Asking to anyone who has experience, knowledge or connections in these southern texas markets, how has this or does it affect your real estate strategy and returns? 

Would help if you stated what questions you had so people could reply right away.I have knowledge on HELOANs but not direct experience.

Are there any knowledgeable mortgage or finance brokers in the Houston area who have expertise in similar transactions?

And this is why I'm trying to take the necessary steps to correct this poor behavior and joining this platform to get some input/knowledge/guidance/advice.

Always happy to share my knowledge/resources.

Surround yourself with knowledgeable professionals who can support your real estate endeavors.

I have seen some of Walter’s presentations and he is very knowledgeable.

You have a skillset that could be extremely useful for quick fixes and landlord issues and from there you can bridge relationships and partnerships to enhance your knowledge of real estate investing and couple your skills.

It could be a nice opportunity however I would be certain they will want you to make up the difference between $250,000 and whatever is left on the mortgage which btw in my opinion should be done with lender's knowledge and approval. 

My personal experience after 40 + years in the real estate industry is that “wholesaling” is a very INEFFICIENT AND INEFFECTIVE way to gain knowledge and experience relative to real estate.
