Zillow is way off on this one. Notice the recent pictures compared to the "street view". Recent changes include two new central air conditioning and heat pump units zoned separately for the upstairs and downstairs apartments. Ocean City is a summer rental vacation destination, Zillow rental estimates are for a year long rental of one apartment. This building has 3 rentals possibly generating $27,000 a season and that is a modest estimate. (common weekly rental of the large apartment starts at $1700 a week)
