For my passive capital I chose to lean away from crowdfunding platforms in favor of building relationships with great operators and investing directly with them.

Other than that work through it as fast as you can, it will build a foundation for you to use in the Real World of real estate.

I think you are on the right track however its going to be necessary for you to have some "skin in the game" sooner rather than later - while it can be appealing and seemingly possible to build a significant real estate portfolio with all of "OPM" the reality is you are probably going to need to have some equity in these properties - 20% or so down from your own funds to keep building. 

So, in other words, do the same kind of hustle as a wholesaler, find those off market deals, build up a buyers list, and sling some houses for commission fees.

They may even work with FA's or CFP's to build the team you need for this transition of retirement assets.

We do love the building As-Is.

We also purchase the templates on Etsy, brand them to our company, and add the appropriate property details/photos, then create a public Canva link we share with guests.

You are definitely on the right track with looking to build the team so you can continue to grow. 

You can find some meetups on the Neighborhood Building Owner's Alliance website. 

Plus, you can build a network of trusted local contractors for maintenance and repairs down the line.
