What kind of real estate would he buy?

Any general advice is much appreciated.50k is more than enough money, the biggest question at 22 is are you ready to buy a property and be kind of locked in for 3-5 years.

.- Since we're not really in full control of the property, the Hold Harmless also indemnifies us against anything that goes missing at the property and squatters.We get asked/told to do all kinds of crazy stuff by owners, who either don't care what happens to us or haven't really thought everything through.Hope this addresses your question.

I can probably teach it, but I won't be spending that kind of money for the platform and I doubt people who wants to learn are willing to pay for the platform and tutoring fees. 

If managing it yourself feels unsustainable in the long run, hiring a good property manager could give you more peace of mind.Since a 1031 exchange or like-kind replacement doesn’t seem to be a good fit for your current situation, you could consider a HELOC if you need to tap into the equity for other investments without selling the property, although rates are high so this would eat up your cash flow.

Also in my experience it was a waste of time to send letters or any kind of marketing.

I would also look at like kind properties that are listed and active in that area too.

Or do you have to offer your investors some kind of discount?  

I would get back to local real estate investor meetups so you can connect with locals to the area and kind of get back in the game slowly that way.

Google it on the BBB to read for yourself.Did you not get any leads or did you not get the kind of leads you was anticipating?
