You pretty much validated my concerns with purchasing or rehabbing within certain Class standards. 

What concerns me most is that statement: "I have yet to have a conversation with a seller"Here's the truth: It'll probably take talking to 50-100 prospective sellers before you even have a shot at getting a deal.You don't get to change that.You do get to decide how long you'll take to get those conversations completed.Reach just 1-2 sellers per week and it'll take you a year or two before you get a deal.Reach 10 sellers per weekday, and you'll likely get a deal within a month!

If you are younger and seeking to rapidly build a cash flowing portfolio, if you are wanting to continue 1031'ing into bigger assets, or if you do not have the cash to take down entire deals without financing, leverage makes a LOT of sense.If you are retired (or rapidly approaching retirement with a level of uncertainty or concern about what your post-retirement income will look like), it could make sense to begin paying off properties so that you reach a point where your expected monthly cash flow will exceed what you need to live comfortably after retiring.
