When you generate the map, all items with the same group value will have the same pin color.

Eric,Without going into too much detail on each line item, at first I use my back of the napkin method with a 40-50% expense ratio.

What were the biggest line items?

My PM includes any invoices for repairs in the monthly statement as a line item.

I focus on mid-grade quality items that are durable and pleasant to use yet not so nice that people are tempted to swipe them and are then expensive to replace.

Look for a place where you can secure items that you do not want tenants to have access to. 

Sorry one additional item I hit post too soon...The reason I asked about TIA is because you generally want to get a contractors opinion of cost prior to lease during that negotiating phase so you know how much that TIA covers and what you'll be coming out of pocket for.  

However a couple larger items that should have been discussed: the pipes would freeze every winter (we've since found a fix), no water shutoff exists in each unit, the well pump has to be turned off and cut water to all 18 units, no pest control was ever done on the property, there was a unit that would take on exceptional water during rain due to improper prep and installation of a new concrete slab.

Cheap items will break sooner and require replacement, and will make your place look cheap overall. 

.: I didn’t realize the closing statement items were handled a different way and not included on the SchE.
