Walk to lifts? That's the definition of High Cost of Living. I would expect that to seem really expensive.
I'm not sure what that last sentence means. In the first years of a mortgage the am is almost all interest. And real cash flow is usually more like monthly expenses + 15% to account for vacancy and maintenance/unexpected costs.
Doubling down on mountain real estate with objectively high prices, political/economic uncertainty and somewhat high interest rates seems crazy talk. Your downside risk is extreme. If the rental stops cashflowing, you are a little fucked. Your home equity is already committed. Most likely, you are either underwater or negative equity on the rental so selling would be painful. And you gotta keep it all rolling so you have a roof over your head.
Generally speaking, that is How Not to Be a Landlord 101. Primary Residence as Collateral, No Geographic Diversification, Minimal Sweat Equity Opportunity due to HOA/Condo and so on. And the financing mechanism is questionable from an underwriting perspective.
In order to get the foot of your neck you either need prices to go up further or cashflow relief from a refi. And over there in the Peoples Republic of Summit County, just expect that your competition is the government. The price to build and carrying cost of all this subsidized housing is insane. If rents or prices trend down, the taxpayers and rental/sales market will get crushed. Go look back at transactions of deed restricted units in 08 and extrapolate that out to now.
If you have money burning a hole in your pocket (which it sounds like you don't) and you want to be a landlord, look at low cost of living areas with strong rental demand. Think College and Company Towns.
