Some people may own just rent houses, some one or more small apartment complexes, and some own both. Some rent houses are actually duplexes, with an upstairs and a downstairs aprtment. Look into smaller apartment complexes, as they are more likely to be owned by an individual. We lived in apartments owned by a guy who had like a dozen complexes (none more than about 50 units each) and maybe half a dozen rent houses. We had 8 cats, a 75 pound dog, a bird living with us. The owner lived in the same complex we did, so he definitely knew about them.Thanks for the responses guys. When you say privately owned rental, you mean a house right? Isn't it generally a lot more expensive to rent a house vs an apartment?
