Of course, there could be details that weren't mentioned that could change my thoughts on this, but on the surface, it sounds like you are in a pretty stable financial position that could weather any investment property hiccups without risking financial ruin.The real reason I would consider now versus waiting though is experience. 

I have only  good credit score ranging from 774 to 784 , I have good stable job ,and My debt to income ratio is 20 % Which is mostly my  current Mortgage.

Sec 8 just assists the residents with rent, but still make sure you have clearly defined criteria that you will uphold for all of your residents- such as criminal background checks, stable job history, verify employment, must have good landlord references, no prior evictions.

I suppose a more pointed question is whether or not it is possible to attain this goal by purchasing a run-of-the-mill turnkey property at retail, every year for 10 years, in a stable market like Indy and applying all excess cash flow to principal reduction.  

Although I won't be getting started for a few months now, I am working to get a stable ground work for what will eventually (hopefully) be my RE business. 

But I had no clue when I read it.....I saw pony in there and thought maybe Will was running some sortof horse stable on the side. :-)

We have another tenant that always offers me top shelf shots from his full bar in the kitchen but I decline.

I also prefer stable income streams rather than volatility, otherwise I would have just stuck with equities.

Basically I'm targeting individuals that may not earn a LOT of money, but they have stable jobs and are looking for quality housing for their families. 

The higher the yearly cash flows, particularly on the front end, the more this number is skewed to the high side, assuming you can't match those yields.As for "high cap rate properties", these are almost always unrealistic projections on D type properties, that assume "normal" vacancy/collection rates for stable properties and a disregard for higher levels of vandalism and such.
