It sounds like the trailer park made a few GRAND lolL!!!!

You put a 2/2 under contract for just under $600k and it's a grand slam of a deal worth bragging about?

Units are front hold high efficiency speed queens worth about 2 grand a piece, dryers are propane.  

Grand kids come to visit.  

Kids should be long gone by this age but an extra  (2nd) bedroom for grand kid or freind visits would be good.

What kind of legitimate lawyer would want to spend hour(s) defending a claim for a couple grand overdue rent in what amounts to basically a notch below traffic court ...?

Regulations change for STRs and the market can become saturated.Personally, I like Ann Arbor, Lansing and Grand Rapids, Michigan for STRs and LTRs.You have to know the local restrictions and regulations on STRs in those locations but you are much more likely to be able to buy a property that will cashflow as a long term rental and cashflow much better as a short term rental even using property managers.To your success!

It was mainly bought as a house for my grandparents to come visit grand babies and turned into an STR: its a tight margin market right now even for STRS.  

My research shows the counties of Ottawa, Livingston and Grand Traverse.

Not a problem to wait 6 months in the grand scheme of things (unless it was purchased with tight deadline/balloon debt), but it's unexpected.
