Curious if most people ignore either the interest cost on a down payment loan, or if in all cash, the opportunity cost on that cash. Every calculation model I see seems to discount that part of the transaction when it comes to cash flow. I'm trying hard to find some things that work in a hot market, and the $300 -$400/m in interest on the DP loan is making it tough to hit cash flow targets. I feel I'll never take a dive though without ignoring this. These properties are still positive investments, even with 0% appreciation or increase in rent over 10yrs (4-7% IRR). I figure that's a fair buffer (the 0% appreciation/rent increase) but most have sub $100 cash flow if not a hair negative.
