What are these house types: bungalow, foursquare and farmhouse?

Dear Agent Alice,
I’m beginning the search for my first house. What are these house types: bungalow, foursquare and farmhouse? What about all those colonials and capes?

Dear New Buyer,
Excellent question. There are standard descriptions but the details vary by region and period. Call me and I can show you examples of each.
