About Affton, Missouri
Affton is not a city. It is an unincorporated area of St. Louis County (a Census-designated place), so it has no city government of its own. About 81% of homes are owner-occupied and 83% are single-family detached.
Most of the housing went up in the postwar decades: the median home was built in 1958, and about two thirds were built from 1940 to 1969. For buyers that means established streets of postwar homes, often with updates worth weighing into the price.

“Craig is an awesome agent he showed me over 30 houses and was patient with me for over a year while I searched for my first home. He's extremely knowledgeable and does not put any pressure on his clients to purchase something they don't want just to make a sale. I highly recommend him 💪 reply Reply”

“Both bought and sold a property through Craig recently. The buying was a struggle because of the crazy market, but Craig helped immensely in the process, both by keeping our spirits up and making sure we weren't settling. He has some true integrity in that I honestly feel like he was not just looking to make a sale, but was wanting to make sure that we found the ideal house for us. As for the selling side, everything went smoothly. Everything was planned out and executed on time. I would absolutely use Craig again for any further moves, but this is likely going to be our forever house.”
