While I've never invested personally in Detroit, my usual word of caution to investors in these "lower cost" markets is that while cashflow is great on a % basis, make sure to look at the actual quantity of cashflow. 

Personally, I would keep the property but I don't know your situation and if you could better use the money elsewhere.

Data point: we have a long-term rental in a popular STR neighborhood listed through Zillow right now.Every person who writes asking to do some sort of arbitrage is blocked by the Zillow platform.I don't even have to say "no thank you anymore."  

It was a personal referral, received a credit at closing for renovations as well How did you finance this deal?

A one-person show isn’t gonna cut it.

Unless you have a very large sphere to start it will be really tough to get going on your own.

I would say get to no many neighborhoods.Also not much in 200K range any more.$300K is the new $200K. 

Personally we recently sold one of our properties with the sole purpose of paying off a loan of ours.

For the areas of interest (you are local so I'll say suburbs west of City Line Avenue) there are few and far between -and- have many investors sitting on large sums of cash to jump on anything that comes up (where I would be navigating a reverse 1031.) 

I personally believe his contract job contract got cancelled as i know others from his company left that same week.
