It seems to me that until you own the property the sons have no real motivation to move. 

Today, I spoke with a lady about her single family property that she is motivated to sell.

You can't go wrong, now i would chase the deal, look at both areas and find motivated multifamily property 

An employee would be looking to grow with the business and have motivations for a small business to do well so they can do better unlike a contract employee.

Find your motivation.

I sent him the comp search and he hasn’t responded since.I’m now worried about this realtors motives and he clearly doesn’t have my best interests in mind.

That book got me motivated to think differently.

She’s really motivated to sell. 

I'm determined to find that motivated seller that makes the numbers work!

And if a buyer gets "cold feet" as was said, they need to use that as motivation and then find a valid reason to get out of the agreement, but "cold feet" as far as I understand the law as a layman, is not going to be sufficient.
