For agents
How do I set expectations with a buyer and seller?
Four things to say up front:
- Timeline. Thirty to forty-five days is common, and it varies by servicer.
- The buyer still qualifies. Income, assets, employment, credit and debt-to-income, the same as any loan.
- The seller comes off the loan when the release is issued. The servicer approves the buyer, then releases the seller. Expect it, but treat it as a step in the deal rather than a formality, and get the release in writing.
- Mind the equity gap. Where the home is worth more than the loan balance, the buyer covers the difference in cash or with a second loan.
How do I confirm that my listing is assumable?
A pre-listing check checks assumability, rate, terms and loan type against our database of assumable listings nationwide.
To put the rate in your marketing, verify it: we cross-reference the seller’s mortgage statement against a variety of data sources to confirm accuracy, then issue a Verification of Loan (VOL) report. Start that from the pre-listing check or your listings dashboard.
Why should I offer mortgage assumption as an option when selling a home?
An assumable loan opens the listing to buyers who can’t reach the payment on a new loan. If you want a line of buyers down the block at your open house, promote the rate.
It also appeals to buyers staying conservative on monthly payment, who would rather not stretch past a target price.
Can I sell a home at a higher price if the mortgage is assumable?
You aren’t only selling the home, you’re selling the home with its mortgage. The right to convey the loan is written into the mortgage contract, and while rates are where they are, it’s a marketing point worth making.
It gives you leverage in negotiation and drives foot traffic, which is what creates demand.
What's needed from my seller?
One recent mortgage statement, as an image or PDF. You can upload it yourself, or send your seller a secure link to upload it.
How does RetroRate verify a loan?
We cross-reference the seller’s mortgage statement against a variety of data sources including public records and county recorder information to confirm accuracy, then issue a Verification of Loan (VOL) report.
Is this safe and secure?
Our system uses the statement for verification only. It’s deleted automatically as soon as verification is complete.
What loans qualify?
VA and FHA loans are assumable and supported on RetroRate.
How long does verification take?
Our automated systems can usually verify within seconds. Sometimes we need additional info from you, or need to review a statement by hand if it’s missing information or is unclear, though the turnaround is still quick.
Is there a subscription?
No. Verification is priced per listing, with no subscription and no renewal, and the badge stays up for the life of the listing.

For brokers and team leads
How do my agents get access?
You set the office up and your agents sign in. There’s nothing to install and no integration to wait for, so an office can be working the same day.
Where you’d rather they arrive through your own tools, we set up single sign-on and they reach RetroRate from where they already work.
What does it cost?
One monthly subscription for the whole office, with verifications included. An agent who isn’t on a broker plan pays per listing instead.
We’ll walk you through plans, options and pricing on a demo.
Do verifications cost extra?
Not on a broker plan. Verifying a listing is part of the office subscription, however many your agents run. Agents without a plan pay per listing.
Will RetroRate contact my clients?
No. RetroRate is built for real estate professionals, and your listings and your clients stay yours.
A consumer only reaches us by their own hand, by installing the VHS extension to see assumable loans while they browse, and the agent they invite from it is their own.
Where does the data come from?
MLS data, county records and servicing records, assembled into one view of which homes carry a loan a buyer can take over, and scored by RetroMatch™ for how much that loan could save.
Verification goes a step further: we cross-reference the seller’s mortgage statement against a variety of data sources to confirm accuracy, then issue a Verification of Loan (VOL) report.
How current is the data?
It updates through the day rather than once a night, so a listing that changes hands, drops its price or comes off the market doesn’t sit stale on your dashboard.
Can I see which agents are marketing their assumable listings?
Yes. The dashboard runs from the whole company down to an office, a team or a single agent, and each listing shows where it stands, from first detected to fully verified.
That’s usually how brokers find the quiet ones: a listing sitting on a rate nobody has put in the remarks.
Can we check an address before it lists?
Yes. Run a pre-listing check on any address in the country, and take the answer into the listing appointment. A listing that starts verified is marketed from its first day on the market rather than its thirtieth.
Do my agents need to become assumable loan experts?
No. RetroRate finds the listings, verifies the loan and gives your agents the comparison to show a buyer: the assumable payment next to a new loan at today’s rates, at the same cash to close.
Qualification and approval stay where they belong, with the lender or servicer holding the mortgage. RetroRate takes no part in loan or credit decisions.
Can we use the data in our own tools?
Yes. Everything on the platform runs on an API: check one address, sync your whole book of listings, or subscribe to changes as they happen. If your brokerage has a developer, the docs are here.
For MLSs
How does our MLS integrate with RetroRate?
The easiest integration is simply providing access to RetroRate through your SSO provider, like SolidEarth. We can also integrate directly into your MLS software with Cotality Matrix and FBS Flex compatibility.
What does this cost our MLS?
Access to RetroRate is free to the MLS. Your members get assumable search and the data behind it at no cost to you.
There are add-ons beyond that, which some MLSs choose to subsidize for their agents and broker teams and some leave to the brokerage. We’ll go through the options on a demo.
What do you do with our data?
We use your feed to surface assumable listings for your members. We don’t resell it, and we don’t use it to build a product that competes with the MLS.
Verification works from a document the seller provides, not from your feed: we cross-reference the seller’s mortgage statement against a variety of data sources to confirm accuracy, then issue a Verification of Loan (VOL) report.
Who supports our members with assumable questions and using your site?
We do, on both counts. How an assumable loan works, and how to use RetroRate, come to us rather than your help desk, so putting this in front of members doesn’t add to your support load.
How long until our members have it?
Days. Give your members single sign-on and they reach RetroRate from where they already sign in, with no deep integration and no waiting on your vendor’s release calendar.
