The tenant said that the dog is well trained, 4 year old mixed lab and doesn't bark.  

If your apartment building has criminal activity such as a meth lab, the city will close your building down.

Some IT people build extra computers to mine bitcoin and other cryptocurrencies, or set up small labs (consisting of a few computers, servers, and some networking equipment that would normally be found in a business) to practice for IT certification exams.I agree that shared utilities with one tenant paying is a recipe for disaster.

Your property could easily end up being a meth lab or a crack house.

The doctor's report and a lab test confirmed being exposed to the mold.

I got a question for everybody, what jobs do you guys currently have or if you are a full time investor what did you do before that, I am still a lab assistant, I make $10.60 an hour but I gave notice and my last day of work is the 17th of august then im a full fledged investor, I just wanted to know what everybody does for a living.

Maybe she doesn't want you to see her meth lab!

A lot of the "vacant" homes in the real Bay Area are drug labs with straw owners. 

@John Vietmeyer We have them in our primary residence. (1 GSP and 2 labs) They are durable and resistant to scratches, we also picked the ones with a greywash to help hide any scratches from the dogs.I don't recall if ours is 6.3mm thick, but the original padding that was underneath made the flooring sound hollow, so we replaced it with a thicker pad and it solved the issue. 

Integrated that with a very early google Labs map system.
