I bought my home right before the housing bubble burst. I just tried to refinance and the appraisal listed my house $200,000 below what I paid for it and $140,000 below what I needed it to be for refinancing. My house is one of the smallest in the neighborhood of mostly high-end homes. I'm trying to determine if adding square footage will get the value of my house closer to what I paid for it or if the rate of return for an addition really isn't there. Suggestions from experience or whom I could turn to for advice?
