From podcasts to forums, you’ve all helped me learn, save, and build the confidence to take this step.That said, I’m reaching out to ask for advice.

Get your basic estate docs in place before building a complex entity structure.  

My wife and I are in Stillwater and have house hacked for a number of years as well as flipped and own mixed use buildings in Western Wi.

Own 10 rentals in Columbus Ohio and building another 21 new build single family houses in Florida that will be a clean BRRRR that will be free and clear.

If you'd ask this question while still employed I'd say apply the $8500 toward knocking down the debt quicker but since that is not the case I would build up your reserves to about 6 months then begin applying those funds to bring down the debt. 

Focus on saving, building your credit, and connecting with local investors.

I also have some capital to contribute.Could someone explain how syndications are typically structured, and how are people using Other People's Money (OPM) to build large portfolios with little to no money down?

This could be a huge opportunity for investors who can find cheap conversions (think: a SF with an existing in law apartment).

I am self employed but want to build a spec home using the equity in my house as collateral.

I think that a part time investor can have success with syndicated offerings and triple net leased properties if they’re willing to learn real estate fundamentals, perform “due diligence” on the deal/sponsors/property and engage legal help.
