Buyer research checklist
Items worth confirming for 111 Avenue D #2, chosen from what the record shows. This is general guidance, not advice about this specific property.
- New construction: get the builder's warranty terms and the certificate of occupancy in writing, and ask which finishes shown are upgrades.
- The listing reports no HOA: confirm with the county record that no deed restrictions or mandatory association apply to this parcel.
- Look up the parcel on FEMA's Flood Map Service Center and confirm with your insurer whether flood insurance is required.
- Get a homeowners insurance quote for this specific address in Monroe County; a wind-mitigation inspection and, on older homes, a four-point inspection can change the premium.
- Private pool: confirm the barrier or alarm meets the state residential pool safety code and ask for pump, heater, and resurfacing records.
- Waterfront: confirm seawall or dock condition and permits, and ask who owns and maintains the shoreline.
- Confirm square footage and room dimensions independently.
- Order a survey to confirm lot boundaries and easements.
- Review permit history with the county.
- Property taxes: the estimate on this page (about $30,440/yr) assumes reassessment at the list price; the seller's homestead cap does not transfer, so their current bill is not a guide.
- Confirm school zoning directly with the district.

What community is 111 Avenue D #2 in?
111 Avenue D #2 is in Coco Plum Beach (54.5) in Marathon, Monroe County. The community section on this page shows recent closed sales, days on market, and active inventory for Coco Plum Beach (54.5) from the same MLS data.
Does 111 Avenue D #2 have an HOA?

Why might property taxes on 111 Avenue D #2 differ from the current owner's?
The estimate on this page (about $30,440 per year) assumes reassessment at the list price.

Any tax figure shown here is an estimate, not the actual bill — confirm with the county property appraiser and tax collector.

A flood designation has not been verified for this address. Look up the parcel on FEMA's Flood Map Service Center (msc.fema.gov) and confirm with your insurer.
