With the limited resources you have, you want the first investment to not only be a learning experience but to succeed.

With your experience working in building materials this could come easier to you. 

Any recommendation and good experience?

There are many HMLs that will finance new construction, but much of it is based on your experience, credit score, and the expected sale price.

That's my experiences. 

In my experience many unlicensed wholesalers operate in a grey area and often cross over into what is obviously brokering real estate without a license. 

There's obviously quite a bit of diligence that comes after such as who the key principles are and their credentials/track record (both balance sheet and experience), the underlying real estate and thesis behind the investment & tax prep and audit procedures but as a general rule of thumb if the investor can't get past the first part which is understanding what they are investing in, passive investing is probably not for that individual. 

Ask how many units they manage and how much experience they have.

Just be aware that there is an experience requirement for these, as well as reserves requirement (6 months PITI). 

I believe this law presents a great opportunity—not only as a sustainable business model but also as a way to help people in need.However, I have no experience in real estate or foreclosure auctions.
