Real Property Appraisals: A Primer

Buying a house is the most significant transaction some of us might ever consider. It doesn't matter if a main residence, a seasonal vacation home or one of many rentals, purchasing real property is a complex transaction that requires multiple people working in concert to see it through.

Most of the people participating are quite familiar. The most known person in the exchange is the real estate agent. Then, the lender provides the money necessary to fund the transaction. The title company ensures that all details of the sale are completed and that the title is clear to transfer to the buyer from the seller.

So, what party is responsible for making sure the real estate is worth the amount being paid? In comes the appraiser. We provide an unbiased opinion of what a buyer might expect to pay — or a seller receive — for a property, where both buyer and seller are informed parties. A licensed, certified, professional appraiser from Isabella Cortesi will ensure, you as an interested party, are informed.

Inspecting the subject property

To ascertain the true status of the property, it's our responsibility to first conduct a thorough inspection. We must see aspects of the property first hand, such as the number of bedrooms and bathrooms, the location, living areas, etc, to ensure they truly are there and are in the shape a reasonable person would expect them to be. The inspection often includes a sketch of the property, ensuring the square footage is accurate and conveying the layout of the property. Most importantly, the appraiser looks for any obvious features - or defects - that would have an impact on the value of the house.

Once the site has been inspected, an appraiser uses two or three approaches to determining the value of the property: a paired sales analysis, a replacement cost calculation, and an income approach when rental properties are prevalent.

Cost Approach

Here, the appraiser analyzes information on local construction costs, the cost of labor and other factors to ascertain how much it would cost to replace the property being appraised. This estimate usually sets the upper limit on what a property would sell for. The cost approach is also the least used method.

Sales Comparison

Appraisers get to know the subdivisions in which they appraise. They thoroughly understand the value of specific features to the people of that area. Then, the appraiser looks up recent sales in the area and finds properties which are 'comparable' to the property at hand. Using knowledge of the value of certain items such as upgraded appliances, extra bathrooms, additional living area, quality of construction, lot size, we adjust the comparable properties so that they more accurately portray the features of subject.

For example, if the comparable property has an extra half bath that the subject doesn't, the appraiser may subtract the value of that half bath from the sales price of the comparable.
In the case where the subject has something such as an extra half bath that a comparable doesn't have, the appraiser might add the value of that bath to the comparable property.

Once all necessary adjustments have been made, the appraiser reconciles the adjusted sales prices of all the comps and then derives an opinion of what the subject could sell for. At Isabella Cortesi, we are an authority when it comes to knowing the worth of particular items in San Francisco and San Francisco County neighborhoods. The sales comparison approach to value is commonly awarded the most consideration when an appraisal is for a home purchase.

Valuation Using the Income Approach

In the case of income producing properties - rental houses for example - we may use a third approach to value. In this case, the amount of income the real estate generates is factored in with income produced by nearby properties to give an indicator of the current value.

Putting It All Together

Examining the data from all applicable approaches, the appraiser is then ready to document an estimated market value for the subject property. The estimate of value on the appraisal report is not always what's being paid for the property even though it is likely the best indication of what a property is worth. There are always mitigating factors such as the seller's desire to get out of the property, urgency or 'bidding wars' that may adjust an offer or listing price up or down. Regardless, the appraised value is typically used as a guideline for lenders who don't want to loan a buyer more money than the property is actually worth. The bottom line is, an appraiser from Isabella Cortesi will help you discover the most accurate property value, so you can make the most informed real estate decisions.
