Luckily, we charged a double deposit because she had no credit as in 0.

Hi Beau,I am not sure what the prices are in Austin but in Dallas Ft Worth my installer charges $40 per sqft. 

How accurate is the is  ACHA Fair Market Rent Schedule vs. what you are receiving/charging?

Can someone still obtain a realtor's license in Texas  with having a  misdemeanor domestic assault charge on the record and the offense  occurred  almost 15 years ago ?

I charge them a nice large fee when they forget the rent and I send them free mail when they really forget the rent.

Lender-paid PMI (or LPMI) is a thing, and PMI doesn't have to paid monthly.So I would get a Loan Estimate from the lender, ask about points and origination charges, find out of PMI is being paid in lump sum, and that might be the key to why it seems like such a good deal on the surface.

Imagine buying a 1M property with all cash and charging 3K per month in rent. 

Check your local laws, but in many cases if you (owner) is the one doing the cleaning, you can't charge for your time. 

We purchase and rehab everything and fix it to the 9's to avoid unexpected capital expenditures.

The only way to really know is to just run every single property through these things to see what they're going to charge you.
