@Clay Walker yes you can rent out rooms in a primary SFH provided you are also living there.

Central PA, i heard has over 190 new realtors entering every single quarter... (3 months )

Cash distributions from my experience have come quarterly which is a nice boost in those months.  

When you get back 9 time in 10 the response is no.Inspect your properties regularly (quarterly) and immediately issue letters to correct problems or hire a contractor to repair tenant caused damage.

I'd look for deals in the suburbs South of there and be aware of clay soil and foundation issues.

The gravel driveway to the property is probably between a quarter mile and half mile (really long).

I made my own spreadsheet and update it quarterly.

How can they allow a resident to bring in a new animal into tight living quarters without knowing if it barks all night disrupting everyone, whether it is aggressive, whether it listens to the owner? 

The backdrop is skyrocketing rentals in the biggest metropolitan areas: New York and Los Angeles, where a quarter of the nation’s homeless live, have seen rents increase 20% and 30%, respectively, since 2012.Is anyone seeing people priced out of their homes in Jacksonville?

Spending a quarter million dollars to only get 3 grand a month isn’t very exciting .
