A home purchase is the largest, single investment most people will ever make. Whether it's a primary residence, a second vacation home or an investment, the purchase of real property is a complex financial transaction that requires multiple parties to pull it all off.
Most of the people involved are very familiar. The Realtor is the most common face of the transaction. The mortgage company provides the financial capital necessary to fund the transaction. The title company ensures that all aspects of the transaction are completed and that a clear title passes from the seller to the buyer.
So who makes sure the value of the property is in line with the amount being paid? There are too many people exposed in the real estate process to let such a transaction proceed without ensuring that the value of the property is commensurate with the amount being paid.
This is where the appraisal comes in. An appraisal is an unbiased estimate of what a buyer might expect to pay - or a seller receives - for a parcel of real estate, where both buyer and seller are informed parties. To be an informed party, most people turn to a licensed, certified, professional appraiser to provide them with the most accurate estimate of the true value of their property.
So what goes into a real estate appraisal? It all starts with the inspection. An appraiser's duty is to inspect the property being appraised to ascertain the true status of that property. He or she must actually see features, such as the number of bedrooms, bathrooms, the location, and so on, to ensure that they really exist and are in the condition a reasonable buyer would expect them to be. The inspection often includes a sketch of the property, ensuring the proper square footage and conveying the layout of the property. Most importantly, the appraiser looks for any obvious features - or defects - that would affect the value of the house.
Once the site has been inspected, an appraiser uses two or three approaches to determining the value of real property: a cost approach, a sales comparison and, in the case of a rental property, an income approach.
