@Albert Bui Thanks for breaking it down - that makes a lot of sense. You are right when you think about the margin of error. Given the houses I've been looking at this is the difference between making something marginally acceptable and unacceptable, so its good to understand the "wiggle room" I have.
@Hattie Dizmond Curious to know, if your ICC is ~7.5%, does that mean that is the minimum ROI (or cash on cash return) that a house needs to be in order for you to consider it? All around, I agree that an appropriate discount rate should be the ICC/Opportunity Cost, though someone like myself doesn't really have that - I guess I can consider my Roth 401(k) return as my personal hurdle rate.
@Roy N. I've been looking at cash flows from the following two perspectives:
1 - Cash in, less cash out, less allowances (this includes P&I, taxes, all expenses, plus all allowances ~10% vacancy, 10% prop management, 5% repairs).
2 - 50% rule - so NOI, compared to P&I.
i think in both of the scenarios above, the P&I component ends up being an indicator of cash flow (assuming that we aren't purchasing a property where the rents are nonexistant). Would you agree?
Side question Roy, what kind of CAP reserves do you have? Are these the same as CapEx reserves?
