The Complete Guide to Assumable Mortgages
How to take over a seller's 2-3% mortgage instead of getting a new loan at 6.5%+. Everything from the basics to the closing table.
What is an Assumable Mortgage?
An assumable mortgage is a type of home loan that allows a buyer to take over the seller's existing mortgage balance, interest rate, and remaining loan terms with lender approval. Instead of originating a new mortgage at current market rates, the buyer steps into the seller's existing loan. The loan is legally transferred into the buyer's name through the lender's full underwriting and approval process.
Every FHA loan, every VA loan, and every USDA loan is eligible for assumption — assumability is written directly into these government-backed loan documents. Conventional loans (Fannie Mae, Freddie Mac) are generally not assumable due to due-on-sale clauses.
An assumable mortgage lets the seller of a property transfer the loan balance, terms, and interest rate into the buyer's name. The lender is involved in the entire process. This is a fully legal, lender-approved transaction.
That's the key distinction from "subject-to" deals, where you take over payments without telling the lender and hope nobody notices. Assumable mortgages go through the lender's full approval process. The loan ends up in the buyer's name. Clean, legal, and you keep your peace of mind.
So why does this matter right now? Because millions of homeowners locked in rates between 2% and 4% during 2019-2022. With rates sitting around 6.5% to 7% today, those old loans are worth a fortune. Instead of getting a new loan at today's rates, you can step into the seller's shoes and take over their 2-3% rate.
Mortgage rates have been declining for 40 years before the recent spike. Assumable mortgages were popular in the 1980s when rates hit 16%. Then rates kept falling, assumables became irrelevant, and everyone forgot about them. Like Blockbuster or frosted tips. But they've always been there, written into certain loan documents. They've just been waiting for the comeback tour.
Which Loans Are Assumable?
Not every mortgage is assumable. Conventional loans (Fannie Mae, Freddie Mac) have a "due-on-sale" clause that lets the lender demand full payoff when the property transfers. So those are out.
Government-backed loans are a different story. The assumability is written directly into the loan documents.
All FHA loans are assumable. They make up the majority of assumption transactions. Acceptance rate is around 90% when the offer is competitive and there are no competing offers.
All VA loans are assumable, and non-veterans can assume them. About 10-20% of VA sellers are open to non-vet assumptions. Full VA guide here.
USDA loans are assumable with lender approval. Less common than FHA and VA but the same concept applies. Buyer must meet USDA eligibility requirements.
Conventional loans have a due-on-sale clause. The lender can call the full loan balance due when ownership transfers. There are narrow exceptions (death, divorce, transfer to a trust), but for practical purposes, conventional loans aren't assumable.
How the Process Works
The process takes 45-90 days on average. A little longer than a normal closing, but well worth it for the rate savings. Some servicers can do it in 30 days. Here's the typical flow:

Get Pre-Qualified
Soft credit pull (won't impact your score). We look at income, credit history, and the equity gap coverage plan. Pre-qual is good for about 6 months.
Make an Offer
We submit a purchase agreement just like a traditional sale. The difference is the financing contingency specifies assumption instead of a new loan. I recommend full-price offers on assumables. The seller is giving up a lot (their rate, their entitlement on VA loans). Going in low is short-sighted.
Assumption Application
The buyer applies with the seller's current loan servicer. This is where an assumption processor is critical. These third-party mediators know how to give the bank what they need and keep things moving. I don't do any of these without them.
Underwriting and Approval
The bank reviews the buyer's financials. Credit, income verification, the usual. The bank will ask for paperwork over and over. Things you've already given them. It gets a little annoying, but stay on top of it.
Closing
Once approved, you close just like a traditional purchase. Title transfer, funds disbursed, keys handed over. The loan is now in the buyer's name at the original rate and terms.
The Equity Gap Explained
The equity gap is the difference between a home's current market value and the remaining assumable loan balance. It represents the seller's equity in the property and is the amount the buyer must cover at closing. Buyers typically cover the equity gap with cash savings, gift funds, a HELOC on another property, or a second mortgage. Most buyers put as little as 5% down on the equity gap and finance the rest through a partner lender.
In other words, the equity gap is basically the equity the seller has in the property. And that's what you need to bring to the table.
Example:
$25K on a $525K home. That's less than 5% down. Not bad.
But equity gaps vary. Some properties have $20K gaps. Others have $150K. It depends on how much the seller has paid down and how much the home has appreciated.
How to Cover the Equity Gap
- 1.Cash savings. The simplest route if you've got it.
- 2.Gift from family or friends. FHA allows gift funds for the gap.
- 3.HELOC on another property. Lower rate than a personal loan.
- 4.Loan from a retirement account. You're borrowing from yourself.
- 5.Second mortgage through our partner lender. Put 5% down on the gap, the lender covers the rest up to 80-90% LTV. This is the most common option our buyers use.

The Math
On a $500,000 loan, a 3.25% assumed rate results in a monthly payment of $2,176. The same loan at today's 6.80% rate costs $3,260 per month — a difference of $1,084 every month, $13,008 per year, and approximately $390,000 in total interest savings over 30 years.
Let me show you what this looks like with real numbers. $500K loan, 3.25% assumed rate vs. 6.80% new conventional loan.
| New @ 6.80% | Assumed @ 3.25% | |
|---|---|---|
| Monthly P&I | $3,260 | $2,176 |
| Monthly Savings | -- | $1,084 |
| Annual Savings | -- | $13,008 |
| 5-Year Interest Paid | ~$165,000 | ~$77,000 |
| Lifetime Interest Savings | -- | ~$390,000 |
$390,000 less interest paid over 30 years. That's not a rounding error. That's a life-changing number.
The Blended Rate (Even With a Second Mortgage)
People say "well that second mortgage is going to be like 8% to 10%." Yeah, but let's run the numbers.
Even with that 9% second mortgage, you're saving $900+/month. And there's no prepayment penalty on second mortgages, so you can pay it off early.

