I couldn’t figure out who had to even sign the loan docs let alone the personal guarantees. 

That's a good idea too, or a personal guarantee potentially if they signing as an LLC. 

If you put the DSCR loan under your LLC, it will still affect your debt to income ratio BECAUSE you'll sign a personal guarantee. 

You can just do a DBA (doing business as) in order to be a "business", since you're still going to have to personally guarantee these home loans.

It's time, money and stress for everyone involved.Can you visit the jobsite one time and have a face-to-face meeting where you pay him $1000 and sign a note that guarantees he will recieve the final $1000 after completion?

One buyer could take up a lot of your time and energy and there is no guarantee they'll stick with the deal.

It can be easier than cold outreach, especially if you offer them guaranteed rent and hassle-free management.Also, marketing can really help you stand out—whether it’s through listing on multiple platforms, building a solid website, or using social media for direct bookings.

40k sounds like a lot of money for mentorship, if you pay for something like this, definitely get a contract and even demand for a guarantee 

Section 8 comes with guaranteed rent payments straight from the government, which is a huge perk.

I'm sure there are people you can hire, but like home inspectors I'm sure none of them will give you any type of guarantee.
