Broker info & key considerations To confirm
- Excluded from active opportunities. The exact MLS removal date is unavailable; the portal reports a 2022 sale, not a newly verified sale. Older six-bedroom listing scope also differs from the portal’s four-bedroom public record.
- Lease collections, expenses, lawful unit count and current availability remain unverified.
- Confirm rental licensing and wind/flood coverage for the intended use.
