The data was broken down into 3 tiers: high-, mid- and low-ends.

Since the house is a foreclosure there are a lot of issues such as:Downstairs(basement)If anything is missing or broken on the walls its going to need sheet rockTile on the floorsFurnace / hot water needs to be re-pipedMain floorWhole interior of the house needs to be repaintedTile on kitchen floorNew appliances / cabinetsLaminate floorGranite counter topRecess lighting1/4 inch sheet rock on the top of the kitchenBathroom re-tiledStairs re stained UpstairsNew door for bedroomsNew light fixturesSame laminate floor downstairs used upstairsCompletely new bathroomOutsideRoof needs to be fixed (not replaced)Foundation needs to be paintedFront porch needs to be touched upSo basically that is what needs to be done for the house.

Are you going to add value by doing upgrades? 

Also, how can I try to raise the rent amount,upgrade something?

@Ethan Sonnichsen My preference is to have very nice upgraded units with central AC and we have even stated putting granite in for counter tops.

.- Paint is peeling of the walls and a lot of plaster is broken.

So I drive the car for personal needs for a while and fix what is broken.  

They haven't actually moved out yet so the lease hasn't been broken. 

I'd like to see an example report... might be enough to convince me to upgrade :)

So, you'll be doing a full electric upgrade.
