inundated with real estate courses

[-TW]

I've already started doing research -- getting names + addresses of people who did owner financing maybe 1+ years ago. The idea is to offer them a cash-out deal, then sell that deal for somewhat more than I got it for -- and I end up with the difference. An arbitrage finder's fee, kinda.. The so-called 'cash flow' biz. Any experience with that?

Thanks.
