I would find other avenues to start getting your feet wet in the industry and make sure you enjoy these strategies.

The houses are warranted and easy to rent, no repairs will be needed in a while, sometimes the builder credits are good, plus they enjoy the appreciation that you receive from buying early in a community.

By saving cash, you’ll have more money for rehab.either way, enjoy the journey! 

Do you expect to live long past that time frame and be healthy enough to fully enjoy that great cash flow and deal with the landlord stresses?

Chucaralao  the only pre-screening I ask is number of people, number and type of animals, number of vehicles, and do you smoke? 

I’m new to this and know very little but I enjoy reading and researching.

These tenants are on a joint several lease, and it's not obvious whether joint tenants can violate each other's legal right to quiet enjoyment given the unified nature of their rights and responsibilities. 

If you can house hack, like @Nicholas L. said, that is ideal because you will need the least amount down to do it and can get the enjoyment and landlord experience out of it.

There's no "prongs" lol.More than likely smoke alarms will have to be hardwired on a dedicated circuit with an interlocking wire.When the panel is upgraded a main building ground will be required under article 250 of NEC.

Should I get the police report and send a letter to the upstairs tenant reconfirming with them the stipulation in our lease of quiet enjoyment?
