An overview of how the sales comparison approach of appreciating houses works

Find real estate comparisons
When using the sales comparison approach, an agent regards the recent sale of houses with similar characteristics such as the house that is priced. Important factors include:
- Location and neighborhood: Houses in the same neighborhood or subdivision to take into account local market factors and school districts.
- Home style and functions: Looking for houses with similar styles, number of bedrooms and bathrooms and other functions.
- Build quality: Comparing houses with a similar building quality for an accurate comparison.
- Age and state: Finding houses of comparable age and condition.
- Square meters and plot size: Matching houses with a similar home and lottery.
- Recently sold area notifications: Use the most recent sales data that are possible for accuracy.
Make adjustments to comparisons
No matter how many compositions you should choose, you will never find a house that is identical to yours. As a result, even when you use the most similar house, you probably still have to make a few adjustments in the prices on the compositions you find.
Here are some factors that you can use to make adjustments with similar home values:
- Market conditions: The real estate market can change quickly. Even if a similar house was sold just a month ago, the market could have changed since then, which means that you have to apply the similar numbers to explain that.
- Qualities and functions: No two houses are identical. Even in two houses with similar characteristics, one could be worth more. Perhaps a house recently renovated its kitchen or has a more trendy style.
- Location characteristics: Even two houses in the same neighborhood can have different values based on their location. Is one in a busy street while the other is on a quiet dead -end road? Is there a closer to certain facilities?
Analyze weight adjustments
As soon as your broker has completed the comparative market analysis, use a weighted average of the comparable houses to determine the real market value of your house. When you use a weighted approach, you give most of the ways to the houses that look the most on your house, while houses that need more adjustments will have less weight.
