What Is a Mortgage Recast? California 2026 Guide
QUICK ANSWER
A mortgage recast re-amortizes your loan after you make a large lump-sum principal payment, lowering your monthly payment while keeping your existing rate and term. It’s ideal in 2026 for homeowners with a low pandemic-era rate who come into cash and want a smaller payment without refinancing.
If you have a low mortgage rate and a chunk of cash, refinancing at today’s higher rates makes no sense — but there’s a lesser-known tool that lowers your payment while keeping that rate: the mortgage recast. Here’s how it works in California in 2026, and when it beats both refinancing and simply prepaying.
How a recast works
You make a large lump-sum payment toward principal — say $50,000 — and the lender re-amortizes the loan over its remaining term at your existing rate. The balance is now smaller, so the monthly payment drops, but the rate and payoff date stay the same. Most lenders charge a small fee (often a few hundred dollars) and require a minimum lump sum.
The key difference from a refinance: you keep your current loan and rate. Nothing is re-underwritten — no appraisal, no credit pull, no closing costs beyond the recast fee.
Recast vs. refinance vs. prepay
Refinance replaces your loan — great when rates drop, terrible when yours is already below market. Prepaying (just sending extra principal) shortens your loan but doesn’t lower the required monthly payment. A recast is the middle path: it lowers the required payment while keeping your rate. If you have a sub-4% mortgage and a windfall, recasting almost always beats refinancing in 2026. See our refinance timing guide.
When a recast makes sense
Recasting shines when you: hold a low rate you don’t want to lose, receive a lump sum (bonus, inheritance, home-sale proceeds, RSU vesting), and want lower monthly cash flow rather than a faster payoff. It’s popular with move-up buyers who buy first, then recast after their old home sells — pair it with our bridge loan guide.
The limits
Not every loan is eligible: most conventional loans allow recasting, but FHA, VA, and USDA loans generally do not, and jumbo rules vary by lender. There’s usually a minimum lump sum and a modest fee. Since you keep your existing servicer, start by asking them for their recast policy — or let us check whether your loan qualifies and whether a recast or another move fits your goal.
Frequently asked questions
What is a mortgage recast?
It’s when your lender re-amortizes your loan after a large lump-sum principal payment, lowering your monthly payment while keeping your existing rate and term. Unlike a refinance, nothing is re-underwritten.
Is recasting better than refinancing?
If your current rate is below today’s market — like a pandemic-era sub-4% loan — recasting is almost always better, because it lowers your payment without giving up your low rate or paying closing costs.
Which loans can be recast?
Most conventional loans allow recasting. FHA, VA, and USDA loans generally do not, and jumbo policies vary by lender. Check with your servicer or ask us to confirm your loan’s eligibility.
How much does a mortgage recast cost?
Typically a small flat fee (often a few hundred dollars) plus a required minimum lump-sum principal payment. There’s no appraisal, credit pull, or full closing-cost package like a refinance.
