We replaced the old roof as part of the project and had the interior walls primed (with Kilz) and painted. 

It appraised at $553k and the inspection showed lots of minor to moderate deferred maintenance, mainly needing a roof and some foundation repairs and a few water leaks inside that need addressed.

Do that an at some point you will end up buying a vacant lot that used to have a gas station on it, that still has the old buried leaking tanks and the oil change guys just dumped all their oil changes behind the shop, and you will now be responsible for EPA cleanup to the tune of 100Ks. 

There’s no indication that the leak is coming from the roof so it’s got to be from the walls or the ground but I’m at a loss on how to diagnose the cause and fix the problem.

It would likely depend on state regulations that may dictate whether an owner/operator could live under the same roof as residents ( a casita or guest house may solve that issue).

The house needs a roof and potentially a new septic system installed which they also considered. 

This morning she said the kitchen faucet is leaking at the base. 

For future years, we probably wouldn't meet the 500 hours test (though we still do participate a significant amount as we periodically re-stock supplies at the place, handle most maintenance issues due to shortage of workers in the town, and monitor sensors during guest stays - leak sensors/heat/stove).Specific Questions on Depreciation:Assuming that I have the qualifications for non-passive activity, I then have some questions on bonus depreciation and related stuff.5) It is my understanding that Qualified Improvement Property (QIP) bonus depreciation is probably not useful for me because I did most of the renovations prior to placing the property in-service (save for a few things).

I called the agent and it sounds as if the issue was really with the front porch allowing water under it and causing water to leak into the basement.
