What goes into an appraisal?

A home purchase is the most significant investment most of us could ever encounter. It doesn't matter if it's where you raise your family, a seasonal vacation home or a rental fixer upper, purchasing real property is a complex transaction that requires multiple people working in concert to pull it all off.

It's likely you are familiar with the parties taking part in the transaction. The real estate agent is the most recognizable person in the transaction. Then, the lender provides the financial capital required to finance the transaction. The title company ensures that all aspects of the sale are completed and that a clear title transfers to the buyer from the seller.

So what party is responsible for making sure the property is consistent with the purchase price?   This is where you meet the appraiser.   We provide an unbiased opinion of what a buyer could expect to pay - or a seller receive - for a property, where both buyer and seller are informed parties. A professional Arizona licensed appraiser from Shannon Appraisal Service will ensure you as an interested party are informed.

Appraisals begin with the home inspection

Our first task at Shannon Appraisal Service is to inspect the property to ascertain its true status. We must actually see features, such as the number of bedrooms and bathrooms, the location, living areas, etc., to ensure they truly exist and are in the shape a reasonable person would expect them to be. To ensure the stated square footage has not been misrepresented and illustrate the layout of the property, the inspection often requires creating a sketch of the floor plan. Most importantly, the appraiser looks for any obvious features - or defects - that would have an impact on the value of the house.

Following the inspection, an appraiser employs two or three approaches when determining the value of real property: sales comparison and, in the case of a rental property, an income approach.

Cost Approach

This is where the appraiser uses information on local construction costs, labor rates and other elements to derive how much it would cost to construct a property similar to the one being appraised. This figure often sets the upper limit on what a property would sell for. It's also the least used predictor of value.

Analyzing Comparable Sales

Appraisers are intimately familiar with the communities in which they appraise. We innately understand the value of particular features to the residents of that area. Then, the appraiser researches recent transactions in close proximity to the subject and finds properties which are 'comparable' to the subject at hand. Using knowledge of the value of certain items such as fireplaces, room layout, appliance upgrades, extra bathrooms or bedrooms, or quality of construction, we add or subtract from each comparable's sales price so that they more accurately portray the features of subject.

  • Say, for example, the comparable has an irrigation system and the subject does not, the appraiser may subtract the value of an irrigation system from the sales price of the comparable.
  • If the subject property has an extra half-bathroom and the comparable does not, the appraiser might add an amount to the comparable property.
An opinion of what the subject might sell for can only be determined once all differences between the comps and the subject have been evaluated. The sales comparison approach to value is most often awarded the most weight when an appraisal is for a real estate exchange.

Valuation Using the Income Approach

In the case of income producing properties - rental houses for example - we may use an additional method of valuing real estate. In this scenario, the amount of revenue the real estate yields is taken into consideration along with other rents in the area for comparable properties to derive the current value.

Coming Up With the Final Value

Combining information from all approaches, the appraiser is then ready to put down an estimated market value for the subject property. The estimate of value at the bottom of the appraisal report is not necessarily the final sales price even though it is likely the best indication of what a property could sell for in an open market. There are always mitigating factors such as the seller's desire to get out of the property, urgency or 'bidding wars' that may adjust the final price up or down. But the appraised value is often used as a guideline for lenders who don't want to loan a buyer more money than they could recover in case they had to sell the property again. At the end of the day: An appraiser from Shannon Appraisal Service will help you discover the most accurate property value, so you can make profitable real estate decisions.
