A Cost Segregation study may be performed at any point during the buying, redesign, or construction of a building. The ideal time to do a analysis is during the period the building is built, purchased, or renovated. When the property's framework is established, it's the best time to think about a Cost Segregation study for developers who are in the preparing stages of construction or remodelling. Ask Sigma Valuation Consulting in the U. S. if you're searching for cost segregation solutions as well.
