Real estate valuation: Advantages of an expert opinion using various methods

From the perspective of homeowners, buyers, and real estate agents, there are numerous reasons for conducting a property valuation. Competent appraisers remain indispensable when carrying out the valuation, while reputable service providers offer additional advantages. Three valuation methods are suitable for different requirements when homeowners have a property valued. The result is a report in which the valuation basis is supplemented with comprehensive facts about the property, its location, and the regional real estate market.

Key reasons for a real estate appraisal

A well-founded property valuation enables all parties involved to conduct fair and transparent real estate transactions. This applies to homeowners as well as buyers and real estate agents. With solid facts, every party benefits from security and clarity as soon as private home sellers have a property valued. Even if a sale or other transfer of ownership is not currently on the agenda, a property valuation offers owners important advantages. This is because homeowners need this valuation for a general overview of their assets. If the property owner needs financial resources at short notice, knowing the potential sales proceeds makes it easier to decide on possible marketing plans. Without a thorough property valuation, there is a risk that owners will underestimate the value of their home when selling it and thus miss out on the opportunity to achieve a reasonable sales price. After a quick sale, some property sellers often regret that the property was not carefully valued. While private home sellers assume that the property value is too high, complications can arise during the sale. Excessive prices initially make it difficult to attract interested buyers. This ultimately results in a loss of valuable time, and even after a delayed reduction in the fixed sales price, some prospective buyers may already have been deterred. Property valuation prevents such problems from complicating and delaying a sale. Therefore, well-founded valuations simplify timely real estate transactions with reasonable terms and conditions. Before gifts or an expected inheritance, real estate appraisals provide more clarity about expected tax calculations. At the same time, a valuation report makes it easier for the previous homeowner to divide the property fairly among several heirs or beneficiaries. The objective valuation of a property also enables objective negotiations during the divorce of married owners.

Suitable experts and providers for the valuation of a property

Suitable experts remain indispensable for reliable and well-founded real estate valuation. In addition to civil engineers and architects, trained real estate agents are also suitable for this purpose. It is very important to distinguish between independent real estate appraisers and publicly appointed, sworn, and state-recognized experts. This is particularly important with regard to recognition by courts and authorities. Independent appraisers do not meet the necessary criteria for this. Sworn, publicly appointed, and state-approved experts, on the other hand, need insurance coverage to protect themselves against incorrect real estate valuations. In many cases, owners are better protected if the real estate appraiser is recognized by the authorities. Reputable providers offer an extensive network of experts and additional support for more efficient, secure, and simpler real estate valuation. Such companies contribute to improving the valuation process with innovative software solutions, among other things. Experienced service providers also have access to current market data, which is an important reference point for property valuations. In addition, companies organize comprehensive seminars to train and further educate experts in property valuation. Specialist literature also plays a central role in this, of course.

Three established methods for real estate valuation in Germany

In Germany, there are three established methods for real estate valuation: the comparative value method, the income value method, and the asset value method. Authorities and courts recognize these proven valuation methods. In most cases, appraisers use at least two different methods to ensure an authentic valuation. The comparative value method is based on comparing the real estate with similar properties. A sufficient number of comparable properties is a crucial prerequisite for the application of this method. Comparable properties must have a similar construction and a location of equal value. Experts use this information to calculate average values that indicate the property value per square meter. The determined value can be negatively influenced by individual environmental factors, for example, and positively influenced by modernization measures. The income approach can be used for real estate valuation as soon as the property being valued generates income. This applies primarily to rented properties. Examples include offices, residential properties, and shops with a lease. In the income approach, the income values from rental income are supplemented with the land values of the properties in order to value a property. Appraisers deduct operating costs from annual net cold rents to calculate the net income. To take into account the effects of high property interest rates, experts also include the deduction of land value interest in the property valuation. The remaining useful life and defects in the property also influence the income approach. In the asset value method, the property valuation is based on the question of what costs would be associated with the construction of a comparable building. For used properties, depreciation due to age and the remaining useful life are included in the calculation. In addition, the regional real estate market and local construction prices influence the valuation method. Appraisal committees often determine a real value factor for this purpose, thereby facilitating the property valuation. Property appraisers use the real value method to first determine the building value and the land value separately, in order to add the values together at the end. In addition to the size of the property, other property characteristics such as the year of construction, the living space, and outdoor facilities are relevant for determining the real value.

Important contents of a real estate appraisal report

When homeowners or potential buyers read the corresponding appraisal report after the property valuation, the selected valuation methods and mathematical calculation bases should be presented in a comprehensible manner. Experts justify in the document why a particular method was used to value the property. The appraisal report usually contains a detailed description of the property, including its structural condition. The appraiser's statements are documented with photographs. The infrastructural connection of the property and other local conditions are also usually recorded in the real estate appraisal report. At the same time, the document usually contains information about the local real estate market. Living space calculations, cadastral maps, and regional plans with exterior photos complete a comprehensive appraisal report.

Conclusion: Evaluate real estate using a variety of approaches and individual criteria

With a wide range of approaches and valuation bases, a sound real estate valuation can be individually adapted to properties and locations. Competent experts and suitable procedures result in comprehensive reports that provide real estate owners with neutral and reliable guidance, both in general and in particular in connection with property transfers. Recognition by authorities and courts is often important when owners have a property valued. Small details often have a very beneficial influence on the valuation process.
