I’d enjoy speaking with someone who’s done a land development project successfully and how they “vetted” the deal. 

I am 46 and have a short timeline to get to success.

So I had jumped out with out the full scope of knowledge of what I needed to do to be successful.

House-hacking is a great intro, starting young is a huge x-factor so you're in a great position, I started at 23 & I really credit much of my financial success in life to making that first leap of faith.

Each of us bring different things to the table but we don’t know the best way to setup the business for success. 

I tend to agree with this statement and have been successful in helping companies identify their profit producing activities and then create systems and processes to make those easier. 

I take no pleasure in being blunt, but the first warning sign was a 17% interest rate--sounds great to an inexperienced investor, but the realities of the real world make that VERY difficult to be successfully paid. 

SonThere will always be just enough folks who claim, or perhaps, even demonstrate, success arising from the "coaching" or "courseware" offered by the self-proclaimed guru to provide some air of legitimacy.  

I'd rather not ask my agent to continuously make offers with a 1 in 20 success ratio (or lower). 

Other than that, in general terms, you need to learn 3 things:1 - How to analyze Markets...not properties2 - How money works3 - How to develop, and stick to, a REI Business planAll three are critical to your success, and all three are equally important, and in fact, depend on eachother.
