The meme specifies Mortgage which means they also don't have any money. They obtained a loan that they will be paying back for 15 to 30 years, at which point the property will deteriorate to a much lower value if any at all. If they sell the properties then they will owe depreciation recapture which works similar to a capital gains tax, as if it were additional income on top of the actual capital gains tax on the sale of the property itself. Plus closing costs to realtors.
