I converted my primary residence into a rental property a few years back. For the first year, the house was a rental for 80% of the year so that is what I entered into TT. Essentially all years since then, the house has been 100% business use--I haven't lived in it and I constantly had renters minus a few multi-week gaps between when renters left and new renters arrived. I never thought to update the business percentage field (found under the "Review Information" window at the start of Rental Properties) until this year. Since the actual business usage percentage for last years was 100%, should I update this field this year and any future years (if I end up having mixtures of personal/business usage of the residence)? Or will adjusting this mess up my depreciation calculations, etc?
