Should I only communicate with my agent when house-hunting, or also update my lawyer and lender?

During the search, your agent carries the communication. The lender and attorney step in when an offer gets close. Your lender and, in attorney-review states, your attorney don't have much to do until you're ready to make an offer or you go into escrow. You don't need to email everyone every time you tour a house. One wrinkle on the pre-approval side: some agents use a single blanket pre-approval letter for every offer, while our own preference is a pre-approval package tailored to the specific property, which makes a more professional, competitive presentation to the listing side. Worth asking your agent which approach they take. On the lender relationship, the rhythm looks like this: - Actively touring homes: expect a check-in from your loan officer roughly weekly, mostly to keep your file current and ready for a fast offer. - Pre-approved but not yet actively searching: lighter, periodic contact, perhaps aligned to a target month you've mentioned. Beyond that, you only need to proactively update your lender when something changes on your end (new job, new debt, a large deposit) or you need something specific from them. Keep the agent close during the hunt, and loop in the lender when an offer is near.
