The value iof a property is based on a number of variables:
First, there is wholesalel. In most cases if you need to sell quickly, the value will be less, say if an investor purchased the property at wholesale, which typcially is about 10-20% below retail.
Second is the price someone looking for property in the area would pay. Someone that knows the local values, is qualified to buy, and is looking for a fair price.
Third is your Fair Market Value. This value is based on the amount of time and evergy you have to get the maximum value out of the property.
Proper preparation, including cleaning, painting, decluttering, staging, making necessary repairs, all go into Fair market value.
