I personally don’t prefer paying more than $35K for $600 rents.

I also wouldn't consider that part of my investment because I'm actually not taking money out of my pocket to pay it down. 

I have an agent marketing the property but it does not seem to be listed on many sites.

I'd like that to be financed as well somehow, and it seemed to me like a private lender would be the best way forward for that, but all the profit on the BRRRR is stuck in the deal as equity, so paying the private lender back seems challenging to me. 

Especially if you are willing to pay 5% already.

Pay them back.

There's going to be a learning curve but as you progress down the host road you'll learn what's needed to minimize your time needed on site.

Seller is paying the buyer's broker at closing (ME) $8250 and 'contributing' another $8250 towards buyers closings costs.
