My end goal is to become and active and reputable Real Estate Investor.Areas of Interest: Dallas/Arlington/Fort Worth-Wholesale/Agency (I understand there may be conflicts of interest if not handled properly)-Flip/Rehab-Buy & HoldDoes anyone have any suggestions?

While there are some shady characters out there, just like in every industry, there are a handful of very reputable ones.

Hey I'm sure you've found someone, but If not I have reputable contractor in Oklahoma that has been in the business for 20+ years in roofing & construction.

They provide a nice centralized marketplace for syndications, which could otherwise be tougher to find.Now that I know this exists, and due to the fact I’m accredited (so I can invest in all kinds of fun stuff more directly than ownership of a public equity) I am wondering if there are other reputable platforms that facilitate direct investment in other alternative asset classes.

You’re right, and I have a good reputation around my area.

In addition to choosing one with experience with 203k loans I would vet lenders and look at their local reputation.

Is it a greedy seller who wants top dollar for a pile of poo, or someone who is actually going to work with the guys/gals who are going to execute the project and have their butts/reputations/credit scores on the line?  

Justin, You can rollover your 401k into self-directed IRA, but not into HSA, which is Health Savings Account and not a retirement plan.There are several reputable providers here on BiggerPockets who are active on the forum, just search the forum for related keywords and you will find out who they are.

The team seems reputable, but it's also my first investment property and I don't want to get burned. 

I had no clue what I was doing and lied to cover that up, it ended friendships, gave me a reputation among sellers and buyers, it was hard to make anything happen.
