Your response led me to Googling the difference between NWROI (Net Worth Return on Investment) and Cash on cash and it yielded the following distinction: "Cash on cash return measures how much cash an investment property will actually generate, whereas ROI measures total wealth buildup"So my takeaway is maintaining a positive cash on cash return over prioritizing concern for ROI in order to accrue enough funds to put a down payment on a non-FHA loan for the second property

A few additional notes: If a borrower stops paying for whatever reason, you will need to consider that property taxes will accrue and become the responsibility of whoever takes ownership at the foreclosure auction.You should already have yourself named as mortgagee by the insurance company, and have Evidence of Insurance showing that, but you may have to keep the insurance premiums up if the borrower stops paying it.

Many loans have language which allows the advances to become a part of the principal balance and accrue interest at the note rate.
