Hi Sam, I noticed you posted this question a while ago, but that it has gone unanswered. The Richland airport is used by mostly single-engine planes, so noise is at a minimum. The main airport for the Tri-Cities is located in Pasco.
On a side note, I have seen that home in person - lots of space in the finished basement, with tile flooring and a large utility room. The house could generally use a little TLC, but it's a great investment home!
Please let me know if there are any further questions I can answer for you. -Jennifer
