Just pay the lowest number that the seller will accept.If they think $500k is fair and your numbers work at $500k, then pay $500k.If they think $350k is fair and for you it's a home run if you paid $350k, then pay $350k.You're running a business not a charity. 

I'm either running a charity or a business.

@Nikki Taylor are you trying to run a profitable business or a charity?

I am sure it is not easy for the op to have to evict someone in this condition but this is a business, not a charity. 

But, he said that single member LLCs do not offer great protection and so to make it multimember I can have an irrevocable trust own 1% with a charity as the beneficiary since I don't want relatives to be involved. 

@Jay Hinrichs your new logo looks like a potential prototype for Hillary in 2020NOpe just raising money as a charity to put a first responder into a home free and clear.. and hoping all these successful real estate folks on BP will join in on the mission.. that's my BP mission going forward..

Consider a CRT - all gains on sale are tax free and can take withdraws until death which then gets donated to a charity of her choice.

We’re not running a charity.

I don't want this to be a charity case , so I'm trying to figure out a way to "purchase" or "finance" the house without actually going through the traditional home buying process. 

In lieu of flowers, please consider a donation to Metropolitan Ministries or a charity of your choice.
