The property owner's raising their rent like that, well actually is a huge gamble on their part, but it will either break them if their good tenant's move out or it will save their property values and investment's by keeping the living quality, and the area it all exist in safe, so upping the scale of living quality in the area is never a bad thing, but it definitely is a gamble on their part. Depends on how the area in which the investment exist in is trending that should determine the stability of the investment property, and how that property is to be managed in order to protect the investment property value and it's safety.I've owned 3 houses in my life. Soon I'll be coming into a lot of money, and I'll buy a whole estate with 50+ acres. Your "choices" are stupid. And your refusal to condemn the ripoff landlords buying properties and raising rents 200%, tells me you're one of them. Disinterested, objective people are unlikely to say what you say.
