I am overwhelmed by the number of different formulas that are out there for rental property investing and I don't want to overpack for lack of better words my investing formula arsenal so I would like to know what ones are the best to use and whyThe ones I currently use include: COC, NOI (and NIAF), Cap rate, ROR, ROI, and IRR=But I also have heard of NPV, I am also not including any "rule formulas" aka 1% and 50% as those are simply guidelines to follow and not complicated formulasLet me know if I am missing any or don't even need to use some of the ones I am usingThank you,Peyton LaBarbera

Pay the bill yourself, then reimburse yourself by charging the tenants based on a formula.
