Consult with competent real estate experts in that specialize and/or have the ability to analyze market data. Don't use on-line information, free or paid, as it is usually not accurate. Using an expert is well worth the fee paid for their services, and typically will get you more money and value for your property. Tax Assessor information is helpful, yet not accurate as far as market valuation and is not recommended. Good luck!
