I am appraising an existing house, that will be expanded and renovated. The expansion/renovation has not begun. The appraisal will be done "subject to" completion. Which box in the Improvements section do I check: 1) Existing; 2) Proposed; or 3) Under Const.? The house does exist, but the appraisal is subject to the proposed renovation/expansion, so it appears that both apply, however, I obviously can't choose both. Thank you all for your help!
