@David LiuNot sure about your market, but septic inspections here normally will snake the tank and leach field with a fiber optic line / camera. 

Mine can set door codes, message (or call) guests, schedule cleaners, adjust the thermostat, monitor my cameras, & call a plumber just as easily as a local PM can, for 1% of the costI wrote much more about leveraging offshore assistants in this post here.

I have installed the fake cameras and plenty of signage but that doesn’t seem to deter whoever is throwing it.  

Hiring that tenant/friend would be far less costly and quicker than hiring a lawyer and should you end up in court your original tenant would testify he sublet the place...he owes you after all.If you do not have the grit to go that route then your first step, along with lawyer, is to enter the unit (with proper legal notice) with a friend(s) and a good camera.

This man spits out gold but you need to go through his posts to dig it up.

Do you put security cameras up? 

I know there's the liklihood of interest rates going up, but they aren't going to jump uo to double digits this year. 

Plus when you're paying double digit interest I highly doubt these properties will pencil out.Lastly, you realize that cash out refi will only allow you to pull out up to 75-80% of purchase price or appraisal value.

Time to trim the fat and find ways to innovate.I’m interested in digital door locks that are on the market (like these).
