Your property will have less vacancy if it's in a good school district compared to a property a couple of blocks away in a poor school district.

@Tue Huynh-Nhut Vo The base price I assume of about 150K x house already reflect the premium for Student Housing...2 blocks east and west of the student area prices drop to 80-100K for similarly sized houses and rent drop more then half.Thanks again...and appreciate any new insights...

If so, you'll definitely want to drive the neighborhoods and blocks to get a feel of what is really going on.

I have 2 rentals within a couple of blocks from one another and in the same sub-division. 

Turns out this fellow also has 3 other properties that he wants to let go of in the same neighborhood(2 on the same block); 2 duplexes(neighboring lots) and a triplex around the corner.  

Even if I had a rental down my block, I would prefer to have someone else handle the midnight plumbing calls.

You can't go 3 blocks without seeing half a dozen "for rent" signs.Thank you for your tips on finding houses that will cash flow positive, and I completely agree with you.

@Alex VelazquezDetroit is very block by block.
