If you move out of the city you must register a property rep with the city that will be contacted in case of emergency.

inherited" tenants like yours are probably waiting to hear from you, so send out contact emergency info and have them respond and include with next rent payment a updated contact sheet,, I'd make an appointment to tour inside of each unit with condition sheet,, the condition from your date of ownership is now what you use for condition move out.. so once that's completed you now know which unit would be tops on your list to rehab and offer an early out to.. if that's a consideration.. you can of course let all tenants know the rent will increase to $$$ when their lease is up and you are accepting 30 or 60 day vacate notices early, they'll be prepared.

My mom wants to partner with me and buy property together since she has perfect credit and a better chance at being taken seriously by the banks that will give us a mortgage. we are going to go 50/50 on the down payment and all expenses/maintenance. we will be getting an fha loan and putting 3.5% down which will allow us to have a big emergency fund.

HUD also has emergency one-time programs to help folks keep their housing.  

One of his rental homes flooded, and she threatened to sue him if he set foot on the property.I just assumed that standard landlord law gave him the right to enter a property to do emergency repairs or damage mitigation, but this lady is really freaking out and says she has a friend who is a lawyer who swears up and down he cannot enter the property without her permission.Any words of wisdom?

Emerging market with positive future.
