Have been in real estate sales for over 40 years and have seen what's coming! :
If your purchase price is $500K...which is all too 'average' for a typical home in the Washington, D.C. region here's the difference in monthly payment compared to just 3 months ago.
Cash Down Payment = $100K
$400K MONTHLY Principle & Interest (P&I) at 2.500% is $1,580.48
$400K MONTHLY P&I at 6.375% is $2,495.48
That's an increase monthly of $915. and an annual increase of $10,980.
That's a Range Rover payment! Or...it's the combined car payments of husband and wife.

What happens next with the slowdown...
The Builders will have the upper hand and start offering "closing cost assistance" which will ultimately be used as pre-paid interest aka "POINTS" to BUY DOWN the interest rate.
In the above example, 4 points is $16K. So, you ditch the Tray Ceiling in the Owner's Suite or the Viking Stove in the Kitchen and use it to get that rate down.
Poor Sellers who have to compete with Builders in the neighborhoods are bleep-out-of-luck, and this crap will go on for YEARS!
Lots of Short Sales in the next year as the loss in market price eats into your equity that you borrowed on...so now you have TWO mortgages and are under water.
+++++++++++++++++++++++++++++++++
You're going to see lenders cut back on offering "equity lines of credit", or the guidelines will change to 70% vs. the current 80%.
