I'm wondering if I'm missing anything: Mortgage (20% down, so no PMI) HOA Electricity Gas (None, as the new construction house has an electric stove—everything is electric) Water Bill Camera Security System Internet Lawn Care Regular MaintenanceQuestions: Will I need to pay for trash? 

It's better than what you'll get from most attorneys and what you'll find on the internet.

STR is becoming a difficult strategy because there are so many costs (furniture maintenance, utilities, internet, etc.) that you have to factor in and if you are in an oversaturated market, then unless your property is unique, you can only compete on price.

As mentioned, Killeen-Temple has a much higher concentration of duplexes and fourplexes.

I got into detail of what they were looking for first.. then I qualified that they had the money and were ready to go ( like a good car salesmen does) then I picked 3 properties ( back before the internet ) One I knew they might like one that pretty sure they would not and one I knew fit all the criteria and they would buy. then I asked for the order point blank and wrote it up usually on the Hood of my car.. contract with NCR paper and off er went to escrow. 

Hows it the biggest change to the industry in a century...when literally 25 years ago the MLS was not on the internet, and thus commissions not easily discernible from going to an online MLS.Literally we are just going back to something that existed in the industry not that long ago.

I am a real estate investor (with a concentration in buy-and-hold properties) as well as a Police Officer for the city and I will warn you that crime is an issue.

A few things I haven't liked about lending include the concentration of risk and the high tax rate.
