For an unbiased analysis of what their home would be worth both before and after an improvement project, a homeowner can work with a professional real estate appraiser — such as a Designated member of the Appraisal Institute — to conduct a feasibility study. During a feasibility study, the appraiser will analyze the homeowner’s property, weigh the cost of rehabilitation and provide an estimate of the property’s value before and after the improvement. Some green and energy-efficient renovations, such as adding Energy Star appliances and extra insulation, are likely to pay the homeowner back in lowered utility bills relatively quickly. Lower utility costs also are a draw for potential homebuyers. When appraising a home, the appraiser evaluates local supply and demand for green and energy-efficient properties and features. The Appraisal Institute offers a free, informative brochure titled ” Remodeling & Rehabbing ,” which provides consumers with valuable advice on home remodeling.
