The sales comparison approach is based primarily on the principle of substitution. This approach assumes a prudent (or rational) individual will pay no more for a property than it would cost to purchase a comparable substitute property. The approach recognizes that a typical buyer will compare asking prices and seek to purchase the property that meets his or her wants and needs for the lowest cost. In developing the sales comparison approach, the appraiser attempts to interpret and measure the actions of parties involved in the marketplace, including buyers, sellers, and investors.
Remember this: appraisers are looking at the condition of what’s permanently part of or attached to the house. They’re not evaluating the décor or furniture or anything that’s not affixed to the property; what’s most important are your home’s physical characteristics (age, square footage, the number of bedrooms and baths, lot size, location, view) as well as their observable condition.
The cost approach was once called the summation approach. The theory is that the value of a property can be estimated by summing the land value and the depreciated value of any improvements. The value of the improvements is often referred to by the abbreviation RCNLD (for "reproduction/replacement cost new less depreciation"). Reproduction refers to reproducing an exact replica; replacement cost refers to the cost of building a house or other improvement which has the same utility, but using modern design, workmanship and materials. In practice, appraisers almost always use replacement cost and then deduct a factor for any functional dis-utility associated with the age of the subject property. An exception to the general rule of using the replacement cost is for some insurance value appraisals. In those cases, reproduction of the exact asset after a destructive event like a fire is the goal.
If your loan is a conventional loan, then it is subject to the rules of the Home Valuation Code of Conduct (HVCC). Barb Torres, an accredited senior appraiser says, "As soon as the parties find an appraiser is coming out who is not familiar with the local market, they have every right to contact the lender (preferably in writing) to DEMAND a local appraiser be used."
Land and improvements are treated separately. German GAVP assumes that the land can be used indefinitely, but the buildings have a limited lifespan; This coincides with the balancing of the assets. The value of the land is determined by the sales comparison approach in both the income and cost approaches, using the data accumulated by the Gutachterausschuss which is then added to the building value.
In order to account for the usage of the land, the net operating income is reduced by the Liegenschaftszins (interest paid to the land-owner by the owner of the building, i.e., ground rent). The Liegenschaftszins is the product of the land value and the Liegenschaftszinssatz (interest rate for land use). The Liegenschaftszinssatz is the equivalent of the yield—with some important differences—and is also determined by the Gutachterausschuss.
"What is my house worth?" These real estate appraisers can answer that and much more all over Pinellas County. Whether it is appraising your home for a property tax appeal if your property taxes are too high, valuing your home for estate work or a divorce or helping you secure a HELOC, a local appraiser is best. They obviously also appraise new construction homes as well as existing homes, and can do it for a home listing, before or after a sale. They use the local MLS (Multiple Listing Service) to gather data on sales and listings and use them to professionally tell you what the price per square foot should be for your home and others in your area. They also can determine if there's any effect on the value of your home from pending foreclosures, REOs, and other "short sales" in Pinellas County. A licensed and certified appraiser's estimates of value on residential single family homes, condos, townhouses and more are much better than what you'll find when using an AVM (automated valuation model) or a BPO (Broker Price Opinion). They can do an appraisal for VA, FHA, conventional, jumbo, and Fannie Mae or Freddie Mac purposes, and routinely provide those reports on URAR, drive-by, and 1004 MC (1004 Market Condition) forms as well as others.
