You approach their kids and are accused of tampering with the old folks....I see 2 options: Either get even closer with them - in a genuine way, don't just do it out of greed (IMO) or just go straight business mode and approach them with a generous offer based on them moving when THEY feel ready to move....You stand the risk of irritating someone no matter what you do, but on the other hand, the only way to get a great deal sometimes is to walk out on that limb and jump....

If someone did contest, and accuse the buyer  of using the buyer's attorney as the vehicle of a bad faith termination, then the fact that multiple offers had been made and the buyer "really only wanted Blackacre, the other offers were backstops" then the seller of Whiteacre or Redacre could very well have a cause for breach of contract for bad faith termination.If you really have your heart set on getting Blackacre and your offer for Whiteacre is contingent on NOT getting Blackacre, then you'd better have the contingency in the offer for Whiteacre, and not  put your hopes in the idea that sellers won't challenge your attorney's termination during review.

We have taken very good care of the property which makes our tenant''s accusations heart breaking.

I'm also accused of spending too much much time with leads that don't pan out right away.

No, I don't think so.I'm not accusing you of pulling a fast one, I see how you are justifying your idea.

I don't know about DSS- but I'd definitely be careful about not accepting SSI- it's a valid income and if it meets your income standard, no reason not to accept- could get accused of discriminating against the elderly.  

Thought you were accusing me of something I hadn't even intended on doing.

I apologize for I am not making accusations here but very skeptical and looking for some real results of real investors who might take this cloud off my brain and show me the clear sky out there !!!

Your unfounded accusation otherwise turned hostile what is normally a pleasant forum space.The worst part is @Michael Xiong didn't get his question answered.  

You provide the lease, do all the screening etc. all he has to do is allow you the right to proceed and accuse to the property.
