Con artists prey on renters by leasing properties they don't own. Renters are often surprised to see police at their door only days after moving in. Renters must then struggle to find somewhere new to live with no notice and a lost security deposit.
Many landlords are underwater and do not continue to paying the mortgage. Often this does not deter them from collecting rent. When this happens a tenant is still legally obligated to pay the rent even though they will evetually be evicted in foreclosure.
Live with peace of mind by knowing you are not being ripped off by a landlord or con artist.
