Last Dec was no different, i send in the money for the license, fill out info and expect a reply shortly thereafter.

Would anyone be able to find me a very hard lead's contact info?

Ideally, one unit I can rent out long term and one unit for short term (3-6 months seasonally) that I might use every once in a while / on the off season.

Don't take short cuts.

I get MTR leads from Airbnb and do bookings through the airbnb platform.I use apartments.com to manage my Long term tenants and collect rent.What do I need to keep in mind for starting off on the right foot for book keeping?

What is a good area to invest in or around Detroit that would yield  good cash on cash returns( long term, midterm, short term rentals).

Everyone knows someone and you would be surprised how quickly you can start getting leads.

The entire premise of this post leads to challenges. 

The remaining 85% is subject to bonus depreciation for the part you use as a short-term rental.

A buyer will be stuck with tenants for a short while, mostly likely earning less than expected returns until rents can be stabilized at the projected numbers.
