Advertised rents less than mortgage

[Katie Hendrixson]

Has anyone been running across multifamily properties listed for sale, with rents included, that wouldn't even cover the mortgage (https://www.zillow.com/homes/for_sale/house,condo,apartment_duplex,townhouse_type/12332683_zpid/pricea_sort/37.623426,-77.458827,37.593713,-77.504961_rect/14_zm/0_mmm/)? Like, even after 20% down? Is this normal, historically, or just a reflection of the bubble we're in? I know asking price isn't sale price, but it seems like I've been running across several of these, and clearly I'm missing something big. Thank you!
