FHA streamline refinance: the net tangible benefit test

What a streamline refinance is

A streamline refinance replaces an existing FHA-insured mortgage with a new one while skipping parts of the normal process. For a non-credit-qualifying streamline the Handbook says many full-underwriting steps do not apply: ordering or updating an appraisal, the minimum decision credit score and the property eligibility criteria are among them. In return the loan has to prove a benefit to the borrower. That proof is the net tangible benefit, and the Handbook defines it as a reduced Combined Rate, a change from an adjustable-rate to a fixed-rate mortgage, or a reduced term that results in a financial benefit to the borrower.

The Combined Rate, defined

The Handbook measures benefit with the Combined Rate, which is the mortgage interest rate plus the mortgage insurance premium rate. A lender that lowers the interest rate but increases mortgage insurance has not necessarily delivered a benefit by this measure. The reduction in term means the shortening of the remaining amortization period of the existing mortgage. Both ideas appear in the calculator above: enter each Combined Rate as one number, interest rate and annual MIP rate added together, in percent.

Refinances with little or no term reduction

For a streamline with no reduction in term, or a reduction of less than three years, the chart depends on what you hold and what you move into. From a fixed rate into a fixed rate, the new Combined Rate must be at least 0.5 percentage points below the prior one. From a fixed rate into a one-year or hybrid ARM, the new Combined Rate must be at least 2 percentage points below. From an ARM with less than 15 months to its next payment change, going to a fixed rate may not raise the Combined Rate by more than 2 points, while going to a one-year or hybrid ARM requires at least 1 point lower. From an ARM with 15 months or more left, the fixed-rate move again allows up to 2 points higher, a one-year ARM needs at least 2 points lower and a hybrid ARM at least 1 point lower. The chart lets the Combined Rate rise in that case because the Handbook's definition counts a change from an adjustable to a fixed rate as a benefit in itself.

Refinances that shorten the term by three years or more

The second chart applies when the term is shortened by at least three years. The only destination is a fixed-rate mortgage. From a fixed rate, the new Combined Rate has to be below the old one, by any amount. From an ARM, it may be up to 2 percentage points above. Whichever you start from, the combined principal, interest and MIP payment on the new mortgage must not exceed that of the old mortgage by more than $50. This second test is what lets a borrower move from a 30-year remainder to, say, a 15-year loan at a modest cost, with the payment limit keeping the increase small.

A worked example

Suppose an existing 30-year fixed loan has an interest rate of 6.50 percent and an annual MIP rate you add as 0.55, for a Combined Rate of 7.05. A new fixed loan at 6.25 percent with the same MIP rate gives 6.80: 0.25 lower. With no term reduction that fails the 0.5-point test, which needs 6.55 or less. If instead the new interest rate is 5.95, the Combined Rate is 6.50, which is 0.55 lower, and the test is met. Now take the three-year route: the new loan is a 15-year fixed with a Combined Rate of 6.90, lower than 7.05, so the rate test passes, but if the old payment was $1,800 and the new is $1,880, the $80 increase breaks the $50 cap. The rates here are invented to show the arithmetic.

Seasoning and other gates

The net tangible benefit is not the only hurdle. On the date the FHA case number is assigned, the borrower must have made at least six payments on the loan being refinanced, at least six full months must have passed since the first payment due date, and at least 210 days must have passed from its closing date. If the borrower assumed the loan, six payments must have been made since the assumption. Payment history rules also apply: for a non-credit-qualifying streamline the borrower must have made all payments within the month due for the six months before the case number, with no more than one 30-day late payment in that period. All streamlines are underwritten manually; the scorecard findings are invalid. Non-owner-occupied properties and secondary residences are eligible only for refinancing into a fixed-rate mortgage.

Using this page well

A lender computes the charts on actual note rates and premium rates, and premium rates change over time, so the rates above are inputs, not facts. To estimate mortgage insurance for a specific loan, see the FHA MIP calculator, and to judge whether closing costs pay back, use the refinance break-even calculator. A pass here only means this single Handbook test is met.
