Seller will continue to complete rehab and take on project as their own now.What type of paperwork would I need to engage this first position mortgage - debtors will be an LLC and personal guarantees of two people.

Engage with the responses and aid you are receiving already.   

I’ll for sure engaged for additional guidance.

There is no compensation for the Realtor on the front end and the back end (rehab) will be handled by someone other than the wholesaler so no guarantee there either.Sure, you may want to engage a Realtor for a small fee to give you advice and input on whether the particular property is priced right for a wholesale deal.  

There are also a number of syndicators that hold web sessions and you can join online.

For instance, if the lender doesn't receive more than $600 in interest, and/or is not engaged in the "trade or business of lending money" (i.e. some private lenders), then they're exempt from the requirements of filing a 1098. 

I would engage the services of a knowledgeable advisor.

My favorite part is all the people I get to talk to and interact with, so much different from my head-down professional life.After a few months of scouting a dozen cities to potentially invest in, I picked Milwaukee, not because it was the best place to invest but because it was the first place I got a realtor to engage seriously and start sending me decent leads that matched what I described in my intro.I like to send out 1-2 offers per week even if I don't think they will be accepted, as long as the price would make it a great deal. 

I personally would have to see a lot of "social proof" for something this before I'd devote any money to it as a subscriber, but I think through some on-point marketing and a strong UX/UI (think Lemonade Insurance's user interface) it would be a great business stream with lots of front-end and back-end revenue potential.I think BP would be a killer spot to promo something like this, as something with a engaging UI and that has your coaching mind poured into it would be a great tool for any beginner or "stuck" investor looking to take steps.

@Tab Teehee If the purpose is to find out about equity and credit lines, then it's best to engage an appraiser to come and give you a value for the asset, which can then use as leverage when speaking to banks or mortgage brokers.
