If she has already agreed to move out by the 28th, consider that a win.

Time will tell which side “wins” but so far those that indicate hospice is not residential are winning (the construction has been halted). 

If not redeemed the property is signed over to the winning bidder.A couple of details.

Definitely a win How did you finance this deal?

You can use your accounting background as leverage for a win-win relationship with a local investor for sure.

SF is winning me over at the moment because I'm a beginner, but I'm sort of stuck in analysis paralysis right now trying to decide.Thanks in advance! 

This sounds like it might be a win-win, Hospice has plenty of funding to be a reliable renter. 

Either way, I recommend finding peace with what you can't control (whether that is eviction or them living in the mobile home); otherwise, you let the siblings keep winning if they impact your happiness.

Because they are new to the business, they assume it is a commodity based business and they win business by being the cheapest option.
