Buy anSTR with double digit returns?  

Get smart doorbells with a cameras to see how many people enter.

I can't find what I want at the brick and mortar bookstores because I am reading advanced topics.Amazon had print format and kindle digital but not .pdf I am used to ordering a digital book online and saving and reading in .pdf.Does the Kindle digital reader app for Desk Top hog resources and constantly run in the background??

Marc, some parts of the Texas market are the hottest anywhere in the nation, especially Austin with double digit appreciation rates expected for the next 3 years.

The best bet, if you have the ability, is to go through the place with the landlord and a video camera, and record every square inch of the apartment.

you need to check with the city if that porch had a permit pulledYou have no idea about the plumbing situation or electricity (you spot rat droppings ..you wires might be gone)…are the pipes sloping correctly, do they drain, non-visible leaks does not mean that you are ok, maybe it is a good idea to either perform a compression test (if part of the plumbing is missing and you really want to save those old galvanized pipes) or snake a camera into the drain to look for the roots on the way.

Although as Tyler mentioned, the cap rate is 5%, not great.For those that are willing to put in a bit of effort, recent zoning changes make it possible to get *really* good, one might say, downright un-Canadian, double-digit returns. 

LOLMind you, I automated everything: Keyless Entry with Z-Wave system, Thermostat, Cameras, etc.

Run a camera down the sewer line to check the sewer line to the street.

It's a lot of research (understanding the area, what renters want, what the prices are daily)  a lot of online marketing skills (I own a digital production company that works with influencers to expand their social media presence) and buying the "right"  place and branding it correctly.
