A non-QM loan qualifies you on something other than two years of tax returns and W-2s, most commonly 12–24 months of bank statements for self-employed borrowers, the property's rental cash flow (DSCR) for investors, or the depletion of a large liquid asset balance over a 60–84 month window. Expect a 660–700+ credit score, 10–25% down, and a rate roughly 1–2.5 percentage points above conventional.
These loans stay on lender or private-investor balance sheets instead of being sold to Fannie Mae or Freddie Mac, which is why the underwriting flexibility and the pricing premium both exist.
