Rental Parity II

XXX Presque Isle Lane $153/sqft. Asking $250,000

Yesterday I promised to show an example of rental parity that's already arrived in Chapel Hill. According to IriveRenters criteria, someone looking to either rent or buy this house should buy it. It's a little cheaper to buy than to rent. If it is cheaper to buy than to rent, then rational market participants should snatch up this property. There should be a price floor at rental parity.

So are we at a price bottom? I don't think so.

Today's property may be rented for $1500/month or mortgaged for $1656/month*. Another house a few doors up may be rented for $1600/month so I would guess that the $1500/month rental rate is pretty accurate.

*Assuming a 5.5% 30-year fixed rate mortgage. Accounting for the tax breaks, the total cost of ownership is $1364/month.

The problem is that today's owners couldn't afford the house at that price. They took out a first mortgage with Central Carolina Bank for 80% of the 265K purchase price in 2004. The took out an immediate HELOC to cover another 10% of the purchase price. They put only 10% down but today's buyer will have to put 20% down. In 2008, the owners refinanced their HELOC with Bank of America to $38K. Assuming they fully tapped their HELOC, they owe $249,950, explaining the $250K price tag. Todays sellers can't negotiate lower.

But bad financing aside, why don't I think today's price for this house is the bottom? Because the monthly cost of ownership hinges on a 5.5% interest rate. When interest rates go up, then buyers for this house would have to pay more per month. If you assume that the buyers today and the buyers tomorrow are the same people making the same ammount, then they can't afford a higher payment. Therefore the demand for the house at todays price point lessens. To match the demand for this house, the price must drop.

If you're buying today at a 5.5% interest rate, then 5 years from now when you want to sell to someone who gets an 8.0% interest rate, then the principal has to drop 17%. (Plug 100K as the price for a house with a 5.5% interest rate into the IHB Calculator, the monthly payment is $662. Plug in 83K as the price for a house with a 8.0% interest rate and the monthly payment is $660). Congratulations, you lost 85% of your down payment.

Rule of thumb: You want to buy when mortgage rates are high. You want to refinance when mortgage rates are low.

Remember, you can refinance your interest rate, you can't refinance your principal.
