The worst market are the ones that have properties you do not want to hold long term.We see questions like yours all the time.  

Which in theory means the buyer pays both sides at the worst metric to them. 

One of the reasons i chose ReSimpli was because I called one of the other companies I had narrowed my CRM down to (will withhold the name of the company) and they had one of the worst support teams I have ever experienced.

Id say think multifamily (mark kenny) is one of the worst, had no financial reporting and lost all investor money.

Best/worst markets?

If it's a transactional relationship, then worst case scenario, you don't work with that person again in the future.

The worst part is No One answer thru emails and phone doesn't work for me (the auto system said my information is incorrect). 

Where's your worst case scenario? 

After 6 years that is still the worst trashing of a place I have ever experienced.The next time this happened, 22 people showed up to a cabin with a max occupancy of 8.  

Usually, their worst-case scenario is the loan gets paid back.
