Yes — self-employed borrowers can qualify for a conventional loan in Tampa, but the income math is different. Lenders look at your net business income after expenses on your tax returns, not gross revenue, and Fannie Mae's standard approach generally wants a two-year track record of that income before counting it toward qualification.
That one shift — from gross to net — is where most self-employed Tampa buyers either sail through underwriting or get stuck. The rest of this guide walks through what counts as self-employed, exactly which documents a conventional lender will ask for, how your write-offs affect your approval, and what Florida-specific closing costs to budget for.
Who counts as self-employed for a conventional loan in 2026?
For mortgage purposes, you're generally considered self-employed if you own 25% or more of a business. That threshold applies whether you're a sole proprietor, a partner, an S-corp owner, or an LLC member — if your ownership share hits 25%, the lender underwrites your income using self-employment rules rather than W-2 rules.
This matters because it changes which tax forms the lender reads, how income is averaged, and what supporting documents you'll need to produce. At Bay to Bay Lending, our conventional and jumbo loans team works through this question early, because the answer shapes which tax returns you'll need to pull and how far back the file has to go.
How many years of self-employment income do lenders require?
Fannie Mae's standard approach generally calls for a two-year history of self-employment income, and most conventional lenders substantiate income across those two years to verify consistency. In some circumstances, a one-year exception may apply if the most recent tax return documents a full 12 months of self-employment income and the borrower has relevant prior experience in the same line of work.
That exception is not automatic — the lender has to be comfortable the income is stable and likely to continue. If you left a W-2 job in your field and launched a business doing similar work, you're a better candidate for the one-year path than someone who pivoted into a brand-new industry.
What documents will a Tampa conventional lender ask for?
Expect to produce two years of personal federal tax returns with all schedules, two years of business tax returns, any K-1s, a current year-to-date profit-and-loss statement, and both business and personal bank statements. Lenders also want proof the business exists and has been operating — typically a business license or documentation of ownership share and time in operation.
For a sole proprietor, the lender's starting point for income calculation is generally your Schedule C net profit — not gross receipts on line 1. Partnerships and S-corp owners get a parallel treatment using K-1 income and business returns. If you also have W-2 income from a side job, bring paystubs and W-2s for that piece too; lenders may request earnings statements, W-2 forms, and tax returns to verify the full picture.
A quick view of the paperwork by business structure
| Business structure | Primary tax form | Starting income figure | Also typically required |
|---|---|---|---|
| Sole proprietor | Schedule C | Schedule C net profit | YTD P&L, bank statements, business license |
| Partnership / LLC | Form 1065 + K-1 | K-1 ordinary income | Business returns, YTD P&L, ownership documentation |
| S-corporation | Form 1120-S + K-1 | K-1 income + W-2 wages | Business returns, YTD P&L, ownership documentation |
Why do my tax write-offs lower what I can borrow?
Every deduction that lowers your tax bill also lowers the income a lender can count toward mortgage qualification. The same depreciation, home-office deduction, vehicle expense, or Section 179 write-off that shrinks your April tax check also shrinks the net income on Schedule C or your K-1 — and that net number is what the underwriter uses.
Some add-backs are allowed (depreciation and depletion are the common ones), but most legitimate business expenses stay subtracted. If you're planning to buy within the next couple of tax years, it's worth modeling your returns both ways — maximum deductions versus qualifying income — before you file. This is one of the single most important planning conversations a self-employed buyer can have.
What alternatives exist if my tax returns don't tell the full story?
Some lenders offer alternative documentation programs — often based on 12 or 24 months of bank statements — for self-employed borrowers whose tax returns don't fully reflect what the business actually earns. These programs can carry different terms than a standard conventional loan, so they're a tool for a specific situation, not a default.
A traditional conventional loan, typically repaid over a 30-year period, remains the lower-cost path when your documented net income supports the purchase price you want. Bay to Bay Lending offers home purchase loans for first-time buyers, move-up buyers, and others, and we help borrowers weigh conventional against alternative-doc options based on what the numbers actually say.
