......do I need to add up all these receipts to get the basis? Another option might be to use the taxable value from the local appraisal district when it was completed.
Yes, add up all of the receipts for the costs to construct the house plus the cost of land and improvements made over the years to arrive at your basis.
Do not use the valuation assigned by the county (or local) appraiser, which is only used for the purposes of real estate taxation.
