Easy money reflating house prices
My colleague Chris Swann says to beware of housing false dawns. I couldn’t agree more. While the pace of decline in house prices moderated in April, one has to consider the stupendous monetary stimulus that helped drive that improvement. With rates about as low as they can go, the only way to drive a sustainable increase in prices is to increase buyers’ income. With the employment picture continuing to deteriorate, don’t look for rising incomes any time soon.

The chart above plots the month-over-month change in the composite 20 index compared to average 30-year fixed-rate mortgages.
Bulls would point to an improvement in the so-called “second derivative,” a decline in the rate of decline. From March to April prices dropped only 0.6%, far better than the 2%+ declines each of the prior six months.
Bears would argue that the data showed a similar increase a year ago, and then promptly turned back down.
But prices have fallen 18% since last year, bulls might say. They can’t fall forever.
The trump card, however, falls to the Bears in my view: Mortgage rates are 110 basis points lower today than they were just last fall. That’s a lot of monetary stimulus.
When rates go down, prices go up (all else equal). A quick present value calculation shows that a $3,000 monthly payment can pay off a $500,000 30-year mortgage priced at 6%. Drop rates to 5% and that same monthly payment will support a $558,000 mortgage.
Admittedly, this is a simplistic way to look at house prices. But it serves to show how incredibly sensitive they are to interest rates.
But low interest rates, along with lending structures that allow people to borrow more relative to their income, only offer a temporary sugar high for house prices. There won’t be a sustainable increase in prices until there’s a sustainable increase in buyers’ income. And that’s not happening any time soon, not with unemployment speeding towards double-digits.
