If the current tenant has rented that unit for awhile, they might have an emotional attachment to it so me pulling one behind their back wouldn't be fair to them nor would it make my reputation good in the area. 

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 ?

Coffee is going to over personalize a situation where a person is MOST likely to use personal emotions against you.Late rent needs to be dealt with firm, fair, and expediently.

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. 

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.
