I have several contacts in new home construction, architecture, land developers and community organizers who help me locate buyers and sellers.

Is there something like off-market commercial deals where I can search them (like Investorlift or New Western for residential) ? 

They had a search set-up for multi-family and for any single family homes with 4+ bedrooms to see if there were any possibilities of creating a separate living space.

Go search the topic "Lifestyle Asset University" here on Bigger Pockets and you will see a longer thread with a lot of opinions (most are not members) but still worth a read as there are a half a dozen paid members from our group who have commented on that thread.We were formerly called Lifestyle Asset University, but I didn't realize that you couldn't use the word University in your company name here in Utah so we changed our name to Vodyssey. 

The listings @Joel Oh showed weren't in the first 50 listings for my search.

The easiest is doing a search for REI Meetups.

@Keith RichardsonIt depends on your risk tolerance and ability to stay organized.

I’m trying to find a way to get her SSN, any service that provides the SSN search?

You can definitely start your search here on BiggerPockets and connect with agents here.
