This is usually not the case as the value placed on a property is much more determined by other factors than remodeling, making home improvements and maintenance.
A great factor that determines the value of a property is the fair market price. The fair market price is the price a buyer is willing to pay for the purchase of the property and the price the seller is willing to accept for the sale of the same property.
Determining the fair market price involves finding the values of properties in the same subdivision which are very similar to the property being put up for sale. This similarity could be in terms of the property type, condition, number of floors, property square footage etc. These very similar properties are called comparables.
There are some cases where the exact comparables are not found for the property. In such instances, sales of properties which are similar but not exact can also be used as comparables.
In other to be able to compare this comparable sale to the property and bring them to the same level, net adjustments for differences are calculated in terms of the factors that affect the value which could range from difference in square footage , floors, amenities, house condition and view of the property.
Whether you are the buyer or the seller of a property, it is always advisable to seek the services of a professional to help determine the asking or the selling price unless you are versatile in that field and have carried out proper research.
