The Quick Read: Start by confirming that your servicer allows recasts, because that decides whether the plan is available at all. A recast is a lump-sum principal payment followed by a recalculated, lower monthly payment on the same rate and the same payoff date. Jumbo loans sit outside the agency recast framework, so the servicer or investor holding your loan decides. Your vested stock is simply the funding source.
This article walks through the whole path. You will see what a recast changes, who decides whether your loan is reviewed, how vested shares turn into cash, and where the plan breaks. You will also see when another tool fits better.
Jumbo payment estimate
The starting figures are an example price in the jumbo range with ten percent down on a thirty-year fixed. Replace them with yours.
Editable benchmark: 7.40% as of October 15, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a jumbo loan quote.
Illustrative starting assumptions: a $1,000,000 price in the jumbo range, ten percent down on the top-leverage lane, a thirty-year fixed structure at the current Freddie Mac conforming benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conforming benchmark, a market reference and not a jumbo loan quote; jumbo rates are set by the lender and the lane at lock and differ from the conforming benchmark. An adjustable-rate scenario is shown at the benchmark for the whole term; the rate after the initial period is unknown. Reserve months and appraisal counts follow the lane sheet for the amount band; the automated finding may require more. Taxes, insurance and dues are editable estimates; closing costs are not included. On most lanes the conforming limit for the county decides whether a loan is jumbo at all; two lanes start at a stated dollar floor instead. Licensed in sixteen states for consumer mortgages.
What Does a Recast Actually Change?
A recast lowers your required monthly payment without changing your rate or your payoff date. You send a lump sum toward principal. The servicer then re-amortizes the smaller balance over the remaining term. Re-amortizing just means recalculating the payment so the loan still ends on schedule.
Fannie Mae’s recast overview describes it this way. The principal drops, the payment drops, and the only change to the note is the new payment amount. Rate and term stay put. On conforming loans, the paperwork is a standard modification and re-amortization agreement, Form 181.
That last point corrects the most common misunderstanding. A recast does not shorten your loan. If you want the loan gone sooner, you keep paying the old amount and let the extra principal shorten the term. A recast does the opposite: it lets the payment fall and leaves the end date alone.
It also is not a refinance. A refinance is a new loan with a new application and new closing costs. A recast is a servicing event on the loan you already have.
| Option | Rate | Payoff date | Monthly payment |
|---|---|---|---|
| Recast | Unchanged | Unchanged | Falls |
| Extra principal, no recast | Unchanged | Moves earlier | Unchanged |
| Refinance | New loan | New term | Depends on terms |
Here is the tradeoff in plain words. A recast gives you budget breathing room. Paying extra without a recast saves a bit more interest over the life of the loan, because you keep the higher payment. Which one wins depends on what you need from your monthly cash flow.
Can Your Jumbo Loan Be Recast?
It depends entirely on who holds and services your loan. A jumbo loan is any loan above the county’s conforming limit, which is set each year by the FHFA. Because jumbo loans sit above that limit, Fannie Mae’s recast rules do not govern them. Fannie Mae’s guidance also ties its framework to loans that met the loan limits when it acquired them.
So the answer comes from the servicer’s policy or the investor’s rules. This is why the internet disagrees. Some pages say jumbo loans are generally eligible. Others say many are excluded. Both are describing real servicers. They just describe different ones.
Here is how it looks from the broker side. Across the wholesale jumbo programs we place files with, loans are structured and held differently. Some stay on a portfolio. Others are sold to private investors. The recast policy follows that choice, and servicing rights can also change hands after closing. Nobody can promise you a recast at the closing table.
If you already hold a jumbo loan, the servicer’s written policy is your answer. If you are buying now and expect RSU vests later, ask about recast policy while you shop. Ask your loan officer how the loan is likely to be held and serviced. Treat the answer as a signal, not a promise. If you want to see how jumbo files are structured, Lendmire’s jumbo loan programs are a reasonable place to start. Those programs run up to 90% leverage and loans up to $5,000,000 on the largest lanes, subject to lender guidelines and full file review.
What to Ask Your Servicer
Call the company you send your payment to, not the lender who originated the loan. Ask these questions and get the answers in writing before you send any money:
- Do you recast this specific loan?
