During the great depression foreclosure rates skyrocketed. what was the main cause?

This happened when during a time of bad economic stage in the US which was the great depression of the 19229  many farmers borrowed money from the bank so they could buy land and tools to work on it. They did not have another choice than to pledge their last things of value and when they could not pay the loan for their lands the banks just took back their lands and sold them in order to get back their money. 

Explanation:

The great economic depression that occurred around 1929 and 1932 was highlighted by a marked fall in stock prices and the struck of Wall Street. This was a worldwide economic issue that brought unemployment that risen from 8 to 15 million (173 of the non-farmer workforce). 40% of the farms in Mississipi were on the AUCTION block. Farmers in Midwest were hit more powerfully by economic slides. Farmers refused to auction (or publicly held sale at which their properties were sold to the highest bidder. Many farmers borrowed money from the bank to buy land or machinery, they pledge their ASSETS as security on the loan. So when a farmer could not make the payment on a loan for his land, the bank could take back his land and sell it to get back their money.
