As an investor, you should be particular on what type of property you wanna buy. If it's a property that has got a lot of maintenance, you've gotta be very selective on what kind of tenant goes into the property.
If it's got a lot of woodwork, if it's got a lot of yard maintenance, if it's old, then the chances are that if you don't get a good tenant, it's gonna cost you a lot of money to maintain it. If you're an investor that is just, wants to have a tenant in there, not worry too much about the property, then you really want something low touch.
A unit, a townhouse, the less features, the less things can go wrong with the property.
