I am a tech professional, but I also own a small Home Improvement company with my father who has been in the industry for 20ish years.

By purchasing something from the company, you established a business relationship with the company.

Hi BP community,I’m looking to invest in Texas and there’s a new law that the buyer must sign agreement with one realtor company or agent for the potential property. 

I've only heard this recently in a book I read, and by a closing agent from a title company.

Multiple, billion dollar companies are investing substantial amounts of money into our area, such as Intel, Google, and Amazon.

I currently work for a luxury building materials company and my commute is about an hour and a half each way every day.

How do go about making contacts at insurance companies or corporate relocation agencies?  

if you're looking at 1-4 unit properties, don't kill yourself trying to create an LLC just yet. find your lender first then see if they'll require you to close in an LLC or not. single-member LLCs do not provide as much legal protection as we would like to think, so if that's your reasoning for wanting to create one right off the bat, that's just something to consider. as far as a business license, AFTER you close on the property, call the town hall and ask if they want you to have one there bc you're collecting rent there. if you're using a PM company, they will probably say no. :)

Have you reached out to friends, local groups, businesses, schools, hospitals, etc. telling them about your rental and the special promotion you are offering to their members?

You pay a flat rate (but there are often add-ons), you create the listing/wording and take great pictures, you send it to the company, they put it on MLS.
