The short version: a recast lowers your monthly payment without touching your interest rate. A refinance replaces your rate, your term and your loan, and it costs real money to execute. The two fix different problems, and picking the wrong one is a mistake you live with for a long time.
The question comes from owners who just closed on the next house, sold a rental, or landed a bonus. Cash is sitting in the account, the payment feels heavy, and the instinct is to throw money at the mortgage. Whether that helps depends entirely on what your servicer does with the money once it posts.
A recast is a re-amortization, not a new loan
You send your servicer one large principal payment, called a curtailment. The servicer applies it to the balance, then recalculates the monthly principal and interest over whatever term is left, using the rate already written on your note. Everything else stays where it was: same interest rate, same maturity date, same loan number, same escrow account, same lien. Only the balance the payment is computed from changes, so the payment falls.
Fannie Mae spells out the mechanics in its Servicing Guide. Section C-1.2-01, Processing Additional Principal Payments, says that when a borrower asks to have the loan re-amortized after a substantial principal curtailment, the servicer completes an Agreement for Modification, Re-Amortization, or Extension of a Mortgage (Form 181) and reduces the principal and interest payment based on the current unpaid balance, the current interest rate and the remaining loan term. Read that last phrase twice. The current interest rate. A recast cannot improve your rate, and nothing about the process is designed to.
That single fact settles many cases before the math starts. If your note rate has a three in front of it, a recast is almost certainly the only tool that helps, because any refinance on offer today would hand back the rate in exchange for the lower balance. If your note rate starts with a seven, the recast is half an answer and you owe yourself the comparison below.
What your servicer will actually require
Four conditions show up on nearly every recast request form:
- A minimum curtailment. Servicers set a floor, stated either as a dollar figure or a percentage of the unpaid balance. Sending less reduces your balance and shortens the payoff date; it does not reset the payment.
- A flat processing fee. A recast is a clerical event, not an origination, so the fee is a fixed administrative charge rather than a percentage of the loan.
- A current loan. The Servicing Guide language is written around performing loans. A recast is not a hardship tool.
- An eligible loan type. This is where most requests die, and it is worth its own section.
The honest part: none of those thresholds are published by a regulator. There is no federal minimum curtailment and no capped recast fee, and Fannie Mae leaves both to the servicer. The only reliable numbers are on your own servicer request form, so get them in writing before you move money, along with the effective date of the new payment. Our preferred lenders will read a payoff statement with you at no cost.
Conventional yes, FHA and VA essentially no
Recasting lives almost entirely in the conventional world. Loans owned or backed by Fannie Mae and Freddie Mac are routinely re-amortized after a curtailment, and portfolio and jumbo lenders that keep loans on their own books often allow it too, on whatever terms they like.
FHA and VA loans are the opposite. Neither program provides for re-amortizing a performing loan downward after a lump sum. Extra principal on an FHA or VA loan does exactly what extra principal always does when nobody re-amortizes: it shortens the payoff date and cuts lifetime interest, while the required monthly payment stays exactly where it was. A veteran who wants a smaller payment has to refinance, and the cheapest route is usually the Interest Rate Reduction Refinance Loan, which carries a VA funding fee of 0.5 percent of the loan amount according to the VA funding fee rate charts. We work through the rest of that program in our guide to VA loans in the Richmond area.
One more category: if you took over a seller and their existing note, the recast question follows the loan, not the borrower, and government loans keep their restrictions. We covered those transfers in our piece on assumable mortgages in Richmond.
Loan sizes that look like this market
The loans people ask us to recast are sized to the local median, so here is where the median sat last month.

| Richmond Metro | $450,000 | +3.7% | 871 | 22 |
| Chesterfield County | $453,975 | +0.9% | 372 | 22 |
| Henrico County | $425,000 | +7.9% | 229 | 18 |
| Richmond City | $403,500 | -5.3% | 163 | 26 |
| Entire MLS | $430,000 | +5.0% | 1,302 | 28 |

At a $453,975 median in Midlothian and the rest of Chesterfield County, ten percent down lands near a $408,000 loan. Round to $400,000 and the math below reads the same in Short Pump or Manchester.
