Hi Paul, I'm from a different area than you, but the situation you are trying to prevent is common to all landlords and property managers. 

When I do flips I always know what is necessary and if in doubt I know it isn't.Every unnecessary dollar you spend comes straight out of your profits.

Could have interviewed more than one realtor and got 3% rate but as a buyer you will not be paying that unless the seller isn't willing to pay 3.5%...Also charging you for the monthly rent is so unnecessary!

Three evictions in 17 years, rent collection is automatic via ACH, maintenance is always preventive so late night or emergency calls from tenants, etc.I have recently changed to having only one group showing a few weeks after the current tenant gives notice that they are moving out.

Seems like an unnecessary racket.

What is preventing you from buying more?

For example, differing state restrictions would not prevent someone living in a state other than where your parents live to pursue a strategy like this?

That is totally unnecessary. 

Does anyone know if this will prevent me from getting financing?

We also have a very fractured government with multiple unnecessary layers that can slow and impede development.
