There is no single waiting period: a conventional rate-and-term refinance has no agency seasoning rule at all, a conventional cash-out needs the first mortgage being paid off to be at least 12 months old, and an FHA streamline or VA IRRRL needs roughly 210 days and six payments made.
People ask this expecting one number, and there are four, because the clock that applies depends on which loan you have and which refinance you are asking about. Rate-and-term and cash-out are governed differently, FHA and VA run their own calendars, and on top of all of it sits a lender preference that is not a rule at all but stops plenty of applications inside the first six months.
Rate-and-term and cash-out are two different clocks
A rate-and-term refinance replaces the loan with another loan of about the same size. A cash-out refinance replaces it with a larger one and hands over the difference. The agencies police the second far more tightly than the first, because a cash-out is where a loan can be talked into existence on equity that was never tested by a sale.
So on the conventional side there is no seasoning requirement written into the agencies' rules for a rate-and-term. For a cash-out, Fannie Mae's 2023 change requires the existing first mortgage being paid off to be at least 12 months old, measured note date to note date, and at least one borrower has to have been on title for six months before the new loan disburses. There are carve-outs, including inheriting the property and buying out a co-owner under a legal agreement.
The government programs count days, not months
FHA and VA both write their waiting periods in days, and the two count from different events, which is the detail that trips people. Read them as dates on a calendar rather than as a rounded number of months.
- FHA streamline: at least six payments made, at least six full months since the first payment due date, and at least 210 days since the closing date of the loan being refinanced. All three, measured at case number assignment (HUD Handbook 4000.1).
- VA IRRRL: the later of six consecutive monthly payments and 210 days after the first payment due date of the loan being refinanced (38 U.S.C. 3709).
- FHA cash-out: the property has to have been owned and occupied as the principal residence for 12 months, with a clean 12-month payment history where the loan has one, and the new loan is capped at 80 percent of value.
- Conventional rate-and-term: no agency seasoning period, though the appraisal, the equity and the lender's own overlays still apply.
The lender's own six months, which is not a rule
A refinance inside the first few months of a loan often meets resistance that has nothing to do with the agencies. When a loan pays off very early, the money paid to whoever originated it can be clawed back under the agreement that produced it. The industry calls this early payoff recapture, and it means the shop that wrote your loan in March loses money if the same loan is gone in July.
The result is a soft six-month convention, applied unevenly. It is a business term rather than a regulation, it varies from lender to lender, and it is one of the reasons an early refinance is often placed somewhere other than where the original loan was written.
The lump sum that skips the wait entirely
A recast is not a refinance and carries no seasoning period, no appraisal and no new loan. You pay a large amount down against the principal, the servicer re-amortizes the existing note over the remaining term, and the payment falls. The rate does not change, which is what makes it a different tool rather than a cheaper version of the same one.
On a $350,000 loan at 6.5 percent, the calculator's default rate, the payment is about $2,212. Three years in the balance is near $337,500; putting $50,000 against it and recasting over the remaining 324 months brings the payment to roughly $1,884. The fee is usually a few hundred dollars rather than a few thousand, and not every loan permits it, so the note and the servicer decide.
Questions people ask
Can you refinance a mortgage after six months?
On a conventional rate-and-term, often yes, since the agencies set no seasoning period and six months clears most lender conventions. A conventional cash-out normally cannot, because the first mortgage has to be 12 months old.
Is there a penalty for refinancing too early?
Prepayment penalties are rare on owner-occupied loans made since 2014 and are heavily restricted by Regulation Z, so the cost of refinancing early is normally the closing costs of the new loan rather than a charge for leaving the old one. The note says whether one exists.
Does refinancing restart the 30 years?
A new 30-year loan starts a new 30-year amortization schedule, which is why the payment falls even at the same rate. Some lenders will write the new loan for the years remaining instead, which keeps the payoff date where it was.
