my advice for anyone who does not live in the area is to concentrate on North  Jackson and the east side of hwy 55.. these will garner the better tenants and will perform better for an out of state investor.. little more money but much safer.you get into the wrong street in south Jackson and you are out of country.. it can be pretty tough I wrote an e book on what to look out for when your out of country.if you go to turnkey reivews website you can down load it for free..

I am working on an ebook on the subject.

There free ebooks, guides, blogs and Podcasts and more to help you get started.

Sounds like a complimentary business model, many of the dedicated Pizza patrons trending toward corpulence ultimately becoming diabetics and thus may need dialysis. 

They have e-books as well and possibly audiobooks (I believe on Audible).
