If you're making any kind of financial decision and the value of your home is relevant, you'll want a full appraisal. When selling your home, an appraisal will help you determine the most appropriate price. When buying, be sure you're not overpaying by getting an independent appraisal. If you're engaged in an estate settlement or divorce, it ensures that property is divided fairly. A home is often the single, largest financial asset anybody owns. Knowing its true value is essential to making the right financial decisions.
