If I know it, others know it, but they are NOT talking for it is minor (and that would be my opinion, except I have been caught by such "minor" errors by people who jump on such "errors" rather then dismiss them as minor).
Thus double check your data, Wikipedia is a good place to double check data (Wikipedia has errors, some of them are huge, but it is a good place to start).
Just remember housing prices dropped 90% from 1927 to 1938, a fact no one wants to even address today. In some ways it is worse then 90% for in 1934 FDR devalued the Dollar from $20 to an ounce of gold to $35 to an ounce of gold (a value the dollar would retain till Nixon).
On the other hand, houses in 1927 tended to be America Four Square (With Bungalow a distant #2), a large home, not a McMansion but a large home. In 1938 what was building built were bungalow and Ranch style homes (With Ranches replacing the Four Square as the most popular style, it was more compatible with the automobile and cheaper to build).
Most popular were Ranch Style homes (through some four square were also built). Ranch provided about 1/2 to 1/4 the internal space of a Four Square. Thus the 90% price drop also reflected a downsizing of homes by 50-75%.
Using the devaluation of the Dollar, you can claim housing prices drop 95% (the additional 5% attributed to the 40% cut in the value of the dollar with the devaluation to $35 a ounce of gold).
On the other hand, you can say the devaluation was only 25% for people were buying Ranches that were 1/4 the size of the Four Square, thus most of the 90% drop in price reflected a change in housing that was wanted, the Four Square were old Fashioned the Ranch was the design of the future. The problem with that argument is people were buying Ranches for that is all they could afford, where four square were available and people could afford them, they still sold as late as WWII (The problem is the ability to PAY was so reduced that no one had money to buy a four square, so they stopped being built post WWII).
I bring up how housing type change to show how bad the Great Depression was AND how the far right do they best to make it appear less bad then it was.
Would you perfer to live in a Four Square, which can run from a small four square:
To a large four Square:
or a Ranch?
Remember housing resumed in 1938 (housing died in 1927, and did NOT pick up till the Giant Stimulus package FDR did in 1938, you be surprised what was built under the program, it was the program that got the US out of the Great Depression NOT WWII).
I tend to like Four Square, it provides the most internal space, at the lowest cost with the smallest imprint on the land. For those reason it was the most popular housing design from the 1890s till WWII (It derived from Frank Lloyd Wright's Prairie style home, which looks a lot like a Four Square for that reason, the Four Square tends to be a Square unlike the rectangular Prairie and Ranch style homes).
They would have painted George Washington and James Madison as radical left wing extremists and we'd still be under British rule. 
If Fox News were around during colonial times, they probably would have been complaining that King Henry VIII wasn't conservative enough. And our founding fathers would have been painted as brown shirts.
