It was on a private money lending deal where he was lending on construction. 

Look at loan options like standard loans, group loans, or private funds.

I would like to start investing soon, but my full time is brokering for Hard/Private money loans.

ADU was the biggest hype last decade and a huge disappointment for many, especially in CA. 1- big pain in the a$$ to get approved and then built. 2- super expensive in CA.3- often it reduces the value of the main home on resale, because most people want a normal private home and not some white elephant with a weird back cottage or no garage due to ADU.  

My suggestion is to use your own cash to do your first couple make sure you work out the kinks then you can leverage with private money HML or find that unicorn sub to deal.

Private lender How did you add value to the deal?

I needed all of them  RE license to sell RE  Mortgage to do private loans in the states that require it.. and contractors to build the homes I am building and then on top of that I have a developers license in Oregon ( no test required just a money grab And when I was figuring out what I wanted to do I got my pilots license around 20 too.. as I really wanted to be an airline pilot.. but alas in those days it was very hard to get hired not like today.

I was wondering if it would be better to do two private loans or one HML (first position) and a private loan (2nd position)thank you for your help!

If you're able to keep it relatively private, I'd highly recommend it.  

I felt this was going completely overboard and that this guy should have spoken privately with the other individual instead of putting the guy on blast in front of everyone.I had a private conversation with the difficult tenant.
