What to know before you choose a loan type

Contractors in Columbus face a specific problem: the same write-offs that reduce your tax bill also reduce the income a conventional underwriter counts. A sole proprietor running $180,000 through the business but writing off $90,000 in tools, fuel, and subcontractor costs looks like a $90,000 earner on paper. That gap between real cash flow and taxable income is why most self-employed construction professionals need a different documentation path than a salaried buyer.

The main loan types for contractors in 2026:

Loan type	Income doc	Min. FICO	Down payment	Rate vs. conventional
Conventional (Fannie/Freddie)	2 yrs tax returns	620	3–5%	Baseline
FHA	2 yrs tax returns	580 (3.5% down)	3.5–10%	~0.25–0.5% above conv.
Bank statement (non-QM)	12 months statements	620–660	10–20%	1–2 pts above conv.
Alt-doc / stated income (non-QM)	CPA letter or P&L	640+	15–25%	1–2.5 pts above conv.
DSCR (investment properties)	Rental income only	640+	20–25%	1–2 pts above conv.

Who fits which option:

Conventional and FHA work if you've been self-employed for at least two years and your tax returns show enough net income after write-offs to clear debt-to-income limits (generally 43–50% DTI for conventional). FHA's 580 FICO floor is appealing, but Columbus-area loan limits mean FHA is best for purchases under roughly $524,225 in Franklin County. If your after-write-off income qualifies you, conventional usually delivers a better long-term rate.

Bank statement mortgages are the workhorse product for contractors whose tax returns understate real income. Lenders look at 12 months of deposits, then apply an expense ratio — typically 40–50% for construction businesses — to arrive at qualifying income. A contractor depositing $25,000 per month would have qualifying income calculated at $12,500–$15,000 per month, or $150,000–$180,000 annually. You'll pay a rate premium of roughly 1–2 percentage points above conventional, and most programs require 6–12 months of mortgage payments in liquid reserves after closing. A detailed overview of how these programs are structured is at /alt-doc-mortgages.

Alt-doc and stated income products suit contractors whose CPA can prepare a signed profit-and-loss statement or who have strong business checking history but irregular deposit patterns. Rates run slightly higher than bank statement loans, and down payments typically start at 15–20%.

One thing that catches contractors off-guard: the Section 179 deduction. Writing off $1,220,000 in equipment purchases in a single tax year can wipe out all documented income, making conventional approval impossible for that year. If you've taken large equipment deductions recently, a bank statement or alt-doc loan is almost certainly your path for 2026. This overlaps with broader alternative documentation strategies that freelance and 1099 borrowers face across industries, where the same gap between gross earnings and taxable income creates the same underwriting friction.

What trips contractors up most often:

• Mixing personal and business funds in one account (invalidates bank statement underwriting)
• Large one-time deposits from a single project that skew the 12-month average
• Thin reserves — plan for 6–12 months of PITI in liquid accounts at closing
• Opening new business credit lines in the 90 days before application (hard inquiries drop scores 5–10 points each, and new accounts raise underwriting flags)

Self-employed history is another threshold: conventional loans require two full years. Some non-QM programs accept 12 months, but you'll pay for it in rate. If you converted from W-2 to 1099 mid-year, lenders count your clock from the date of transition.

Columbus market context matters too. Franklin County is not a high-cost market, so the conforming loan limit applies at its standard 2026 level — relevant if you're buying in the $600,000+ range, where jumbo non-QM products with bank statement underwriting become the default option. Contractors in neighboring markets like Akron face similar dynamics, since the broader Ohio market sits largely within standard conforming limits.

Start with the guide that matches your documentation situation — tax returns, bank statements, or CPA letter — and you'll have a clear picture of rates, required reserves, and realistic approval timelines within minutes.
