I cannot speak directly to the Houston market as I am primarily focused in NH and MA, but I figured I'd share some insights and thoughts I have based on what you've said.First, you do not have to be handy to successfully complete a fix-and-flip, AND, you don't initially have to have any contract contacts.

Everything is part of the deal, whether its find a contract, finding the property and location, location matters the most.

I have 2 and 1/2 years left on my Army contract and my goal is to be financially free through passive income by the time that contract ends.

My wife an I made a contract on another house with a contingency on selling our current house.

I have a contract on a 14 unit.  

I've identified and am under contract with something that fits my profile.

I've got my first property under contract and had it inspected a few days ago. i've looked over the inspection report and the major issues i see are related to foundation problems.

That being said,  I do believe that you can get all of those connections (and maybe find even better ones) once you really get up and running, and as stated by BP in some of their podcasts, you don't need to use contracts from an agent. 

But, things change and life surprises us.Ask the seller if they will do Seller Financing or a Land Contract or a Wrap (and have a title report and have an attorney put the paperwork together for you.)

You need to build a team on the ground who can go to your appointments and sign contracts.
