Shelley Fortner says: I hoped you could answer a question for me. We are thinking about finishing out our attic into a bedroom. It would add 425 sq. ft. to our home. I had seen where the return on an investment such as this is about 93%. Do you think that it would be more or less of a selling point than adding central air, which we don't currently have. The attic remodel will bring the total square footage of our house to approx. 2650. Thanks for your time.
