Should I buy a house because Mortgage rates are low
How can people afford 10% mortgage? Part of the history of housing prices was the non-bubble component of the bubble. To be clear, there was a housing bubble and crash. Let me offer some simple math to illustrate my point -  This is what happened on the way down. A middle class earner, $60K/yr couple, using 25% of their income, the normal percent for a qualified mortgage, was able to afford $142K for the mortgage payment. At 10% fixed rate. This meant that after down payment, they were buying a house at $175K or so, which was above median home pricing.  Years later, obviously, this wasn't a step function, with a rate of 4%, and ignoring any potential rise of income, as in real term, income was pretty stagnant, the same $1250/mo could pay for a $260K mortgage. If you want to say that taxes and insurance would push that down a bit, sure, drop the loan to $240K, and the house price is $300K.  My thesis ('my belief' or 'proposal', I haven't written a scholarly paper, yet) is that the relationship between median home price and median income is easily calculated based on current 30 year fixed rate loans. For all the talk of housing prices, this is the long term number. Housing cannot exceed income inflation long term as it would creep up as a percent of income and slow demand. I'm not talking McMansion here, only the median. By definition, the median house targets the median earners, the middle class.  The price increase I illustrate was just over 70%. See the famous Shiller chart -  The index move from 110 to 199 is an 81% rise. I maintain, 70 of that 81 can be accounted for by my math. Late 80's, 1987 to be exact, my wife got a mortgage for 9%, and we thought that was ok, as I had paid over 13% just 3 years earlier.
