Is Home Insurance Invalid if I Don't Update My Address?
A policy covers the address you listed. Insure your new address before closing so coverage actually applies.

Your policy is written for the address on the declarations page, so the new house needs its own policy before closing, not an update to an old one. If you're currently renting or own a different home, that policy won't transfer or extend automatically. What matters for the lender is a binder, a short document proving coverage starts on the closing date, with dwelling coverage at or above the rebuild cost they require. Get the new address right on that binder, since a mismatch can delay signing.
Get the new address right before you compare prices
The binder your lender needs is tied to the right address and the right rebuild cost, not the lowest number. Comparing policies now means you can check both before closing day arrives.
What if I move again after this policy starts?
Once the new house closes and the policy is active, it still only covers that one address printed on the declarations page. If you sell this house in a few years and buy another, the same rule applies. The old policy doesn't follow you, and a new policy needs to be written for wherever you're moving next.
Most insurers let you update an address mid-term if you're not changing houses, just double-checking the records are right, for example if there was a typo at setup or the street was renamed. That's a quick fix, usually a phone call or a form. Moving to a different house entirely is not an update. It's a new policy, because the rebuild cost, the construction, the location and the risks are all different.
If you're buying this house with a plan to rent it out later, or to use it as a second home, tell whoever sets up the policy now. A standard homeowners policy is priced and written assuming you live there as your primary residence. Renting it out or leaving it vacant for long stretches can affect what's actually covered, and that's worth sorting out at the start rather than after something happens.
None of this affects what you need to do before closing. The task right now is getting the new address correct on the binder and matching the dwelling coverage to what the lender requires. What happens if you move again, or change how you use the house, is a question for that day, not this one.
Does the policy start the day I close, not before
A policy takes effect on the date written into it, usually the closing date, not the day you sign the application. If closing gets pushed back a week, the binder and the start date typically need to move with it. Tell whoever is setting up the policy as soon as the closing date changes. A policy that starts before you own the house, or one that's still pending when you actually close, doesn't do what the lender needs it to do.
If there's a gap between closing and moving in, the house is still covered under the new policy as long as it's listed as the address on the declarations page. You don't have to be living there yet. What matters is ownership and the address matching, not occupancy on day one. Plenty of buyers close on a house and move in weeks later, and the policy holds through that gap.
Selling the house years from now works the same way in reverse. Coverage ends when the policy is cancelled, which usually happens around the closing date of the sale. Whatever you buy next needs its own policy written for that address. There's no such thing as a policy that follows you from house to house. Each one is tied to a specific property with its own rebuild cost, construction and risks, so a new address always means a new policy, not a transfer.
None of this changes what needs to happen before this closing. Get the address right on the binder, match the dwelling coverage to what the lender requires, and confirm the start date lines up with closing day. Questions about moving again, renting the place out, or what happens years down the line are worth knowing about, but they don't affect what has to be done now.
Before closing day
Check that the binder shows the new address exactly as it appears on the deed, the dwelling coverage meets what the lender requires, and the start date matches your closing date.
