One of the most valuable tools that any seasoned investor can have at their disposal is seeing what properties recently sold, as they provide some of the best data for underwriting a deal. Transactions recently have been so hot that the data wiz kids who follow things like the market value of apartments or investments in apartment buildings are now making headlines. The data is useful for valuing and comparing, making predictions, and negotiating. Look up completed sales data — be it when expanding a commercial portfolio or researching industrial property for sale; reviewing actual sales data provides a sounder basis from which to devise informed and, ideally, risk-reducing investment strategies that will help prospective buyers identify properties with strong growth and income potential.
