I imagine there is not much of a relationship with the turnkey service after the sale and I would deal with the PM and Loan company directly. 

Seriously though, if you haven't already get your self a solid real estate-focused tax professional in your corner.

After you get that first one, I would start looking for BRRRR strategy, and if you have time to market direct to seller you can try to negociate seller financing and sub to deals. 

I have one rental property that I have been self managing for about 10 years but I'm looking to exploring and potentially doing my first Flip this year. 

hyper forcus on one area and go under contract directly with the sellers.

Each individual cell you set up within the Series LLC would be owned by you directly, qualifying each cell for the FONCE exemption. 

If I understand correctly; the seller would receive 80% ($40,000) directly from the mortgagee at closing and would enter into a personal agreement with me for the 20% down payment ($10,000) in which he would be reimbursed separately from my mortgage payments at a separately agreed upon rate and term?

As long as the wholesaler is direct with the seller and the deal is real, go for it.

Sellers often favor buyers who can make larger down payments, as it indicates stronger financial backing and reduces the risk of the deal falling through due to financing issues.Additionally, SFH properties are more accessible to a wider range of buyers, including first-time homebuyers and families, which can lead to less direct competition from institutional investors.

Together with the equity that the house will have (heloc or refinance).No one has provided details to knocked down the idea yet, so I'm leaning in the doable direction.
