DSCR terms are simply worse then a conventional loan meaning you will have higher closing costs and likely a pre-payment penalty (which can be even more expensive in the long run then the upfront closing costs).

This is how you really crank your ROI up, making that original down payment work harder for you.When you are in the acquisition phase of a portfolio you should be using other people's money such as mortgage to grow.
