I suppose one “benefit” of some HOAs is that they limit how many dogs can be in a property…If you knew the previous owner, maybe they don’t know they have dogs? Most insurance companies don’t like to insure pit bulls, let alone, 3 of them. The owner renting to them is waiting for a lawsuit to happen IMO.
I’d be very concerned about the dogs myself, especially with small children or even without small children, pitbulls scare me and are usually owned by crazy owners with self esteem issues who thinks a dog makes them tougher.
