What do self-employed borrowers need to qualify for a mortgage?
There are two honest paths, and the right one depends entirely on what your tax returns show. The first is the full-documentation path: a conventional, FHA, or VA loan that reads your self-employment income from your returns and qualifies you under the same agency rules as a salaried borrower. The second is the non-QM alternative-documentation path, a loan that documents your income a different way, such as from bank deposits, for when legitimate write-offs make your returns understate what your business really earns.
Most self-employed borrowers belong on the full-doc path, and that's where I start, because it's generally the more affordable route. I read your returns the way underwriting does, add back what's legitimately addable, and see whether the income qualifies you the standard way. Only when the full-doc path genuinely understates your income does the non-QM path earn its place, with the honest trade-off that non-QM rates run higher. To be clear about what neither path is: neither one skips documenting your income, and neither one is a no-doc, stated-income, or no-income-verification loan. Ability-to-Repay (12 CFR 1026.43, the CFPB ATR/QM rule) applies to non-QM loans: the borrower's income and ability to repay IS verified through alternative documentation. Non-QM means not a Qualified Mortgage, NOT no underwriting. Never imply ability to repay is not assessed.
What are the full-doc requirements for a self-employed borrower?
On the full-documentation path the requirements are the program's normal rules, applied to self-employment income: generally about two years of self-employment history, net income averaged from your tax returns, and standard credit, debt-to-income, and reserve requirements for whichever program you use. Being self-employed changes the income documentation, not the rest of the qualification.
Those actual rules are covered on the loan guides, so I summarize and link rather than repeat them here. For the conventional rulebook, see my conventional loan requirements; for the government programs, see my FHA loan requirements and my VA loan guide. Each one reads self-employment income its own way and sets its own credit, DTI, and reserve bars. The mechanics of how your income is averaged, and which add-backs like depreciation can lift your qualifying number, get their own page in this hub: see my how self-employed income is calculated guide. The short version is that the full-doc path is the same loan everyone else gets, just with your income documented from your returns.
How long do you need to be self-employed to qualify?
Generally about two years. An underwriter wants enough history to see a track record and average the income, which is why two years is the common benchmark. It isn't an absolute wall, though, and I don't want to state it as one.
Some programs allow a shorter self-employment history in specific situations, for example a borrower with a strong prior work history in the same line of business who recently went out on their own. Whether a shorter history works depends on the program and the investor, so I confirm what your particular file needs rather than tell you a hard universal rule that might not apply to you. The exact treatment for each full-doc program lives with that program: see the conventional, FHA, and VA requirements for the program-specific detail, and on a non-QM loan the history requirement is an investor overlay I verify for your file.
What are the requirements for a non-QM self-employed loan?
Here's the honest answer: there is no single set of non-QM requirements. Down payment, credit, reserves, LTV, and occupancy are all investor overlays that vary by program, and non-QM rates are generally higher than conventional. I verify the current program for your file rather than quote a universal figure or a rate.
A page that hands you "10% down and a 660 minimum" is repeating one investor's overlay as if it were a law, and it isn't. The honest version is that the wholesale investor sets each bar, and those bars differ from one investor to the next. The common direction is real: because the investor keeps the loan's risk instead of selling it to Fannie Mae or Freddie Mac, a non-QM file generally wants a larger down payment and more reserves than a full-doc loan, and credit still matters. How much, exactly, depends on the program, which is why I shop the file across 100+ lenders instead of forcing it through one company's policy. ALTERNATIVE-documentation loan, NOT no-doc/stated-income; the lender documents income from bank deposits and ability-to-repay (ATR) applies. The bank statement loan is the flagship non-QM product, and its mechanics are covered in full on my bank statement loans guide. The table below shows the shape of the non-QM requirements without inventing a number for any overlay.
