Not detailed, but for example - clean filthy toilet $10, clean bathtub and tile $20, remove broken chair in LR and trash and haul to dump $75, etc. 

But the issue I'm having is find a bathtub that will last because it's going in a tile surround.

If you still have thick carpet or tiles, the reading won't be accurate no matter who does the reading.

new HVAC, electric panel, recessed lights, added bathroom, tiled bathrooms, opened up kitchen, new cabinets and appliances, granite counter tops, refinished floors.

I updated the kitchen with new tile, cabinets, countertops, appliances and did a wall cutout.

The county made me get an engineer to re-design the building's framing because someone put a heavy tile roof on the house.

So, if you wanted to get all of your cost (rehab and purchase) back from a refi, you can't offer more than $430.The property has good bones like I told you :NO Structural problemNO Foundation Problem I will be redoing all electrical , water/sewage , gas and probably the some thermal Isolation .Brand new kitchen , baths and tiles .Open the Layout to an open concept .So my GC estimated based on his visit on the property that rehab cost would be around 100k to 200k . 

It is best if the window well has a drain to the drain tile on the property.
