What is an FHA cash-out refinance?
It's a new FHA loan that pays off your existing mortgage and returns part of your equity as cash at closing, per HUD Handbook 4000.1. Your current loan doesn't have to be FHA.
Homeowners use it three ways: funding a real need like a roof or tuition, consolidating expensive debt, or replacing a non-FHA loan when FHA's credit flexibility is the only door open. Unlike the streamline, this is a fully underwritten loan: appraisal, income documentation, credit review, the works. That's appropriate, because the loan is growing against your home rather than just lowering a rate.
FHA cash-out vs streamline: which one?
Simple split: want a lower rate on an existing FHA loan? The streamline is built for that, with limited docs and a $500 cash-back cap. Want actual cash from your equity, or coming from a non-FHA loan? Cash-out is the tool.
