Both working okay/fine paying jobs, both worked through school so no student debt, driving old cars so no car payments

For a  300 K in Tampa Area what would be the down payment?

I google free mortgage calculator to see what my payments will be.

Been thinking about taking on a personal loan of 50-70k for purchasing power in my Midwest market, the loan would just be for down payments and closing costs on sub 85k SFH / Duplex properties.

Also, make sure you consult with a trusted lender to give you all the best options based on your goals & current scenario.

These are mainly meant for first-time investors with low reserves, and you end up making a much lower profit margin due to the extremely high interest payments.  

I can't have a re-inspection done yet, because the tenant is delinquent in her payments, so the only way to move forward, it seems, is to have her evicted now.

The car company is going to repossess the car if payments are not made.  

I am an out of state note investor, and have a note that is held in my companies 401K Trust, where a neighbor is suing the borrower in small claims court.   

It's great that you already have an agent connection, but It will take time to build those other trusting relationships and familiarize yourself with a new market.
