The streamlined-assist is the lightest refinance in USDA's regulation, and one of the lightest anywhere. What it skips is as important as what it requires, so here is both, taken from the federal regulation itself rather than a lender's summary.
Under 7 CFR 3555.101(d)(3), a streamlined-assist refinance has:
Your ratios are not recalculated, so new debts since you bought are not a barrier on their own.
The regulation does not require one. Your payment history on the USDA loan does the work instead.
No loan-to-value test and no property inspection requirement. If the value has dropped, it does not block you.
There is also no appraisal requirement, with one exception: Section 502 direct loan borrowers who have received a subsidy. Lenders may still require inspections or repairs as their own condition, and those costs cannot be financed into the new loan.
It is only for current Section 502 direct or guaranteed borrowers.
Your household's adjusted income must not exceed USDA's moderate income limit, just as at purchase.
No defaults in the 12 months before the refinance application, and the account current for the 180 days before applying.
The loan must be on the same property, which you own and live in as your principal residence.
The new rate must be fixed and must not exceed the rate on the loan being refinanced. No cash out is permitted on any USDA refinance. The new loan cannot exceed the balance being refinanced plus accrued interest, the guarantee fee and reasonable closing costs.
The income limit is the requirement people forget. Household income that has grown past the limit since you bought can rule out the streamlined-assist, even with a perfect payment record. How it compares with USDA's two other refinance options is on compare the three options.

Ten minutes with your current statement is enough to tell you whether the streamlined-assist, a conventional refinance, or standing pat is your best move. The review costs nothing.
