That being said, as @Marcus Auerbach stated above, the spread will be rather thin under the 100k mark so I suggest investigating other neighborhoods that offer more variation in home values. 

Your first few projects will be the most difficult; however, "high-level" figures on cosmetics and standard replacements (furnace, A/C, water heater, etc) don't take long to master (at least within 10-15% variation).

I always thought that Rent To Own was like a "Layaway" type of process, except that in Real Estate you move-in to the house.The article sounds more like a "Try" before "You Buy", while paying a premium during the trial period. 

There are exceptions of course including my first deal but it comes down to trial and error.
