I would like to start connecting with lenders, attorneys, realtors, title companies, and all other professional in the SATX commercial real estate market.  

Many companies out there that can facilitate this.

Connecting with an insurance company may be helpful in placing long term tenants in a fully furnished home.  

@Jason Dillard Even if the EDM is refundable, point me to the title company/brokerage who serves as escrow agent and returns EDM's without mutual sign off from both parties to the sale contract.

I invest, flip, and own a property management company in CT. 

When I worked with a property management company, we had someone buy a unit (single family) that had a STR and marketed it as a STR.

In my case, I have residential rentals in one LLC, commercial properties in another, self-storage in a third, and my real estate company operates in a fourth.

Do you hire a title company for all the properties you're interested in before the auction?

As a management company, we also have a duty to get a property occupied with a qualified resident as soon as possible and sometimes that means adjusting rents down for right now to generate revenue.  

No I would not go with a company charging that.
