So aside from some stress and need for speed, this is like any other deal. 

Reason I ask is that I've been tracking earnings based on when they are earned whereas Airbnb seems to base it off of the actual payout date.

Taking a leap and in the process of buying a home right now with a closing date of 4/1.

Have the GC tell you what time frame he can complete the project in, and then draw up your own schedule showing the milestone completion dates (demo,plumbing rough in, cover up inspection, flooring, tile, top out..etc...) 

May 1 is the whisper date around town.

I do manage my own property for now, and I do not have an electrician on speed dial but I assume a 5 minute local google maps search would reveal the best in the area to the PM.

Beware that the property owners will have a statutory right of redemption to pay their debt and regain ownership of their home that lasts for one year from the date of sale at foreclosure. 

If so, it should be fairly easy to pinpoint which costs increased and determine if the increases are reasonable.One common way for closing costs to increase is if the closing date changes.

And I mean, companies I can sign the papers with, give the money to and list on the date of the deadline agreed to with no problems.

I imagine GPs will be effected at the time of sale at a later date when determining basis etc.Thanks
