Episode Title: Want a 2.5% mortgage? Buy it.
Date: March 5, 2026
Hosts: Waylon Wong & Stephen Bissaha
Theme:
This episode explores the unique possibility of securing ultra-low mortgage rates—like the coveted 2.5% loans from the early 2020s—even in a high-rate world. The hosts explain how “assumable mortgages” let some buyers take over the seller’s low mortgage rate, discuss why this isn’t more common, and explore the policy debates and practical hurdles around making more mortgages assumable in the future.

Key Discussion Points & Insights

Nostalgia for Low Mortgage Rates

• Stephen opens with a “time travel” fantasy, wishing to return to 2021 for the low mortgage rates of that era.
• Notable Quote:

  “One reason I want to go back is so I could get a mortgage. Mortgage rates at the time were crazy low, like less than 3%.”
  — Stephen Bissaha (00:55)

What Is an Assumable Mortgage?

• Home buyers can sometimes take over (“assume”) a seller’s old, ultra-low mortgage rate.
• Common with government-backed loans (VA & FHA), but rare in conventional mortgages.
• Notable Quote:

  “Brendan saw in the listing the option to buy the home and get a 2 1/2% mortgage rate.”
  — Stephen Bissaha (03:01)

Real-World Example: Brendan Burroughs’s Story

• In 2024, Brendan Burroughs in Florida finds a home with an assumable 2.5% mortgage.
• Describes a long, frustrating process with the lender, but ultimately succeeds thanks to a large down payment funded by prior investments.
• Notable Quote:

  “We’re just sitting there waiting for a phone call back. Ten days go by, a month goes by, I’m hearing nothing.”
  — Brendan Burroughs (04:38)

Scale of Opportunity

• About 6 million homes (7% of U.S. mortgages) have assumable loans below 5%.
• Sellers must give up their low-rate mortgage; enticing buyers by including this in home listings.

Barriers to Assumable Mortgages

1. Administrative Delays

• Although legally creditors should process assumptions within 45 days, it often drags on for months.
• A cottage industry exists to help buyers navigate the process.
• Advocacy for better enforcement in Congress.

2. Large Down Payments Needed

• Housing prices have soared—original mortgage balances are far lower than today’s prices.
• Buyers must cover the gap, often over $100,000.
• Notable Quote:

  “I had to put down $105,000… that is a lot for a first time home buyer.”
  — Brendan Burroughs (05:21)

3. Need for Cash-Heavy Buyers

• Brendan’s case only worked due to personal stock market gains, a rare situation.
• Not feasible for most first-time buyers.

Policy and Market Implications

• The Trump administration is investigating expanding assumable mortgages for Fannie Mae/Freddie Mac loans.

• Industry experts, like Lori Goodman from the Urban Institute, say that only future mortgages can have new terms—not existing ones.

• Mortgage investors resist because assumptions cut into redeployment of capital at higher rates.

• Quote:

  “You can’t change an existing contract unless both sides agree.”
  — Lori Goodman (06:58)

Potential Downsides

• Expanding assumability might push banks to charge higher rates upfront to compensate for lost future returns.
• Quote:

  “If you made the mortgage assumable… I would probably charge you more for that mortgage at the very beginning.”
  — Lori Goodman (07:45)

• Could mean higher rates on new loans, possible return to double-digit rates if market conditions worsen.

Who Stands to Benefit?

• Assumable mortgages could, in theory, free up much-needed “starter homes.”
• Cash-rich buyers, not typical first-time buyers, usually benefit.
• Quote:

  “We want to free up starter homes… for young families who are the last people that can come up with extra $200,000 in cash.”
  — Lori Goodman (08:30)

• Brendan saves tremendously:

  “My coworker… paid like $3,200 a month. And I said, yo, my mortgage. Literally half that.”
  — Brendan Burroughs (08:56)

Notable Quotes & Memorable Moments

• “We were just celebrating last week when mortgage rates fell below 6%.”
  — Waylon Wong (01:06)
• “Listing a home with a 2 1/2% mortgage rate, that is a big selling point.”
  — Stephen Bissaha (03:58)
• “Brendan… should probably be hosting this show.”
  — Stephen Bissaha (05:51)
• “Without that low rate, he probably would have spent two more years Zillow surfing at the in-laws.”
  — Stephen Bissaha (09:01)

Summary

Assumable mortgages—where buyers can take over the seller’s existing home loan and its rate—hold headline appeal but come with major caveats. The process is complex, slow, and often requires huge sums of cash upfront due to rising home prices. Government and industry leaders are debating whether to broaden assumability but face structural barriers, and any major change could mean higher overall interest rates. For now, the lucky few—like Brendan Burroughs—who can snag an assumable mortgage can save huge, but the tool remains out of reach for most aspiring homeowners.
