I'm hoping to install a doorbell video camera as well as maybe 1 or 2 exterior cameras.

I watched the youtube video for Davidson county and gathered it's more than me notifying the neighbor next door. 

I also see that in many national guru videos about Texas. 

At $500/pop that can get expensive.I have done videos in the past showing that investing in a fund collecting interest only and leaving your principal in the fund pays significantly more over time - but with a note you could get a payoff (which if bought for discount is great).

That could be used to put down the 15% down on the new purchase using DSCR.You could also do a "subject to" contract if you want more info I would look up "Pace Morby's" info or videos on Ytube.

Take your time, take photos and videos of everything, and use the chance to connect with the seller or broker.

And thank you for the links, I will go through those videos. 

Unfortunately breaking into an unoccupied dwelling is typically the lowest degree of burglary.

They don't have payments either and when their car or motorbike needs something,  their first action is to get out their own tools and pull up a YT video.  

It sounds like your off to the right start -- but watching some videos and doing some research -- keep doing that.