- What is the minimum paydown? Is it a flat dollar amount, a percentage of the balance, or both?
- What is the fee?
- Does the lump sum count, or does cumulative extra principal count?
- How long does processing take?
- Must the loan be current or seasoned?
- What happens to my escrow account?
The percentage question matters more on a jumbo. A minimum set as a share of the balance is a much bigger number on a large loan than a flat floor would be. Minimums and fees vary by servicer, so confirm the current terms directly with yours.
How Do Vested RSUs Become Cash for a Paydown?
Restricted stock units, or RSUs, are a promise of company shares that arrive on a vesting schedule. Vesting means the shares become yours. Until then they have no tangible value to you.
At vest, the shares are treated as income. Your employer usually withholds taxes by keeping some shares or selling them. You receive the net shares. You then sell some or all of them to raise cash. Your net cash is smaller than the headline vest value, and that gap is where plans go wrong.
Withholding may not match your final tax bill. Set aside tax money first, before you commit a dollar to the mortgage. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit. The IRS points to Publication 525 as its reference on how stock compensation is taxed.
Think of it as a waterfall. Gross vest value comes first. Withholding comes off the top. Then you sell net shares and wait for the sale to settle. Then you set aside the tax cushion. What remains is available for the recast.
Two timing notes from the tech side of the table:
- Trading windows and blackout periods can delay when you are allowed to sell.
- Sale proceeds must settle before you can wire them. Plan the recast request around that, not around the vest date.
Step-by-Step: Requesting the Recast
Follow these steps in order. The order protects you if the servicer says no.
1. Confirm eligibility in writing. Use the question list above. Do not sell stock on a verbal maybe.
2. Get the fee, the minimum and the instructions. Servicers often have a form. Some require the loan to be current.
3. Time the stock sale. Sell after vest and after withholding is clear. Keep your tax cushion separate.
4. Send the funds as principal only. Label the payment clearly. Fannie Mae’s servicing guidance shows that on a current loan, the scheduled payment is applied first and the curtailment after. Expect the same logic from most servicers.
5. Wait for the re-amortization. The servicer recalculates from the new balance, the same rate and the remaining term.
6. Verify the new payment in writing. Check the payment, the escrow and the payoff date. The payoff date should not move.
Skipping step one is the classic error. A borrower sells shares, wires the cash and then learns the servicer does not recast that loan. The money is now paid down, the payment has not changed, and the stock is gone.
Does the Recast Need Underwriting or an Appraisal?
Usually not, but servicer policy decides. A voluntary recast is not a new loan. The borrower was fully qualified on the original note amount when the loan was made. It is a servicing event rather than a re-qualification.
On that basis, you would not normally expect a new income review or a new appraisal. Treat that as typical practice for jumbo loans, not a rule. A servicer may still look at your payment history.
This is where tech borrowers get tangled. RSU underwriting rules are about getting a loan, not paying one down. If you used RSU income to qualify originally, those rules did their job at closing. For a new loan, Fannie Mae added RSUs as eligible income when the stock has vested and been distributed without restrictions. Lenders also look at publicly traded employer stock and a history of vesting. Jumbo investors layer their own overlays on top, and those vary.
Unvested or restricted shares do not count as cash for a paydown or for reserves. Only shares you can actually sell help you.
A Worked Example at Jumbo Scale
Picture a tech employee with a jumbo mortgage financed at 80% of the purchase price. A vest cycle lands, taxes are withheld, and the household sells net shares and sets aside a tax cushion. The remainder, a meaningful slice of the loan balance, goes to the servicer as principal.
Now watch what the recast does. The balance falls. The servicer recalculates the payment on the lower balance, using the same rate and the remaining term. The required payment drops by roughly the same proportion the balance dropped. Pay down a tenth of the balance, and the payment falls by roughly a tenth. The payoff date does not move.
This example uses percentages only, because the real result depends on your rate, your term and how far into the loan you are. Your servicer will give you the exact new payment.
