Quite likely. 

Although the savings in monthly payment reaches diminishing returns at some point. Nearly doubling the term (50 vs 30) only produces a ~13% reduction in monthly payment. 



My expectation is that these will just become the norm and 30-year mortgages will be similarly niche as 15-years are today.

Trump's 50-Year Mortgage Will Bring More Inflation and Corporate Bailouts

True. 

The old adage of real estate is very true: Location, location, location. 

I learned that. The house I owned from age 25-36 was in a poor location but it was a low price. I made almost nothing on that after accounting for property tax and repairs I did over those years. Maybe I netted 1% annually. 

My current house, in a very high demand location, is growing at 5-6% annually. 

My point on that is those who will likely need a 50 yr loan will not be buying "premium location" houses on average.