What Florida closing costs should Tampa self-employed buyers budget for?
Florida charges a documentary stamp tax on recorded mortgages at 35 cents per $100, or portion thereof, of the amount secured — a line item that doesn't exist in every state and often surprises relocating buyers. According to the Florida Department of Revenue, on a $300,000 mortgage that works out to approximately $1,050 in doc stamps alone.
Florida also imposes a nonrecurring intangible tax on obligations secured by Florida real property, so confirm the full closing-cost picture with your lender and closing agent before you commit. In South Tampa, Hyde Park, Seminole Heights, and the neighborhoods around the Westshore business district, these state-level fees apply equally — they're a function of the mortgage amount, not the ZIP code.
How do self-employed Tampa borrowers avoid last-minute surprises?
The biggest avoidable costs happen between application and closing, not before. From Bay to Bay Lending's conventional & jumbo loans team: Letting a rate lock expire is a big one. Delays from slow documents or a pushed-back closing can mean extension fees or a worse rate. People also don’t realize conventional pricing depends on credit score and down payment. A credit score drop or a change to how much they put down can change the rate after they’ve been quoted. New credit, big unexplained deposits, and a low appraisal can all add cost at the closing table. Lock at the right time, stay on top of document requests, and don’t change anything financial without calling us.
For a self-employed borrower that advice lands even harder, because business deposits, draw transfers between accounts, and quarterly estimated-tax payments can all look like "large unexplained deposits" to an underwriter who doesn't know your workflow. Flag unusual activity early and your file moves faster.
The mortgage process is no walk in the park—it’s more like going to war. But if I had to go to war, I’d take DJ with me. As an entrepreneur, I’ve done all kinds of transactions, and I have to say, even when everything came against us, DJ and his team fought hard for the win and got the job done. Hands down one of the most dedicated and hardworking teams I’ve ever worked with. Highly recommend!
Frequently asked questions
Can I use one year of tax returns instead of two?
Possibly. Fannie Mae allows a lender to consider less than two years of self-employment income if the most recent tax return documents a full 12 months of self-employment and the borrower has relevant prior experience in the same field. Approval isn't automatic — the underwriter has to be comfortable the income is stable and likely to continue.
Does the lender use my gross revenue or my net profit?
Net profit. For a sole proprietor, the lender's starting point is generally Schedule C net profit, not gross receipts. Partnership and S-corp owners are evaluated using K-1 income plus any wages from the business. Gross revenue is almost never the qualifying figure on a conventional loan, which is why aggressive write-offs can shrink your approval amount.
What ownership percentage makes me "self-employed" to a lender?
Twenty-five percent or more. If you own 25% or more of a business, mortgage lenders generally underwrite you as self-employed regardless of how you file personally. That triggers the full self-employed documentation package — personal and business returns, K-1s, a year-to-date profit-and-loss statement, and business plus personal bank statements.
How much is Florida's documentary stamp tax on my mortgage?
Florida's documentary stamp tax on a recorded mortgage is 35 cents per $100, or portion thereof, of the amount secured. On a $300,000 mortgage that works out to about $1,050. Florida also imposes a separate nonrecurring intangible tax on obligations secured by Florida real property — confirm the full figure with your closing agent.
Will heavy business deductions hurt my mortgage approval?
Often, yes. Write-offs that lower your tax bill also lower the income a lender can count toward qualification. Depreciation and depletion can typically be added back, but most other deductions stay subtracted. If you're planning to buy within a year or two, discuss the tradeoff with your tax preparer and your lender before you file.
What if my tax returns don't reflect what my business really earns?
Some lenders offer alternative documentation programs — commonly bank-statement loans — for self-employed borrowers whose returns understate actual cash flow. These programs can carry different terms than a conventional loan. A traditional conventional loan is usually cheaper when your documented net income supports the purchase price, so compare both paths before committing.
