@Sean Pincus   Sean wish it was that good out here in Portlandia  24% is rare.. 10 to 15% is customary I just hit a 20%  and I have bouncing off the roof with Joy !! 

The numbers are as follows:Sales price: $115,000Insurance: $452/yearTaxes: $1252/yearUtilities (gas, electric, water, sewer, trash) (Unfortunately two of the units share a meter, so these are paid by the landlord for simplicity sake): $300/monthRents: $1645/monthThe roof has been replaced within the last year.  

., foundation, roof, mold) to cosmetic. 

To date... we've gotten approvals for two huge projects... roofing AND all windows and doors replaced.

However I have spent almost half of my waking hours fixing roofs, furnaces, sump pumps, and painting. 

One time I was rehabbing a house (as a rental) and the elderly neighbor came over and asked if we would fix a leak in her roof.

I had to have the carpet replaced, get the trash out and much more ...It's surprised that there were no leaks on the first day when the water was turned on.

Unit upstairs has water leaking into my bathroom ceiling.2.

Biggest things I would look at is whether the roof is in good shape and whether the floor seems solid and mostly level. 

And/or what subcontractors are used sparingly that could be hired on a case by case basis (roof/HVAC, etc.)?
