When I was buying my house, I had the same question about the pest inspection fee. From what I learned, it's typically not added to the cost basis since it's considered a separate service from the home purchase itself.

However, I found some useful info on https://pestcontrolcompanies.net/ about tax deductions for home-related expenses, including pest inspections. It might be worth looking into for potential savings down the line.

Congrats on the home purchase, by the way!
