DSCR only requires that the rents be equal to or greater than the PITI payment or the ITI payment if you go I/O interest only.You can use DSCR for a cash out refinance, Purchase and even a "Rate and term" which is when you want a lower rate or get out of a HML - Hard Money Loan, Balloon payment, Adjustable rate getting ready to expire/adjust (Recast).