Recast vs. the Alternatives
The right tool depends on what you want the cash to do. This table lays out the choices.
| Option | Best when | Main drawback |
|---|---|---|
| Recast | You want a lower payment, same loan | Cash leaves your reserves |
| Extra principal | You want the loan gone sooner | Payment stays high |
| Refinance | Your loan terms need to change | New loan, new closing costs |
| Keep the cash | You value liquidity or have other uses | Payment stays unchanged |
A recast leaves your rate and term exactly where they are. That is a strength if your existing loan is attractive, because a refinance would replace it. It is a weakness if you wanted a different rate or a different term. Those are refinance outcomes, and a refinance is a full new loan with an application and closing costs.
There is also a concentration question that tech employees know well. If much of your net worth sits in employer stock, selling to pay down the mortgage also diversifies you. That can be a real benefit. It can also be a distraction from the real decision, which is liquidity. A tax professional can help you weigh the sale itself.
Where the Plan Breaks: Edge Cases and Risks
Most recast plans fail in one of a handful of ways.
- The servicer declines. Jumbo and portfolio eligibility is servicer-specific. Get approval first.
- You drain your reserves. Reserves are the cash left after closing. They are part of how lenders judge a file, and a recast pulls cash out of them. Keep enough that a job change or a stock drop does not leave you thin.
- The stock moves between vest and sale. If the price falls before you sell, your cash shrinks. Selling at vest, where your plan allows, narrows that gap.
- The tax bill exceeds withholding. Reserve the tax money before you send principal.
- A prepayment penalty applies. Most consumer mortgages cannot carry one. Per the CFPB’s ability-to-repay guide, where a penalty is allowed, it cannot last past three years, and it is capped at 2% of the amount prepaid in years one and two and 1% in year three. Read your note and Loan Estimate anyway. Unusual terms show up most often on non-standard or portfolio jumbos.
- Loan type rules it out. FHA, VA and USDA loans are typically not recastable. Ask, but expect a no.
- Second homes and rentals. Servicers may treat occupancy differently. Ask rather than assume. Occupancy mostly changes leverage at origination, not the recast mechanics.
One naming trap to watch. In federal mortgage rules, “recast” can also mean a rule-driven payment reset at the end of an interest-only period or an adjustable-rate introductory period. That kind of recast usually raises your payment. This article covers the voluntary kind, where you choose to pay down principal and the payment falls.
Does a Lower Payment Help You Qualify Later?
Possibly, but investors differ. A lower required payment can reduce your debt-to-income ratio on a later application. Debt-to-income is your monthly debt payments divided by your monthly income. Across the jumbo lanes we place files with, the ratio ceiling is 50% on the fixed lanes, 45% on the adjustable lanes and 43% on the interest-only lanes, subject to lender guidelines. A smaller payment gives you more room under those ceilings, but each lender reviews the full file.
Do not plan a move around that effect without confirming it. Investors differ in how they treat a post-recast payment, so think of a lower payment as a possible benefit, not a promise.

Frequently Asked Questions
Can I recast a jumbo loan?
Maybe. Jumbo loans fall outside Fannie Mae’s recast rules, so the servicer or investor that holds your loan sets the policy. Some allow it and some do not. Ask your servicer directly and get the answer in writing before you send any funds.
Does a recast change my interest rate or loan term?
No. The rate and the payoff date stay the same. Only the required monthly payment changes, because the lower balance is re-amortized over the remaining term.
Do I need a new appraisal or income check?
Typically not. A voluntary recast is a servicing event, not a new loan, so servicers generally do not re-underwrite. That is common practice rather than a published rule for jumbos, so confirm it in your servicer’s written policy.
Should I recast or just pay extra principal?
It depends on your goal. A recast lowers your required payment. Extra principal without a recast keeps the payment the same and shortens the loan, which usually saves somewhat more interest. If your income is partly variable RSU pay, a lower required payment can make budgeting easier.
Do unvested RSUs count toward a recast or reserves?
No. Only vested shares you can actually sell count as usable funds.
What the Decision Looks Like in Practice
Start with the servicer call, not the stock sale. If the answer is yes, price out the cash after withholding and a tax cushion. Then decide whether a lower payment or a faster payoff serves you better, and keep real reserves intact.
