This is a good first start, but won't work for everyone. E.g. we got a new roof with solar. The solar is tax deductible. But is the roof? My options are (a) no (b) the portion with solar on top (c) all. Asking around, different people have taken different options, and no option is un-taken.
Option (c) will probably never get audited and we all know it. I won't be taking it.
