The house sits near a freeway junction and a busy street, and while my previous rental was also close to the freeway, something about this home's elevation makes the noise unbearablyintrusive.

Incredibly poor business deal. 

I would check with your CPA before setting anything up.If you are talking about referring people to local fun businesses like the boat rental, restaurants, amusement parks etc then there is no problem.

Looking for some guidance on resources of how to begin analysis or how to build a business of this sort.

Or start a business which would require a lot more time than owning RE.If it were me and Dallas is appreciating, I'd probably hold onto it since you've had it since 2011.

I finished my business plan finally recently.

Edit: For SFH A simple answer: everything is negotiable and every agent runs their business differently.

So I ended up using 0% interest business credit cards which I liquidated to purchase and renovate my property (total credit limit of about $95k total).

These are leased to businesses (like chain stores) that cover taxes, insurance, and maintenance, making them much more hands-off than residential rentals.Real Estate Syndications / REITs – You can invest passively in commercial real estate (apartment complexes, self-storage, industrial, etc.) through syndications or real estate investment trusts (REITs) without being a landlord.Hard Money Lending / Private Lending – With $500K in equity, you could act as a private lender, funding real estate investors who flip homes or develop properties.

You'll learn a lot here.I recommend focusing on 1 strategy/business model and going all in on that one until you've mastered it and it's stable.
