Insurance when you buy a home

Most buyers think about homeowners insurance somewhere between the mortgage approval and the closing date, as a box the lender needs ticked.

By then several decisions have already been made for you. The property you chose has an insurance profile — its location, its roof, its plumbing, its claims history — and that profile was fixed before you signed anything.

The III’s advice is unambiguous about the timing: “Don’t wait until the last minute to think about homeowners insurance,” and get “an estimate of the premium” before finalising your purchase offer.

What about the house changes the insurance

The III lists the property characteristics that matter, and they are not the ones most buyers are evaluating on a viewing.

Distance to a fire service. Houses “located near highly rated, permanently staffed fire” departments “usually cost less to insure.” This is one of the larger single factors and it is completely invisible on a listing.

Proximity to a coast. Coastal properties cost more, and in some markets a buyer “may need to purchase insurance through a state-run insurance program” — meaning the standard market may not write it at all.

The condition of the plumbing and electrical systems. Outdated or poorly maintained systems cost more to insure and, in some cases, make a property difficult to place.

The roof. “A new roof matters to insurers,” and roofs in fire- or hail-resistant materials may attract a discount. A roof near the end of its life can be a condition of coverage rather than a pricing detail.

How it was built. Homes “constructed to meet modern engineering-based building codes are likely to better withstand natural disasters” — which underwriters price accordingly.

Age and finish. Older homes with “ornate features like plaster walls, ceiling molding and wooden floors may be costly to replace,” which raises the replacement cost figure the policy has to carry.

The report almost nobody asks for

There is a document that tells you what has gone wrong at the address, and buyers rarely request it.

The III recommends obtaining a loss history report — C.L.U.E. or A-PLUS — before bidding, alongside hiring “a credentialed home inspector” to identify structural concerns and verify that past repairs were properly completed.

The report “shows the type of loss on the home, the date of the loss and the amount and status of each claim,” going “back five years.”

Two reasons this matters more than it sounds.

It tells you about the house. Three water losses in five years is a fact about the plumbing, the grading or the roof — and it is a fact the seller may not volunteer.

It follows the property. The next insurer sees it too. A property with a claims history is priced on that history regardless of who is living there.

The seller can request the report. Asking them to is a normal part of due diligence and the request itself is informative.

What the lender requires is not what you need

Your mortgage lender will require homeowners insurance, and in a designated high-risk flood zone, flood insurance too.

Those requirements exist to protect the lender’s collateral. They are not an assessment of your exposure, and treating them as one produces two predictable errors.

The first is insuring the building for the loan amount rather than what it costs to rebuild. Those are different numbers, and the gap between them is the buyer’s problem, not the lender’s.

The second is concluding that no flood requirement means no flood risk. The III notes that flood and earthquake both require “separate” coverage since they are excluded from standard policies — flood through the federal programme and specialty insurers, earthquake generally “from private insurers as an endorsement to a homeowners policy.”

Flood maps describe probability. Being outside a mapped zone means your lender is not requiring it. It does not mean water cannot reach you.

The sequence that works

Roughly in this order.

While you are still viewing houses. Ask your agent for a rough premium estimate on the addresses you are serious about. A coastal property, an older home, or one with a claims history can cost meaningfully more than a similar house a few miles away, and that difference belongs in your budget before your offer, not after.

Once you are under contract. Get the loss history report. Get the home inspection. Get a firm quote based on what the inspection found.

Before closing. Bind coverage effective on the closing date. Confirm the replacement cost figure is what it should be rather than what a default calculation produced. Ask about flood and, in relevant regions, earthquake, separately and explicitly.

After you move in. Do a contents inventory while the boxes are still recent. It is the only time this task is ever easy.

The renovation point

One thing that catches new owners in the first two years.

The III’s list of life changes that should trigger a review includes: “Have you done extensive renovations on your home?” — because renovations change what it costs to rebuild, and a policy written against the pre-renovation house will not respond to the post-renovation one.

New buyers renovate more than anyone. Tell your agent when you do.

What to do

Ask for a premium estimate before your offer is final — this is the single highest-value item on the list and it costs one phone call.

Request the loss history report on the property, and read it against the inspection report.

Get a flood quote whatever the zone says, and ask specifically about wind or hurricane deductibles if you are anywhere they apply.

Insure to rebuild cost, not to the loan or the purchase price, and ask how that figure was calculated.

And when you renovate, say so. Most underinsured houses got that way one improvement at a time.
