Finding it can be challenging if the leak is behind a wall, above a ceiling, etc.

Cut out stumpDriveway - I'd clean up the driveway- not sure if it needs only sweeping hard to tell with grass in the driveway-First appearances matter.Front porch and front porch covering- not sure what that is on top but power wash.Living room- Carpet or depending on what floors look like underneath- If wood I would leave wood depending on condition, if not wood carpet- Strip wall paper off walls and nuetral paint- Not sure about the panel.Kitchen- I'd concentrate most of my money here- Tile the floors or if nice wood in the living room then I'd just extend the wood floors into kitchen.

Maybe there are thin walls?

I could close a few walls and it would be a duplex again (plus other work to rehab).

There is a big wall heater in the living room, but since I will be putting in new window units, there is no need for it and I may remove it and seal it off.

Not to stick up for wall street but this thread is completely misleading.

I have heard that it might work.Unfourtnately everyone seems to do the pools with wood walls and vinyl liners in my area.

When looking at painted walls, can you tell if a job is good or bad?

If not, I would adjust the labour rate to be whatever Moly Maid and "1-800-Got-Junk" charged you and furnish their billing as pass through evidence with your invoice.If you did the labour yourself at a charge rate of $75/hr and do end-up in court, I would anticipate the judge disallowing it. 

I have no idea what's in the wall or what is load bearing, but if the opportunity is there, I would open up the rest of the wall where the pass through is.
