Thirty-year fixed, standard amortization. Taxes, insurance, HOA and mortgage insurance are left out on purpose: they do not change with the rate, and this page is about what the rate changes. The highlighted row is the latest Freddie Mac weekly average, updated when the survey prints.

How to read it

The first table

Price fixed, payment moves

Every row is the same loan. The only thing changing is the rate. This is the table people feel: the house they were looking at in the spring costs more every month now.

The second table

Payment fixed, house moves

Hold the monthly number still and each rate buys a different price. Per full point of rate, the same payment buys roughly a tenth less loan. That is the number that quietly re-sorts which houses are on your list.

Not in this estimate

Taxes, insurance, HOA, mortgage insurance

All real, none rate-sensitive, and taxes vary by town far more than by rate. Move-Up Math carries taxes and insurance; use it once you have a town in mind.

Not a forecast

Five scenarios, no prediction

The ladder brackets where rates have been this year. It is not a guess about where they go next, and it is not a loan offer or an approval. Your lender prices your file.

Why it matters this autumn

A higher rate has not meant a cheaper house

Demand cooled when rates moved, but new listings thinned at almost the same pace, so the discounts people were waiting for have not shown up in the national numbers. That makes the second table the honest version of “wait for a better rate”: the payment you can carry sets the house you can buy, and waiting only helps if the rate falls more than the competition returns.

This is a planning estimate from the figures you enter and standard 30-year amortization. It is not a loan offer, a rate quote, an approval, or financial advice. Rates shown other than the highlighted Freddie Mac average are scenarios, not quotes.

Selling to buy?

Move-Up Math takes the equity from a sale and shows the new monthly number with taxes and insurance in it. It opens at today’s rate.