The arithmetic, run all the way out
Starting point. A $400,000 loan taken in 2024 at 6.875 percent on a 30 year fixed. Principal and interest is $2,627.65. After 24 payments the balance is $391,384 and there are 336 payments left.
Now $75,000 arrives from the sale of a prior home.
Option one: recast. Apply $75,000. New balance $316,384, same 6.875 percent rate, same 336 months remaining. Re-amortize:
$316,384 at 6.875% over 336 months = $2,124.20 per month
$2,627.65 minus $2,124.20 = $503.45 per month lower
Total remaining principal and interest: 336 x $2,124.20 = $713,731
Interest portion: $713,731 minus $316,384 = $397,347
Option two: refinance and apply the same $75,000. Assume you can get 6.0 percent on a new 30 year fixed for the same $316,384. Assume $4,500 in total closing costs. That $4,500 is an assumption for the worked example, not a quote; replace it with the bottom line of your own Loan Estimate.
$316,384 at 6.0% over 360 months = $1,896.72 per month
$2,124.20 minus $1,896.72 = $227.48 per month lower than the recast
Break even on $4,500 of costs: $4,500 divided by $227.48 = 19.8 months
Total remaining principal and interest: 360 x $1,896.72 = $682,819
Interest portion: $682,819 minus $316,384 = $366,435
Option three: refinance without the lump sum. $391,384 at 6.0 percent over 360 months is $2,346.51, or $281.14 below the current payment. Break even on the same $4,500 is 16.0 months. Run this version when the cash is earmarked elsewhere and you only want the rate.
Line the three up and the ranking is not what most people guess. The recast costs almost nothing and instantly removes $503.45 from the monthly obligation, the single biggest swing on the page. The refinance adds another $227.48 and saves about $30,900 in lifetime interest against the recast, but it costs $4,500 up front and pushes the payoff date out by 24 months. It wins on total interest here only because the rate improved by 0.875 points. Cut that to a quarter point and the advantage disappears.
Run your own version. Our mortgage calculator handles the amortization; the inputs you need are the remaining balance, the note rate and the payments left, all on your last statement.
Want the sequence in writing? We keep a Richmond closing timeline checklist that lays out, week by week, what a lender, a title company and a Virginia closing attorney each need from you and when, including the points where a curtailment or a refinance has to be disclosed so it does not blow up a purchase you are running at the same time. Ask us for the Richmond closing timeline checklist and we will send it over.
When a refinance genuinely wins
Four situations, and only four:
- The rate moved enough to clear the costs. Divide total refinance cost by the monthly payment reduction. If that month count is longer than you will hold the loan, stop. The CFPB applies the same test in its guidance on choosing a loan offer: compare total costs, not headline rates.
- You need to change the term. A recast cannot move you from 30 years to 15. Only a new loan can.
- You need to remove someone from the note. Divorce, a departing co-borrower, a parent who cosigned. A recast leaves the obligation exactly as written.
- You need cash out. A recast moves money in one direction only.
Two things a refinance will not do. It will not fix a debt to income problem created by a second property, which is why people in that spot look at bridge loans and HELOCs against the departing residence instead. And it is not the only way to shed mortgage insurance; a large curtailment can put you under the loan to value threshold where cancellation can be requested on the loan you already have, which we walk through in our guide to private mortgage insurance in Richmond.
The Virginia line item people forget
A recast records nothing. A refinance records a new deed of trust, and Virginia taxes that. Under Code of Virginia section 58.1-803, the state recordation tax on a deed of trust runs 25 cents per $100 of the obligation secured. When the purpose is refinancing a debt already secured by an instrument on which the tax was paid, subsection E drops the rate to 18 cents per $100 on the first $10 million of value.
