I got a conventional loan with 5% down, 30yr and took a 4.25% vs a 3.75% to receive about 2500 back in lender credits on my down payment. 

My two issues were the down payment for a 80/20 commercial loan and also being able to move on to the next deal sooner than later.

Also make it sellable.Then looking to take the cash leftover after paying off existing loan, to make a down payment on another house or two.

You may also need to show proof of your down payment and closing costs, depending on how awake the selling agent is.

Never had issues with late/missed rent, but I ended up offering cash for keys after about a year because I found there were a lot of headaches unrelated to rent payment - noise, unreasonable maintenance upgrade requests, no respecting communication boundaries, etc.

I have a very motivated seller who wants to sell her house as she is late on her mortgage payments ,owe HOA and back taxes. 

I have had the property and been making payments for about 3 years.

That being said, I'm compulsive and manage just 1 extra mortgage payment in principle per year.

One analyzer adds the CC to the total purchase price of the building, then subtracts the down payment (25%) from that amount and then calculates the monthly payment.
