Analysis
To do the research and analysis for pricing, you can use websites like zillow.com and filter results to be similar to your property and to see only sold properties. From there you can compare the similar properties that have sold, and adjust the price based on your added features or lack thereof.
This isn’t an exact science and it works best in neighborhoods where owners buy and sell more often, and in homes that are similar in style and size to other nearby homes. If you have a unique home in a unique location (like a custom waterfront home for example), it becomes more difficult to price, but a proper analysis is still the key.
