"The real estate market collapse of 2006-2009 led to record low mortgage rates. History shows the rates will probably rise again in the future."

When interest rates rise house prices will be pushed down.

"in the 40 years from 1970 until 2010, the 30-year mortgage rate was above 10 percent for almost 11 years. The rate was between 8 and 10 percent for an additional 11 years. That gives 22 years of rates over 8 percent out of the 40-year period."

We are living in a fake interest rate environment. It will not last forever. When it ends house prices will be pushed lower to meet buying power. Normal interest rates are at least 8% for a mortgage. Consider this before buying a house at low rates.

A 30 year $100,000 mortgage costs $491.94 a month at 4.25%.
A 30 year  $67,000 mortgage costs $491.62 a month at 8.00%
A 30 year  $56,000 mortgage costs $491.44 a month at 10.0%

That changes house prices as buying power evaporates unless incomes rise greatly.
