This could be beneficial if your initial interest is cash flow!

@Jung Kim, I am having a bit of trouble following the logic here, but I there there are some misalignment of analysis.First of all your analysis isn't adding in the $100k initial equity in the deal.  

Actually, I want to clarify my initial post.

We had a lot of documents in our contingencies and heard crickets from the seller initially in getting them.

What would the timing of initiating a 1031 look like? 

I would have the seller initial or sign something acknowledging your disclosure of agent status. 

I initially wanted to put this equity to work via HELOC or cash-out refi, but I'll just skip to the part where I've decided that I will sell my primary FSBO directly through a title company.

Good point @Stephanie P - "The new loan amount can be no more than the actual documented amount of the borrower's initial investment in purchasing the property plus the financing of closing costs, prepaid fees, and points on the new mortgage loan (subject to the maximum LTV, CLTV, and HCLTV ratios for the cash-out transaction based on the current appraised value)." 

All I have is LLC initial and phone number of person whose real name I came to know from somewhere else.Please help.

Initially, I was thinking that I would like to purchase a small multifamily in the greater Phoenix area.
