 1 in 5 credit reports contain errors that can suppress your score and your rate
