Buy Now. Lower Your Payment Later.
A mortgage recast is the move most physician-loan articles never mention. You close with the down payment you have today, then, once the bonus, the partnership distribution or the proceeds from your old house arrive, you pay down the principal and your monthly payment drops. Same rate. Same loan. No refinance.
What a Mortgage Recast Is
A recast (sometimes called a re-amortization) is a lump-sum principal payment followed by a recalculation of your monthly payment over the remaining term. Your interest rate does not change. Your loan term does not change. Your lender simply re-runs the math on a smaller balance, and the payment falls.
That is the whole trick. It sounds small until you compare it to the alternative most people reach for, which is a refinance: a new application, a new appraisal, new income documentation, a new credit pull, closing costs, and whatever the rate happens to be that month. A recast skips all of it.
Why It Matters More for Physicians
Physician income is lumpy in a way underwriting does not reward. You may be buying on a resident salary or a first-year attending contract, with money on the horizon that cannot be counted at closing:
- A signing or retention bonus that pays out after you start
- A partnership buy-in that converts to distributions in year two or three
- Stock or deferred compensation with a vesting date
- The equity in the house you have not sold yet because you had to move first
- A spouse's income that starts after the relocation
A physician loan solves the getting in problem: low down payment, no monthly mortgage insurance up to program limits, student loans treated sensibly. A recast solves the what happens next problem. Together they let you buy the house your career is headed toward, on the timeline your career actually runs on.
How It Works, Step by Step
Close with the down payment you have today
Use the physician program to get in with as little as the program allows. Keep the rest of your cash liquid for the move, the practice, or the reserves underwriting wants to see.
Make your scheduled payments
Many conventional loans become eligible for a recast after a short seasoning period, commonly six monthly payments. Ask before you close so you know your loan's rule.
Make the lump-sum principal payment
When the bonus, distribution or sale proceeds land, you apply them to principal. Minimum amounts apply and vary by lender; it is a meaningful sum, not a rounding error.
The lender re-amortizes
Your payment is recalculated over the remaining term on the new, lower balance. Your rate and your maturity date stay exactly where they were. A modest processing fee is typical.
Recast vs. Refinance vs. Just Paying Extra
| What you want | Recast | Refinance | Extra principal only |
|---|---|---|---|
| Lower monthly payment | Yes | Yes, if rates cooperate | No, payment stays the same |
| Keep your current rate | Yes | No, you take today's rate | Yes |
| New application, appraisal, credit pull | No | Yes, all three | No |
| Closing costs | Small processing fee | Full closing costs | None |
| Pay off sooner | No, same term | Only if you shorten it | Yes |
| Works on any loan | Conventional loans that allow it | Most loans | Any loan |
The honest summary: if your rate is good and your goal is a lower monthly payment, a recast beats a refinance almost every time. If your goal is to be debt-free sooner, extra principal payments without a recast do that. If rates have fallen a lot since you closed, a refinance may be worth its costs. Sean will tell you which one, with the math, not a pitch.
What to Watch Out For
Recast-friendly
- Conventional physician programs that permit recasting
- A known lump sum arriving within the first year or two
- A rate you would rather keep than replace
- Asking the question before you sign, not after
Not every loan recasts
- Government-backed loans (FHA, VA) generally do not recast
- Some jumbo and portfolio products have their own rules or none
- Minimum principal amounts and seasoning periods apply
- A recast does not shorten your term; only extra payments do
Eligibility applies. Whether a specific loan can be recast, when, and for how much depends on the program and the investor behind it. The right time to find out is on your first call, before you pick the program.
A Worked Example, With No Rate in It
A fellow accepts an attending position with a signing bonus payable ninety days after start. She buys before she starts, using a physician program and the down payment she has. Six payments in, the bonus has cleared and the old condo has sold. She sends the combined proceeds to principal and requests a recast. Her rate is untouched, her maturity date is untouched, and her monthly payment drops in proportion to the principal she paid down. She never filled out a second application. That is the entire strategy.
