It’s actually half off.
30-year mortgage rates hit 3.75% which is exactly half of their long term average.
Rates have averaged 7.5% over the last 40 years so today buyers are getting half of that rate.
The “sale” on mortgage rates creates a significant savings in monthly payment because of the 1%/10% rule.
For every 1% change in interest rate, the monthly payment will change roughly 10%.
So when rates go up to 4.75%, a buyer’s payment will be 10% higher.
For example, the principal and interest payment on a $400,000 home with a 20% down payment at today’s rates is $1,482.
If rates were 1% higher, the payments jump up to $1,669.
