The big problems occur either (1) a new investor with little capital attends a guru course teaching this technique and ends up washing his hands of the property after finding his particular deal to be a losing proposition, or (2) a real estate depression like 2008 where even the major players are unable to perform financially.Proponents of subject to deals will comment that the same risks are inherent in all loans and real estate deals.  

If you can get 2% from bank CD's, and your risk tolerance is such that bank CD's are what you're willing to invest in, and you want $100K a year in income, you would need $5 million.OTOH, if you have a bunch of rentals that throw off $100 a month in true cash flow (not rent-PITI phony cash flow), then it doesn't really matter how much equity you have. 

@Paul Walker $30k is tight...you can find a deal in Columbus, but you'll be confined to renovation projects or C/D locations with higher crime and lots of speculation...though, there are some exceptions to this...it will take perseverance and patients to find the right deal.Toledo will give you many more options across the board...better properties in better condition and location.I'd be curious why you landed on those 2 markets...nothing personal, but it's like comparing a Ferrari to a Ford...I'm sure there are markets in your own state much closer you can find deals in.Best of luck

So I sent the CD's and they still mowed the lawn and did another termite inspection. 

I have limited experience with the auctions, but have enjoyed watching the players bid a couple of times.

The top players (A rating with many reviews) are typically busy so if you are looking for someone to start immediately it probably won't work for you.Another thing I like about angie's list is their Big Deals.

A lot of startup types and big players tend to think they are special enough to receive a bailout.

Find the players in the area and go with them.

Hi Rex, My team and I have been working in the rental and PM market for over a decade and we've housed many baseball players (and other athletes and actors/film staff).

We like to flip in A-B neighborhoods, so I wholesale the ones that our marketing brings in C-D neighborhoods.
