If the rental is more than a day trip to visit schedule some time to inspect the rental in the first 1,3,6 months.

POOR CHOICE- Airfare & hotel charges for 1 person, assuming trip.

I am looking to invest in C+/B- areas for cash flow in Detroit.Last market which did not work out was Denver-everything is extremely expensive with little to no cash flow and minimal opportunity to value add and even with that little to no return.I picked Detroit cause I lived there for several years and still have family in Metro Detroit so make a trip there every year.Any thoughts on TurnKey companies that find wholesale deals, potentially help with rehab and also have PM's to manage?

There's nothing wrong with that and It's often impossible to jump from the lower tier properties to more expensive real estate after the first round trip because most fail to make a profit.

I have not done a deal with him, but I have met him numerous times and feel he is a man of good character.

In answer to your original question, you'll need to run specifics on your total taxable gain and the character of the gain, 1250 recapture or capital gains.

I just went on a 43 day cross country trip with my family.Happy to connect.  

Are these right of ways free and clear of any tripping hazards i.e uneven sidewalk?. 

I've heard tales from landlords whose inspections failed due to a pulled thread in a carpet now being a "trip hazard".No thanks. 

Since you are in Long Island and considering these areas, the best thing to do is to take a trip up there and decide for yourself.Take an area like Philadelphia.