Where you’d rather the data sat inside the search they already open, we integrate directly with Cotality Matrix and FBS Flex. That path takes longer, and it isn’t the only way in.
Can a member or a listing opt out?
Assumability is a fact about the loan on a property, not about the agent or the brokerage, so it isn’t a profile setting.
What members see, and how it’s displayed, follows your rules. Tell us how you want it handled and we’ll set it up that way. Should a listing agent object to display of their assumable information, we can of course remove their listing from our site.
For buyers and sellers
What's an assumable loan?
An FHA or VA loan that a buyer can take over at the seller’s original rate, instead of getting a new loan at today’s rate. The buyer is qualified by the original servicer, and once the servicer approves them and issues the release, the seller comes off the loan.
What is a mortgage assumption?
A buyer takes over the seller’s existing mortgage, with its terms, interest rate and balance, instead of getting a new one. The buyer’s name replaces the seller’s, the loan is re-recorded at the county, and once the servicer approves the buyer and issues the release, the seller comes off the loan.
What types of mortgages can be assumed?
FHA and VA loans are generally assumable. Conventional loans usually aren’t, unless the mortgage agreement says so.
Why would a buyer choose a mortgage assumption?
To take over an interest rate nobody can get today. Over half of homeowners in the United States have a mortgage under 5%, and a fifth have one under 3%, so assuming the loan can save hundreds of dollars a month and far more over the life of it. (Rate shares: Mortgage News Daily and Compass, 13 July 2026.)
How does a mortgage assumption differ from getting a new mortgage?
In an assumption the buyer takes over the terms and balance of a loan that already exists. A new mortgage is a new loan, at today’s rates and terms.
Who qualifies for a mortgage assumption?
You have to meet the current VA or FHA requirements. That usually means a credit score of at least 580, though around 620 is preferred, and a debt-to-income ratio under 50%. As with any loan, your package shows income, savings and employment.
A VA loan. You don’t have to be a veteran to assume one, though not every veteran will allow a non-veteran to, because it ties up their entitlement. Investors can sometimes assume a VA loan without living in the home.
An FHA loan. You attest that the home will be your primary residence for the next year, and you’ll likely need to move in within 60 days of completing the assumption.
Does RetroRate approve me for the loan assumption?
No. The lender or servicer holding the mortgage handles qualification and approval, usually working with the VA or FHA. RetroRate takes no part in loan or credit decisions.
What are the costs associated with a mortgage assumption?
An assumption fee set by the lender, closing costs, and a payment to the seller where the home is worth more than the mortgage balance. That last one is usually called the equity gap.
How long does the mortgage assumption process take?
Around 45 days is typical, depending on the lender and how quickly the buyer meets its requirements.
Telling the servicer at the outset that an assumption is coming shortens it considerably, because the paperwork starts moving before it’s needed.
Can the seller or buyer negotiate terms during a mortgage assumption?
Not the mortgage terms: those transfer as they are. Everything else is on the table, including the purchase price and who pays which closing costs, exactly as in a sale with a new loan.
What is my responsibility as the seller?
Give accurate information about the loan, work with your lender, and make sure the buyer meets its requirements. Once the process is moving, the work sits largely with the buyer and their agent, as in any other transaction.
What happens to seller liability after the buyer assumes a mortgage?
The seller comes off the loan once the servicer approves the buyer and issues the release. That’s the normal outcome of an assumption, and it’s what the process is built to do, but it’s a step that has to actually happen rather than something the closing takes care of by itself. Until the release is issued, the loan is still the seller’s. Ask for it in writing and keep it.
Will the assumption process delay the sale of my home?
It can take longer than a conventional sale. Checking assumable status before listing and gathering the servicer’s requirements early cuts most of that back.
Do I need to notify my lender about the assumption?
Yes. Contact the servicer as soon as you accept an offer of assumption, so they have permission to work with the buyer and the buyer’s agent. They’ll put a letter of authorization in place and collect the buyer’s documents, much as they would when originating a loan.
How does the remaining loan balance affect the sale price?
The balance sets how much the buyer covers in cash or other financing to reach the home’s value. Either way the seller takes out their equity, often at a higher price than a conventional sale.
How do I know if a mortgage is assumable?
Assumable loans are close to invisible in standard listing data. RetroRate finds them, and real estate professionals reach that data through their MLS or their brokerage: if you’re with LERA MLS, Beaches MLS or MIAMI REALTORS, you may already have access from your MLS dashboard.
As a buyer, ask your agent, or install RetroRate VHS to see assumable loans while you browse.
What documents do I need to provide for a mortgage assumption?
It depends on the loan you’re assuming, but buyers usually provide proof of income, tax returns, credit history and other financial documents for the lender. Get a standard pre-approval letter too: it’s what makes sellers and their agents take the offer seriously.
Do I need a down payment for a mortgage assumption?
Where the home is worth more than the remaining balance, you pay the difference, which behaves like a down payment. On a home asking $500,000 with $450,000 left on the loan, that difference is $50,000.
If it’s more cash than you have, a second loan can cover the gap, and the blended rate across the two is typically still below what you’d get on the open market.
Will I need to pay private mortgage insurance after the assumption?
If the loan carries PMI and the balance is above the threshold, the buyer keeps paying it.
Will the interest rate on the assumed mortgage stay the same?
Yes. You take over the existing rate, and it holds for the remaining term of the loan.
Can I assume a mortgage if I have bad credit?
You still have to meet the VA or FHA requirements: a credit score of at least 580, with around 620 preferred, and a debt-to-income ratio under 50%.
Are there limits on how much I can borrow with a mortgage assumption?
The limit is the balance left on the existing mortgage, which can’t be increased or changed. Anything above that is cash or a second loan.
