@Quinton Brown Sorry, I was asking @Michael Santeusanio more about the components of "Debt Service". With HMLs, it's usually just PITI (plus HOA, if there is one). With banks/CU's, their DS also includes property management, maintenance, etc.
@Michael Santeusanio On DSCR loans, lenders start introducing interest rate reductions at >1.25x DSCR, so that would be a good indicator that threshold is risk mitigating; therefore a good benchmark.
