Housing: Lenders recoil from jumbo mortgages that back pricier homes

Lenders are losing their appetite for originating mortgages on pricier homes.

The spread between rates for jumbo mortgages, which are too big for government backing, and rates on those guaranteed by Fannie Mae and Freddie Mac shrunk as much as 11 basis points in mid-May, an indication that banks no longer see jumbos as an attractive investment. That spread was as wide as 64 basis points in November and now sits at 13 basis points, according to the Mortgage Bankers Association.

The narrowing follows the sudden regional banking crisis this year and "heightened concerns about liquidity," MBA Deputy Chief Economist Joel Kan said. Experts expect these conditions to continue into next year, a hindrance for buyers of higher-priced homes.

“On the securitization side of things, investors are dealing with massive extension risk,” Jeremy Collett, executive director of capital markets for Guaranteed Rate, told Yahoo Finance.

“That basically means loan payoffs are going to be really slow as borrowers who took out mortgages with 2%-3% rates in 2020 and 2021 aren’t likely to pay off anytime soon. So those bonds now have a much longer duration, preventing investors from getting their money back to reinvest at today’s higher rates,” Collett said.

During the pandemic, borrowers of jumbo mortgages were getting a “phenomenal benefit” on rates versus what are known as conforming loans that are purchased by Fannie Mae and Freddie Mac, according to Mike Fratantoni, chief economist at Mortgage Bankers Association.

“Before the pandemic, it was typical for jumbo mortgage rates to be just a small bit lower than conforming rates and last year [those rates] were a half point lower in many cases,” Fratantoni told Yahoo Finance in a phone interview.

Now the average 30-year fixed rate conforming came in at 6.91% for the week ending May 26, according to the latest data from the Mortgage Bankers Association. The average contract interest rate for 30-year fixed-rate mortgages with jumbo loan balances above $726,000 was 6.78%, or just 13 basis points lower.

Weakened demand follows recent distress in the banking sector, which drove First Republic (FRC) out of business as regulators seized the west coast regional lender last month and sold a bulk of its operations to JPMorgan Chase (JPM), marking the largest bank failure since the Great Financial Crisis.

One of the causes of First Republic’s troubles was a strategy to entice wealthy clients with bigger mortgages by offering sweet terms, Bloomberg reported.

Executives at the regional lender offered interest-only mortgages to wealthy homebuyers and investors, where the borrowers didn’t have to pay back any principal for the first decade of the loan.
