I'll shoot you a private message.

We just need to verify that you have cash for the downpayment, closing cost, and up to 6 months of the mortgage payment as reserves.

Having the ability to offset their mortgage with an ADU would be a game changer. 

When you sign almost all mortgage closing packages, you are signing an Occupancy Clause that states you are intending to live in the home for 12 months.  

You’ll want to find a reliable mortgage agent, property manager, and handyman.

I know that I can either save the money(which I have via cash and line of credit), I can refinance the property with the bank for all or a portion of the amount I owe the seller, or I can get private money to take on a note and pay back the seller.My goal is to get private money.

You should be able to claim the ENTIRE mortgage interest as they let you on primary homes.

Most mortgage companies will not call loan due if payments are current but you do run that risk and need to be prepared to payoff or refi at a moments notice.

I have found 1st lien mortgages to be very profitable.

This is a conventional loan where they also cover your PMI (private mortgage insurance).
