Broker info & key considerations To confirm
- One unit is advertised vacant, so the historical $69,000 is not a current whole-property rent roll.
- Obtain elevation, roof, flood/wind coverage and legal-use records.
- Listing availability, legal units, lease collections and operating costs require independent confirmation.
