Pay Down Cards or Preserve Cash Before Applying for a Mortgage?

I’m trying to plan credit-card payoffs before a mortgage application and would appreciate input on balancing utilization against cash reserves.

The key details I’m tracking are:

- Current limit and balance on each revolving account
- Statement-closing date, since the balance reported may differ from the balance shown on the payment due date
- Expected mortgage-application date
- Cash reserves that would remain after paying down the cards

For example, paying balances down before the statements close could reduce reported utilization and potentially improve pricing, but using too much cash might leave less available for the down payment, closing costs, prepaid expenses, repairs, and required reserves. Making only the minimum payment could preserve cash, but a higher reported balance may affect the credit profile reviewed by the lender.

How do lenders typically view this tradeoff? Is it generally safer to pay cards down aggressively before the relevant statement-closing dates, or to retain a larger reserve and accept some utilization temporarily? Also, how much lead time should borrowers allow for the lower balances to appear on credit reports before applying?
