Also the importance of screening your tenants properly.

I wanted to be preemptive and see if anyone would be willing to give advice on how experienced investors screen their tenants and what paperwork is used.

Beyond that we screen pretty heavily and don't really have a problem with theft.

A good example is Application fees- those were unheard of back in the day, now the are ubiquitous and a revenue stream for many. many tenant groups are fighting against application/screening fees and IMO these will be legislated against this coming year. 

Break any of those rules and a good attorney will "pierce the veil" and you LLC is as protective as a screen door on a submarine.

Also learned a LOT about how to screen and manage tenants and contracts.

I removed the enclosed porch screen door and installed a more substantial door (as the porch wall was one the exterior walls to the pipe).

The duties of a typical property manager include collecting rent, arranging maintenance, enforcing apartment rules, dealing with 3 am plumbing calls, conducting inspections, completing repairs, paying bills, advertising vacant units, screening tenants, etc. 

These systems are free for a certain number of units (I think 75 for TenantCloud) that allow you to market your rentals, screen applications, keep tenants and leases straight, auto email reminders, track maintenance, and more.

We have smart tv's in living room and each bedroom so they can stream with their own accounts if they like.
