In a social put up on Saturday, President Trump floated the thought of a 50-year mortgage to spice up housing affordability, however the thought obtained a frosty reception on-line. One motive is that stretching the mortgage time period out that lengthy finally ends up costing far more in curiosity over the lifetime of the mortgage whereas solely shaving a number of hundred {dollars} off the month-to-month fee.
You additionally should think about the next mortgage fee than what you get with a 30-year mounted mortgage.
On Sunday, FHFA Director Invoice Pulte responded to the backlash with this post: “We hear you. We’re laser centered on guaranteeing the American Dream for YOUNG PEOPLE and that may solely occur on the financial degree of homebuying. A 50 12 months Mortgage is solely a possible weapon in a WIDE arsenal of options that we’re growing proper now. STAY TUNED!”
What’s the rate of interest on a 50-year mortgage?
So how a lot would a 50-year mortgage find yourself costing homebuyers? To reply that, we have now to contemplate the mortgage fee and the curiosity paid over the lifetime of the mortgage, and examine that to the advantage of a decrease month-to-month fee.
HousingWire Lead Analyst Logan Mohtashami outlined what the speed on a 50-year mortgage might seem like.
“Historically, the longer the amortization, the upper the mortgage fee,” stated Mohtashami. “Wanting on the distinction between a 20-year mortgage and a 30-year mortgage, the best-case state of affairs for a government-backed 50-year mortgage product would put charges most certainly between 0.42% to 0.57% greater than a 30-year mounted mortgage.
“Utilizing the 30-year mounted mortgage fee on the shut on Friday of 6.32%, you could possibly be mortgage charges of 6.74%-6.89% for a 50-year mortgage. It may very well be greater than that, however that’s the best-case state of affairs I see,” Mohtashami stated.
Taking that 6.32% for the 30-year and utilizing 6.80% for the 50-year, listed here are the funds based on the Fannie Mae mortgage loan calculator, at completely different value factors. That is solely calculating the principal and curiosity fee, as the remainder of the month-to-month fee — taxes and insurance coverage — differ an excessive amount of by location to offer a priceless common.
Beneath is one other view of the distinction in curiosity funds over the lifetime of the mortgage between the 2 mortgage phrases.

Regulatory challenges might imply greater charges
The curiosity distinction may very well be a lot starker relying on how a 50-year mortgage is structured for the market. After the nice monetary disaster, Congress handed the Dodd-Frank Wall Street Consumer Protection Act which stipulated the sorts of mortgages that Fannie Mae and Freddie Mac would purchase on the secondary market.
“A 50-year mortgage wouldn’t violate the Dodd-Frank Act outright, however it will not qualify as a Qualified Mortgage (QM) below the Act’s Means-to-Repay (ATR) guidelines,” stated James Brody, managing associate at Brody Gapp LLP. “Present laws cap QM loans at a 30-year time period, so any mortgage exceeding that period falls exterior the usual.”
“In apply, this implies a 50-year mortgage might solely be originated as a non-QM mortgage, which lacks the authorized secure harbor protections of a QM and sometimes carries greater rates of interest. Until the ATR guidelines are amended to incorporate 50-year phrases, lenders can be unable to promote these loans to the GSEs (Fannie Mae and Freddie Mac), severely limiting the product’s liquidity.
“Briefly, whereas not unlawful, a 50-year mortgage has very restricted salability within the secondary market below the present Dodd-Frank framework,” Brody stated.
