I'm not going to make an emotional decision because it's my mom.

I would hope we go into business with people we trust, but still we usually outline how things should go in the event of things going south as it is easier to compromise fairly when everyone is levelheaded, rather than after the fact when emotions are on the line.

Go talk to a landlord of a rent controlled or stabilized apartment in New York City.  

Have control over things that are your responsibility.  

Scenario: The sellers are backing out of the deal, but you have considerable amount of time, sometimes money, and investment emotion in a deal and all of a sudden... seller changes their mind?

I make money when deals close - not on all the BS before there is an offer, so I control my activities that could be a waste of time.

It was my former home that I turned into a rental, rather than selling, and I brought in a property manager to keep from being "emotionally attached" to the decision making.  

All real estate agents log into a subdomain of MLSListings (pro.mlslistings.com) to enter and access listing information.The Silicon Valley Association of Realtors (SILVAR), Santa Clara County Association of Realtors (SCCAOR), and the San Mateo Association of Realtors (SAMCAR) control who has access to enter listing information into the multiple listing service and by setting standards of conduct, regulate real estate agents.

Stay in control of everything you are responsible for.  

I would steer clear unless you are able to purchase both sides so you have complete control of the property.
