It's a symptom of the current banking system. Things for which loans are made (homes, autos, schooling, etc.) are artificially price-hiked.
The interest is lower and payback is slower in a fractional reserve paradigm, but people afford payments not interest rates. This causes the total price to go way up, but the monthly remains what they might afford. Later, after turning homes into business investments and boostingthe prices, the down payment just becomes too much. Even the advent of the 3.5% down causes the total to rise for the same reason.
Fractional reserve isn't possible with hard money, so bitcoin will also fix housing costs.
