I purchase buildings all the time due to their being under performing assets. 

Better to overestimate and out perform than underestimate and hit a brick wall.  

Start with a manual process, then automate parts, being sure to create a way to track the performance of each marketing piece.  

Starting out you may not have the most optimal tax sheltering or liability coverage...but those can be fixed later down the road. 

But if there are particular 5 caps that are under performing I would consider trading them for better assets.  

I use excel and consolidate all income and expenses for each property (I add my mortgage payments and other landlord expenses) and make sure that my cash accounts reconcile for all my holdings (if there is a problem I call the manager and we try and figure things out).I use this excel for two things: Tracking my properties performance - mainly cash flow, cash balance, NOI and just to make sure the PM is on top of everything.I use this to input the data into QuickBooks (I do this manually). 

This is a non-performing, unsecured note.
