I actually wound up showing them the place and gave them my card.

@Ben Tilbury I am not sure, but their websites should list all their services. 

Since we purchased it, we brought power back to the property currently set up as 2 RV hookups and additional outlets on a backer board (for a total of 200-amp service), had an RV pad and driveway put in, and had the developed year-round spring well brought back online - there will be a pump house built near the backer board this Spring (1st photo).

How would I actually go about accessing the HELOC funds for the down payment?

Not being rude, but answers so far haven't addressed the actual question. 

If you find a place that will cash flow at a 200k budget on long term rents in Houston, I promise you that you do not want to own in that neighborhood AND it probably does not actually cash flow due to the class of tenant, capex, vacancy, and turnover costs.I'd suggest you try to find some connection to a place rather than randomly picking a market.

Yes I essentially have 2 services, one being property management and the other being Real Estate Broker Services.  

I bought 1% ownership, the experts handle all the work, and I anticipate a return equal to - or better than - actual properties that I manage.

You don't actually hold the deposit, from my understanding. 

He actually said a week, but I feel silly even typing that!
