The main problem that the New Deal addressed was the Great Depression, which caused massive unemployment within the country.
To face the depression, Roosevelt chose to not doing the traditional approach, but he took a gamble to cure the root of the problem heads on.
He created several welfare that created to provide job opportunities for the people, not giving them direct helps. By this opportunities, he gave the people various ways to survive and take care of themselves so they don't have to rely on the government

Muckrakers were the journalists who uncovered corruption in businesses and government.
My answer in regards to the most important factor in house pricing would be: Location.
If the house is located in a bad neighborhood or is simply a large house surrounded by small houses, the value of the house goes does (meaning the price decreases). Also, the average price of the surrounding houses affects the house's price. Example: if you are going to sell your house which is small in a nice neighborhood with large houses, the value (price) will go up on your house.
So in short, location is often a large determination in house pricing.
Hope this helps! :)
