Equity credit card payoff and mortgage rate

[Anonymous]

We have been approved for a mortgage and we found a builder who is starting our house. We have a house we currently live in and we are selling it. We will close on the new build about a month before it is complete. We should have around $30,000 equity once it sells. We planned on using $10,000 equity to pay off all our credit cards. My question is concerning getting the lowest rate. So, how long after our credit cards are paid off does it affect your score?

A few days after the statement cut you should see the score increase based on your utiization.  If were say at 70% utilizatio on that card and you paid it down to < 10% you would get a decent. score increase.  If you were at say 30% utilization on a card and pay it down to 10% then not near as much.. Anyways about 3-4 days after statement cuts will it report to the CRA's with a lower balance and an increased score typically.. Some creditors are a bit different, but generally holds true.
