Monthly mortgage payments are $600 more than five years ago

A dramatic cost surge over five years

American homeowners and buyers are feeling the full weight of how much more expensive it has become to finance a home. According to Yahoo Finance, the average monthly mortgage payment has risen from $1,525 in 2021 to $2,134 today — an increase of nearly $610 per month, or around $7,300 per year.

Two factors have driven this increase in tandem: rising home prices and an interest rate environment that never fully retreated after the central bank's tightening cycle. Thirty-year fixed-rate mortgages are currently priced between 6.47 and 6.625 percent APR, compared to well below three percent at the height of the pandemic boom.

Norwegian context: A familiar squeeze

Although the figures relate to the US, the underlying problem will resonate with Norwegian households. Norges Bank raised its policy rate to historically high levels in 2023–2024, and while rates have since been cut somewhat, mortgage costs remain significantly higher than they were five years ago. The Oslo Stock Exchange (OSEBX) and Norwegian real estate equities have both been sensitive to interest rate changes over the same period.

Crypto-backed mortgages: An expensive alternative

As traditional mortgages have become both costlier and harder to qualify for, so-called crypto-backed mortgages have attracted renewed attention — particularly among individuals with substantial digital assets but limited liquidity in the conventional sense.

The concept works by having the borrower pledge cryptocurrency such as Bitcoin or Ethereum as collateral for the mortgage, without selling the holdings. This allows the borrower to retain exposure to any future price appreciation while theoretically avoiding an immediate taxable event on gains.

However, the interest rates are considerably higher: the platform Milo.io quotes rates between 7 and 9 percent APR, while other providers such as Ledn operate at 9.25 to 11.49 percent. By comparison, traditional 30-year fixed-rate mortgages, as noted, sit at around 6.5 percent. Some analyses suggest that crypto-backed mortgages can cost up to 30 percent more per month than a conventional loan.

Regulatory developments in the US

The Federal Housing Finance Agency (FHFA) has recently asked Fannie Mae and Freddie Mac to explore whether crypto assets could be factored into mortgage applications — without requiring the holdings to be liquidated first. Fintech company Better and Coinbase recently launched a so-called tokenized mortgage under Fannie Mae standards, in which Bitcoin or USDC can be used as collateral for the down payment portion of a standard home loan.

Experts are divided. Housing and banking analyst Christopher Whalen described crypto-backed mortgages as "a really bad idea," pointing out that digital assets can lose 40 percent of their value within days. Financial regulation expert Sean Tuffy believes the product primarily benefits people who can already afford a home. On the other side, Cory Klippsten, CEO of Swan Bitcoin, argues that recognizing crypto wealth could help "asset-rich but cash-poor" individuals enter the housing market.

DeFi real estate: The future of home financing?

In parallel, decentralized finance (DeFi) is emerging as a potential infrastructure for real estate financing. Tokenization of real property — converting a property into digital shares on a blockchain — enables fractional ownership and faster transactions via smart contracts.

The market is still small, but growing rapidly. The value of tokenized real estate increased from $690 million in 2020 to $14.3 billion in 2021, according to available market data. Tokenized real estate funds are projected to reach one trillion dollars by 2035.

Platforms such as RealT and Propy are early examples of players already offering such products, but the industry has not yet matured enough from a regulatory standpoint to compete with traditional home financing at scale. Many DeFi lending protocols still require overcollateralization of 120–150 percent, which limits accessibility for most homebuyers.

The bottom line is that neither crypto-backed mortgages nor DeFi solutions currently represent a genuine mass-market alternative to the traditional mortgage — but the pressure of rising monthly costs could accelerate both product development and regulatory clarity in the period ahead.
