She needs to immediately ask a lawyer about getting a temporary restraining order in place that forces the abusive spouse to leave for the safety of the children & her.  

But I'm not sure this model is sustainable or viable over the next 10-15 years as Amazon and Google start to grab more market share of retail purchases away from store front businesses.

YUP there are all sorts of reasons someone would not want a property on MLS.. but safety  and the risk of theft etc are a few. 

@Michael Baum I use RemoteLock - looks like they've phased out the model I have, the equivalent is the OpenEdge RG deadbolt.  

Build some reserves for safety along with that 10k ... then start 

You’ll learn new skills and you’ll learn you can thrive without the salary safety net.

It's better to have more then that for a safety net but he was fine and after short rehab got a tenant in there on a 2 year lease.

It doesn't matter if you are having a bad day, the contractor is on their last straw on how many days in a row they need to work, or whatever other excuse you can pull out - unless it's an emergency where safety is on the line, don't act like a jerk toward someone who is trying to help you out.
