Should I Buy a House in FEMA Zone AE?
It can work, but Zone AE requires flood insurance from your lender, a separate policy adding to your cost.

Why the lender requires it
Zone AE is a high-risk flood area on FEMA's map. If the house has a mortgage, federal law requires the lender to make flood insurance a condition of the loan. This isn't optional and isn't tied to whether the area has flooded before.
What your homeowners policy skips
Your homeowners policy covers fire, wind, theft and similar damage to the house, but it excludes flood water entirely. In Zone AE, that gap is the main risk, so the flood policy isn't extra protection, it's the piece covering the most likely cause of damage.
The two premiums together
Plan on two separate bills. One is for the homeowners policy. The other is for flood coverage through the National Flood Insurance Program or a private insurer, and in Zone AE that cost varies with the house's elevation relative to the base flood level shown on the flood map.
Getting both bound before closing
Your lender needs proof of both policies, not just homeowners, before closing can happen. Flood policies can take longer to underwrite than homeowners ones, so start that application early enough that an elevation certificate or survey doesn't hold up your closing date.
Two policies, one closing date

What else changes once the house sits in Zone AE
An elevation certificate is the document that decides a lot of this. It shows how high the lowest floor sits compared to the base flood elevation on the FEMA map, and that gap drives the flood premium more than almost anything else about the house. If the seller already has one, ask for it before you get too far into the process. If not, you may need to pay a surveyor to produce one, and in some markets that takes a few weeks to schedule, not a few days.
Zone AE isn't one fixed price tier. A house with its lowest floor several feet above the base flood elevation can cost much less to insure for flood than a house at or below it, even on the same street. This is part of why two homes that look similar on a listing site can carry very different insurance costs. It's worth asking the seller's agent whether the current owner has a flood policy and what it costs, as a starting point, though the policy won't necessarily transfer at the same rate when the house changes hands.
Some houses in Zone AE were built or substantially renovated after the flood maps were drawn, and were required to meet elevation rules at the time. Others predate those rules and sit lower relative to the base flood elevation. Neither fact shows up on a typical listing. A home inspector isn't the right person to ask about this. The elevation certificate and the flood zone determination are the documents that answer it, and your lender or insurance agent can help you get the right one for this specific address.
Dwelling coverage on the homeowners side still matters here too. That's the amount the policy pays to rebuild the house, and it's based on construction cost, not the sale price or the mortgage amount. A house in a flood zone sometimes carries higher rebuilding costs if local rules require it to be rebuilt at a higher elevation after a covered loss, so ask whether your state or county has an ordinance like this and whether it changes what dwelling coverage you need to carry.
What a non-renewal or claim history on the house can mean
Ask the seller whether the house has ever filed a flood claim, and ask the seller's agent to check the property's claims history if they have access to it. A house with prior flood claims can carry a different premium than one without, even at the same elevation, because some flood policies are priced in part on the building's own claim record rather than the zone alone. This is separate from the homeowners claims history that a standard insurer might ask about, and it's worth asking for both.
If the house was substantially damaged by a past flood and repaired, some local rules require it to be brought up to current elevation standards before it can be reoccupied or resold. Whether that happened here affects both what the flood policy costs now and what it might cost to rebuild if it floods again. County building records, not the listing, are where this shows up. A title search sometimes turns up permits related to flood repairs, so it's worth asking the title company directly rather than assuming the standard search covers it.
Some lenders also ask for a Letter of Map Amendment or a Letter of Map Revision if the owner has ever challenged the property's flood zone designation with FEMA. If one exists for this address, it can change what zone the house is actually rated in for insurance purposes, even though the public flood map still shows Zone AE. This is uncommon, but it's a quick thing to ask about, since it can move the flood premium by a meaningful amount if it applies.
None of this changes whether the lender requires flood coverage. It changes what that coverage costs and whether the number from a quote today will hold once underwriting looks closely at the building's history and elevation. Getting these documents together before the quote stage, rather than after, is what keeps the number from moving late in the process.
Before you request quotes
Ask the seller for the elevation certificate now. It sets the flood premium, and without it the homeowners quote alone won't tell you what this house actually costs to insure before closing.
