Definitely use an attorney for these ahead of time to flush out all the details.Keep up the grind!

I cutoff the master water and the leak has stopped.I'm using a shop vac to get water off the floor, flushing down the toilet.I plan to call After Disaster / some such Tomorrow.

I screw this on the inside of the stringer, flush with the bottom of the tread. 

Pour down all the drains and fill toilets and drain back of toilets by flushing it.

Who will be responsible for flushing the system to prepare for winter?

It's flush with intelligent buyer's finding it, active in-it, agent's busy with those, and NOT seeking more buyers.

Not legal or tax advice but there are a number of ways in which this could be structured depending on your investor's risk/reward desire and your risk/financial strength.The main ones being doing a LP/GP structure where you get a promote and structure the promote/carry to be treated as long term capital gains or offer your investors a private note in which case you get to write off the interest they charge you as expenses and if you are still getting a promote at the back end, that would be long term capital gains.Don't forget to flush out how the depreciation and any depreciation recapture upon the sale would be treated.The amount you are seeking to raise is not high and if you already have existing investors, ask them what their preference is and structure the docs accordingly.

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.
