We’re proud to announce the release of the Assumable Atlas, our public, hyper-local market view of assumable mortgages across the US, built on top of our national database of assumable loan data. All told, we sit at around 10.6M homes with an assumable loan that aren’t for sale, plus around 120,000 that are on the market at any given time. You really can see everything.

Invisible Listings, Invisible Data

You’re probably reading a lot about how a 30-year fixed rate above 7% has blown up the real estate market. Indeed, mainstream coverage about the effects of high rates is pretty depressing.

“…Buyers are staying on the sidelines…”

“…Sellers are reluctant to list their homes because nothing is getting any attention…”

“…Agents are having their worst year in decades…”

However, there’s a story hidden in the market that isn’t being told. I’ve been working on assumable loans for over two years now, and I didn’t realize that Ewa Beach in Hawaii has some of the highest potential monthly P&I savings in the country at $895 a month, at the same cash to close. Or that Chula Vista, CA (right in our backyard) has one of the best average assumable mortgage rates in the country at 3.97%!

With about one in ten homes on the market having an assumable loan, there are deals out there right now that could save a new buyer hundreds of dollars in P&I payments every month, at the same cash to close. This is often the difference between getting the home of your dreams or waiting on the sidelines for the Fed to make a move.

However, almost none of these great deals are marketed publicly. Assumable details usually don’t make it into the public remarks, so you won’t find them on your favorite real estate websites, and your agent won’t know about them. They’re functionally invisible even if you know what to look for.

With no clear way to find and quantify the assumable opportunity, it’s no wonder that coverage of assumable listings is sparse. There’s never been a way to clearly dive into the data, until now.

State by State, City by City

Your own personal census to assumable inventory.

The Assumable Atlas is your own personal census to assumable inventory in the states, cities, and ZIPs that you care about. We break down where the inventory is, the average rate and rate band distributions, as well as FHA and VA share, showing you average P&I savings against the market rate at the same cash to close. We do this across 10.7 million assumable loans down to the ZIP code level, even in markets where we don’t have active listing data.

The Assumable Atlas calculator for San Antonio, Texas, comparing a 4.64% assumable loan at $1,441 a month against a new 30-year fixed at 7.22% and $1,738 a month, with $35,675 saved over the first ten years at the same cash to close.
See how much you could save on the average loan anywhere.

In markets where we have listing coverage through our brokerage or MLS partnerships, we dive even deeper and show you the percentage of on-market homes with assumable loans and give you access to our assumable loan calculator that shows you what it might look like to take over someone else’s mortgage.

The data showcases military towns with high VA concentrations, or where first time homebuyers are setting down roots with strong FHA coverage. I can go on and on, but dive into the data yourself. It’s a fascinating look at a time when the front pages are covering the doom and gloom of the market.

Your Free Assumable Resource

Let us know if you want to talk about the data one on one.

As far as we can tell, there’s nothing like this on the market today. RetroRate worked hard to create the most complete and accurate database of assumable loan intelligence out there, because we genuinely want more homebuyers to find great deals and get into homes. We draw from a multitude of data sources like public property records, historical and current interest rate data, unstructured MLS information and more. Our system automatically cleans up obvious errors, patches holes and scores the result to help you find the best loans out there.

Our Atlas is free to use, no ads, no listing solicitations. We only ask that if you use it in your coverage you credit our name, and send us some of your leftover Halloween candy.

Of course if you’re working with an agent equipped with RetroRate technology, you could already be finding these deals hiding in plain sight.
