I previously relied on 3rd party GC's building quite a few single family to 4 unit buildings throughout Philadelphia and eventually transitioned to self performing.

I get NO notification from system that tenant has not made his final payment, since payment series is archived on DUE DATE of last payment.

No one will probably tell you they wasted their money on something like this.   

If more people used their heads, and less people kept on regurgitating absolute nonsense, this ENTIRE space of REI would be far more successful.

Here in San Antonio we are perfecting systems for doing un-accompanied (no agent present), vacant home showings.  

Ive been emailing BiggerPockets for over 2 weeks with no response which is a little disheartening.

Specifically ERVs. I'm working towards Energy Star in my new 4 unit build because it's fairly easy to get slightly above code and cheap to have the raters come and certify you with the Energy Star label which would ad...

"no, I don't live here sir, I just come here to work and think most afternoons, then I go and couch surf at a friends house".

This can have a very beneficial impact as personal property typically has a much shorter useful life for depreciation purposes than real property.For example, if you are getting a cost segregation study performed on a commercial office building, there will most likely be assets that have been classified as part of the building but are able to be reclassified to real property and depreciation over a shorter useful life such as 5,7 or 15 years rather than 39 years.

I still have no deals under my belt but I did get experience seeing first hand the "ins and outs" of deal structures working under an active investor.
