About RetroRate VHS: View Home Savings
Don't get a new loan. Assume a better one.
Six million U.S. homes come with a mortgage you can legally take over at the original 2-4% rate. The catch? Zillow, Redfin, Realtor.com, and Compass don't tell you which ones.
RetroRate VHS is a free Chrome extension that fixes that. Browse the real estate sites you already use. We highlight every listing with an assumable mortgage — automatically — and show you the rate, monthly savings, and lifetime interest you'd save vs. a new loan at today's rates.
⭐ Built for buyers priced out by today's rates ⭐
If you've watched friends lock in 2.75% mortgages while you're staring down 7%, this extension is for you. The 3% rate era isn't over. Those mortgages are sitting on millions of homes that are for sale right now. RetroRate makes them visible.
🏠 How it works
1. Install RetroRate VHS (free, takes 10 seconds)
2. Browse Zillow, Redfin, Realtor.com or Compass like normal
3. Look for the RetroRate overlay, it appears automatically on every listing with an assumable loan, showing you the rate, monthly savings, and total interest you'd save
That's it. No new search portal. No subscription. No catch.
📊 What you'll see on every assumable listing
✓ The exact assumable interest rate
✓ Monthly payment vs. a new mortgage at today's rates
✓ Total lifetime interest saved
✓ Down payment / equity gap requirements
✓ Loan type (FHA, VA)
✓ Nearby homes with even better rates
📍 Nationwide coverage, all 50 states
Every state. Every metro. Every FHA and VA loan that qualifies for assumption. We're the only assumable mortgage tool with full nationwide coverage.
❓ Common questions
"What's an assumable mortgage?"
A loan you can legally take over from the seller at their original interest rate. FHA and VA loans qualify by federal law
"Do I have to be a veteran to assume a VA loan?"
No. Anyone can assume a VA loan. This is one of the most underused facts in real estate.
"Is this affiliated with Zillow / Redfin / Realtor.com / Compass?"
No. We're an independent tool that overlays our own data onto pages from those sites. We don't extract or scrape listing content from them.
"How much can I actually save?"
Buyers typically save $500-$1,500 per month vs. a new mortgage at today's rates. Over 30 years, that's often $200,000+ in interest.
"Is the extension really free?" Yes. No paid tier. No subscription.
🔒 Privacy The RetroRate overlay is visible at all times when active on supported pages, so you always know when the extension is working. We don't collect personally identifying information unless you provide it. We don't sell user data.

A Note about displayed rates: We typically use ~7% as the prevailing “prime” rate in our calculations, but that fluctuates multiple times a day. Sample assumable calculations shown on RetroRate are created using interest rates that reflect loans originated from several years ago. Estimated monthly payments only indicate P&I and do not include taxes & insurance which will make them higher.
RetroRate does not originate loans, determine or extend credit, or engage in lending or brokering of home loans. The original lender or servicer who holds the mortgage being assumed handles qualification and approvals of new buyers, usually by working with the VA and FHA. The original lender or servicer makes the final decision to extend credit.
