Some people look at the value of a house based on the price per square footage. This is not always the most accurate way to look at the price of a home. Say you have 2 homes that are next door to each other and they are the exact same square footage. One has 3 bedrooms and one has 4. The one that has 4 bedrooms is going to have a higher price per square footage than the one that has 3 bedrooms because an extra bedroom increases the value of the house.
Most homes in the neighborhood should have a similar price per square footage, but there will be small variations based on how many bedrooms, baths, etc. One of our agents will be happy to look at the comparable homes in the neighborhood to let you know how the home you are interested in compares with the others.
