I'd love to ultimately be able to do the BRRRR method, but my biggest hurdle will be getting loans without being a W-2 employee. 

I've put in a few offers but, no luck yet though.The Houston MLS is a great source of deals, at the moment. 

I wouldn't trust a form you find online and partnerships like that are the biggest cause of nasty litigation in the business.

Cashflow is going to impossible if you are unwilling to put in hours to source a deals and put up a lot of sweat equity.For me my sweat was better off put at my day job and buy out of state rentals that cashflowed.

I'd like to know what were some of the biggest challenges you had to over come, starting out in your REI career?

List Source?

I have a Purchase and Sale Agreement I use all the time (sourced from a closing agent many of us use in GA). 

Has anyone purchased a pre foreclosure list from list source, and marketed to it ?

@Jeff MillsBe careful of your property source.

I've been trying to avoid continuing to post on this thread because you have been given the correct answer multiple times by various credible sources, but continue to argue your point, and it is tiresome.
