Should I Add-On to My Existing Property, or Move?

This is a question that many people are faced with: should we add on to our existing home or should we sell our house and buy a new home? The question can be perplexing but, with a little analysis, one can arrive at a logical solution.

There is a principle in real estate appraisal called conformity that says that all homes in a given area should be of similar size and value. If you add on to you home and, in effect, overbuild the neighborhood, the value of the smaller homes will bring your value down regardless of how much you have invested in the property.

If you plan to stay in your home for a long time, then you should be able to enjoy the addition and thereby recapture the cost regardless of whether it brings any additional value to the property when it sells.

Another difficulty that homeowners face when making an additon to their home is creating what appraisers call functional obsoloscence. For example, if an additonal family room or bedroom causes an unconventional floorplan, the new room could be functionally hampered and thereby affect value.

Contractors will advise people that an additon has to be of significant size to spread the cost of possible additonal heating, air-conditioning, and foundation work. Many times a small room addition may cost as much as a larger one.

Certain room conversions can actually lessen the value of a property. For instance, converting a two car garage to a family room will usually lower the value of a home and could hurt its marketability. People expect a home to have a garage and, even though the additional living space is nice, it still needs the garage.

Once a home gets to a certain square footage, prospective buyers expect different types of amenities in the kitchens, bathrooms, and all throughout the home. Unless updating occurs at the same time as the addition, these things will be outdated.

Many times homeowners are better off selling their existing home and buying another home. If the homeowner decides to make an addition, careful attention should be given to all the considerations mentioned above. Good third-party advice can be invaluable.
