Hi forumites! So I got a depreciation report done 6 years ago from Opteon. The house was $500k and built only 2 years prior. The report only included ten years worth of depreciation with the first year being $9k. Sooo I get more experienced and for future reports I went with BMT where the report was for 20 years depreciation and for one of my houses built in 1980 I was able to deduct $7k in the first year. So Im thinking BMT are better, and I want to go back to the first house and get a new report done by BMT. Im hoping the deductions will be greater than the Opteon report and include 20 years. Is this legal and OK?
