Comparable rents. I can cash flow with all impounds and <20% equity. If I were to liquidate my savings and go in at 20% equity I'd eliminate my MI and cashflow at > $500/mo including all impounds, reserves, etc.
That isn’t including the tax break, principle payment.
I’m not a sophisticated investor, nor am I looking to become a landlord but based on the fundamentals of median home price vs median income, rents vs home prices, cheaper to rent, etc I feel that the market is in a place where it makes sense to own if you can tolerate a small downside risk (5% or so).
