If a HELOC isn’t an option, alternatives like a home equity loan, business line of credit, or a DSCR loan could work depending on your situation.

What broker would sponsor me considering I'm not intending to become a full time Realtor and give them regular business?

The increased cash flow and the ability to pay down the loan more quickly are the biggest draws for me.Am I underestimating the time commitment of managing a multifamily property?

A formal business built on this seems overkill as you’re essentially paying someone for a service that already has standard model.If you and the parnter have distinct business tasks/abilities (i.e. not what you would hire an agent or contractor for), such as off-market lead generation, that’s a different discussion.

I have a small contractor business here in Abilene that is pretty new, owned and operated by me if any of you guys need a hand.

The webpage has them based in Maryland but they aren't listed in the state's business directory.

These people do not have the time renovate property, launch STR and run the business.

I inherited a partnership in a 22 unit commercial building with 8 restaurants, a grocery store, a couple of personal care services, and various other businesses.

If you do a good job and make the private lender happy they will want to do this again.Then there's seller financing which you see a lot with businesses, and commercial property.

Use this partnership as I way to learn how to crawl in the house flipping business.