Then section 58.1-3800 lets a city or county add its own recordation tax equal to one third of the state amount. On the $391,384 refinance above, that is $704.49 to the Commonwealth plus $234.83 to the locality, roughly $939 before a single lender or title fee. It is not the largest number on the Closing Disclosure, but it is the one nobody budgets for, and it belongs inside the $4,500 assumption used earlier, not on top of it.
A decision rule for five minutes
- Find your note rate. Below 5 percent, skip the refinance analysis entirely and price the recast.
- Confirm the loan type. FHA or VA, the recast is off the table and the question becomes streamline refinance or nothing.
- Get the servicer minimum and fee in writing.
- Compute the recast payment on your actual remaining term, not on 360 months. Using 360 overstates the savings.
- If a refinance is plausible, get a Loan Estimate and divide total costs by the monthly reduction, then compare that to how long you will really keep the house.
If the honest answer to step five is that you are moving inside three years, neither option is worth much and the cash belongs in the next down payment. Our Richmond area property search shows what that costs. Whichever way you go, get the order of operations right first: ask us for the Richmond closing timeline checklist before you move the money.
Questions we get after the first payment drops
Does a recast lower my escrow payment as well?
No. A recast re-amortizes principal and interest only. In the worked example the entire $503.45 reduction comes out of the principal and interest line, while the tax and insurance portion of the payment is untouched. If your escrow is short, the escrow analysis will still raise your total payment at the next review whether or not you recast.
Will a recast show up on my credit report as a loan modification?
No. No new account is opened and no old account is closed. The account number, the open date and the interest rate all stay the same, and only the reported balance and the scheduled monthly payment change at the next reporting cycle. A recast is a servicing transaction for a performing loan, not a loss mitigation modification, and it is not reported as one.
How soon does the new payment start after I send the money?
Not immediately. The servicer has to post the curtailment, prepare the Agreement for Modification, Re-Amortization, or Extension of a Mortgage, and reset the billing system. Get the effective date of the new payment in writing before you send the funds. Until that date arrives you still owe the old payment in full, and paying the new lower figure early will show as a partial payment.
Can I recast the same loan more than once?
Fannie Mae’s Servicing Guide does not cap the number of re-amortizations, but individual servicers do. Ask two questions in the same email: whether there is a waiting period between recasts, and whether the flat fee is charged again each time. If you expect two lump sums twelve months apart, the answer changes whether you should send the first one now or wait and send both together.
What if my servicer refuses to recast? Is the extra principal wasted?
Not wasted, just slower. On the example loan, applying $75,000 to the $391,384 balance at 6.875 percent without any re-amortization leaves the payment at $2,627.65 and retires the loan in roughly 205 months instead of 336. That is about eleven years earlier. What you do not get is relief on the monthly obligation, which is the thing most people actually need.
Does a recast help me qualify for the next mortgage?
Yes, and this is the most underrated reason to do one. Underwriters count the payment you are actually required to make. A recast lowers the required payment of record from $2,627.65 to $2,124.20, which is a real reduction in your debt to income ratio. Sending the same $75,000 as a plain curtailment without a recast lowers your balance but leaves the required payment, and therefore your ratio, exactly where it was.
Is the recast fee tax deductible, and is the payment reduction taxable?
Neither. A recast is not a taxable event and produces no income to report. The flat servicing fee is an administrative charge, not mortgage interest and not a loan origination point, so it is not deductible as mortgage interest. Your deductible interest simply falls along with the balance. Confirm the specifics with your own tax advisor.
I am buying before I sell. Where does the recast fit in the sequence?
At the end. If you are carrying the new purchase with a bridge loan or a home equity line against the departing residence, the sale proceeds first retire that short term debt. Whatever is left is the curtailment, and the recast request goes in after those funds clear. Recasting before the old house closes spends the cash that was supposed to cover the overlap.
