Housing Pricing Structure in Mid-City

Sales of single-family houses have been brisk in Mid-City this year. This has been especially true in older, more established neighborhoods, where housing is relatively inexpensive compared to the new homes being built in the newer neighborhoods. Nevertheless, there are also many families who are willing to pay a higher price for the prestige of living in one of the newer neighborhoods.

The file below contains data on 128 recent sales in Mid-City. For each sale, the file shows the neighborhood (1, 2 or 3) in which the house is located, the number of offers made on the house, the square footage, whether the house is made primarily of brick, the number of bathrooms, the number of bedrooms, and the selling price. Neighborhoods 1 and 2 are more traditional neighborhoods, whereas neighborhood 3 is a newer, more prestigious neighborhood.
