Purchasing a property with tenants in place

[Kole Kingslien]

Hello everyone! just had some quick questions. I am close to purchasing my first 4 unit property which I will live in, and there are already tenants in place, does anyone have advice and resources for inheriting tenants, how to start switching them to my policies, adjust rents, and so on? Also I am very young (22), and worried about being resented/not being treated with respect. the place is in a decent, but low income area, if that makes a difference. Any advice and resources is appreciated, thanks!
