Refreshing pre-approval letter

[Mark Miles]

When you're looking to buy a place, agents typically won't show you homes without a lending pre-approval (or proof of cash funds). In some cases, as an experienced investor, you're kind of looking but being patient until the right place comes along which might take 6 months or so. But lending pre-approvals typically expire after 30 days, and refreshing the pre-approval each time causes a hit to your credit score.

Do you keep refreshing the pre-approval letter every 30 days for your agent's benefit, or do you convince your agent to show you places without having a valid pre-approval letter?