FHA Assumptions
FHA loans are the bread and butter of the assumption world. They make up the majority of our closings. Here's what you need to know.
The buyer needs to meet FHA credit and income requirements. That means a credit check, income verification, and debt-to-income analysis. No surprises there. The acceptance rate on FHA assumptions is around 90% when the offer is competitive and there are no competing offers.
One thing to know: if you want to own multiple FHA properties, they need to be at least 100 miles apart. So if you already have an FHA loan in Colorado Springs, you can't assume another FHA within 100 miles. But a VA or USDA assumption would work.
FHA assumptions do come with mortgage insurance (MIP). This carries over from the original loan. Depending on when the seller originated the loan, it may be for the life of the loan or it may drop off after a certain equity threshold. Your assumption processor will clarify this during the application.
The closing costs are typically $5,000-$10,000 plus the assumption processor fee. The processor runs about $750 per side or 1% of the purchase price. Worth every penny for keeping the process on track.

VA Assumptions
VA loans come with a massive perk that most people miss: they're assumable by anyone. You don't need to be a veteran to assume a VA loan.
The catch is the seller needs to agree. Their VA entitlement stays tied to the property if the buyer doesn't substitute their own entitlement. About 10-20% of VA sellers are open to letting a non-veteran assume their loan. We call these "hand raisers" and maintain a private list of them across the Colorado Front Range.
VA assumptions have no PMI. No minimum credit score (it's the reason behind the score that matters, not the number itself). And some of the lowest rates in our inventory, going as low as 2.25%.
The VA actually sent a circular to lenders reminding them they must allow assumptions or risk losing the ability to service VA loans. The government is on the buyer's side here.
If the buyer is a veteran, they can substitute their own entitlement, and the seller gets theirs back immediately. If the buyer is not a veteran, the seller retains partial entitlement based on the county loan limit minus the original loan amount. For El Paso County with an $806,500 limit and a $350K original loan, that leaves $456,500 in remaining entitlement.

Pros and Cons
I want to be transparent about this. Assumable mortgages aren't perfect for everyone. Here's the honest breakdown.
The Upside
- ✓Lock in a 2-4% rate while everyone else pays 6.5%+. Monthly savings of $500-$1,500.
- ✓No PMI on VA assumptions. That alone saves $200-$400/month.
- ✓Lifetime interest savings of $100K-$400K depending on the loan.
- ✓Lower closing costs than originating a brand new loan.
- ✓No appraisal required in many cases (saves $500-$800 and avoids appraisal risk).
- ✓Fully legal. Lender involved the whole way. Not subject-to.
The Downside
- ✗Longer timeline: 45-90 days vs. 30 days for conventional. You need patience.
- ✗The equity gap can be large. If the seller has $100K+ in equity, you need a plan to cover it.
- ✗Banks add friction on purpose. They'd rather you get a new 6.5% loan. Expect paperwork requests and delays.
- ✗Limited inventory. Not every home has an FHA, VA, or USDA loan. You're shopping a subset of the market.
- ✗Many agents don't understand assumptions. That's why working with a specialist matters.
- ✗VA entitlement stays tied if buyer is non-veteran. Some sellers won't agree to this.
The downsides are real. This can be a pain in the ass and requires paperwork. But when you're saving $1,000+/month? Most of our buyers think it's worth the extra effort. We've closed 90+ of these and haven't had a buyer who got into the process fail to close.
Frequently Asked Questions
Can anyone assume a mortgage?
Anyone can assume an FHA loan as long as they meet the credit and income requirements. VA loans can be assumed by anyone too, but the seller has to agree (especially for non-veterans). USDA loans require the buyer to meet USDA eligibility.
What credit score do I need?
FHA assumptions typically require 580+ (same as originating an FHA loan). VA assumptions have no hard minimum. It's the story behind your credit that matters.
How much does it cost?
Plan for $5,000-$10,000 in closing costs plus the assumption processor fee ($750/side or ~1% of purchase price). Still far less than the extra interest you'd pay on a new high-rate loan.
Can I use an assumable mortgage as an investment?
Yes, in certain cases. If you assume a VA loan where the seller leaves their entitlement, there's no occupancy requirement for you. FHA requires owner-occupancy for at least one year. After that, you can rent it out.
What if the deal falls through?
It can happen. The bank can deny the assumption if the buyer doesn't qualify. Your earnest money is typically protected by the financing contingency, same as a traditional purchase.
Do I need a real estate agent who specializes in assumptions?
You don't have to, but I'd strongly recommend it. Most agents have never done one. They don't know the timeline, the paperwork, or how to deal with the servicers. We eat, sleep, and breathe these.
Is subject-to the same as assumable?
No. Subject-to means taking over payments without the lender's involvement or approval. The loan stays in the seller's name. If the lender finds out, they can call the loan due. Assumable mortgages go through full lender approval. The loan transfers to the buyer's name. Keep it legal, keep it clean.
How do I find assumable homes?
We maintain a list of 800+ assumable properties across Colorado, updated daily. Browse listings at assumableguy.com/homes or sign up to get the full list sent to your email.
Can I refinance later?
Yes. You can refinance at any time. But why would you refinance out of a 2.5% rate? The second mortgage (gap loan) can be refinanced or paid off early with no prepayment penalty. Most buyers pay down the second and keep the assumed first.
What happens to my rate if interest rates drop?
Your assumed rate stays the same. It's locked for the life of the loan. If rates somehow drop below your assumed rate (unlikely to go below 2-3% anytime soon), you could refinance then.
