Why they're cheap and fast
The agency already insures your loan; refinancing you into a lower payment reduces their default risk. So they waive the expensive friction: no appraisal (underwater borrowers can still qualify), often no income re-verification, and closing in weeks. Both programs require a net tangible benefit — typically a meaningful rate/payment drop (FHA: combined rate must fall ≥0.5%) — and a clean recent payment history (broadly: no 30-day lates in the last 6–12 months) plus a seasoning period (~210 days from your first payment).
Program specifics worth knowing
- FHA Streamline: you get a partial refund of your original upfront MIP on a sliding scale within 3 years — refinancing in year one or two claws real money back. New UFMIP applies at a reduced streamline rate. MIP duration rules reset per the new loan.
- VA IRRRL: funding fee 0.5% (vs 2.15–3.3% on purchases — see the fee guide), no appraisal, and fee-exempt veterans pay nothing. Fixed-to-fixed must generally drop the rate ≥0.5%; recouping fees within 36 months is a statutory requirement — the lender must show you the math.
- Costs can be financed in both programs (IRRRL) or offset with lender credits — the "no-cash-out-of-pocket" version is standard.
The two catches
- It keeps you in the program. An FHA Streamline keeps FHA MIP — if you've reached 20% equity, a conventional refinance that kills MIP entirely may beat the streamline even at a slightly higher rate (compare via MIP vs PMI and the calculator).
- Term resets still apply. A streamline into a fresh 30 years is still the term-reset trap; ask for a term matching your remaining years.
The 10-minute check
Holding an FHA/VA loan closed when rates were higher? Pull your rate, today's streamline quote, and run the break-even calculator with streamline-level costs (often $1,500–$3,000 effective). Break-evens of 6–18 months are common — which is why lenders market IRRRLs aggressively, and why the offer is often genuinely good despite the salesmanship.
