Ball park each percent point (100 basis points) is worth about 13% of the home value. I.e. a $430K loan @ 3.75 is just about equal with a $380K @ 4.75, both are just under $2K per month.
The problem of course is any kind of markup for your home is going to have to come out of the buyers pocket in cash. The buyer pool that has the cash to pay you for the lower interest rate is pretty thin. Say home price go down or stay the same to reflect the high rates. The buyer can’t cash out equity on the lower monthly payment because the house isn’t worth the monthly payment at 3.75. It’s worth the monthly payment at 5 or whatever the interest rate is.
