Investing in upgrades can always help in regards to selling a home. We recommend that you definitely discuss possible renovations with an experienced broker---this could increase marketability and the selling power of your home. Correcting deficiencies in your home can make sellers see the property more favorably--and makes them willing to pay a higher price. After all, renovations and upgrades can help to increase the listing price of your home--and that is great for you, especially in a seller's market like Boston, where supply is low and demand is high!
"- Energy efficiency upgrades and/or replacements that will reduce utility bills (i.e.boiler/furnace replacements) or enhance comfort (i.e. insulation). Replacement windows enhance comfort in addition to conserving energy. These improvements make a home's resale more appealing and begin to pay back their cost almost immediately. There are also rebates, tax credits and incentives available from time to time. - Cosmetic upgrades (i.e. paint, siding or hardwood floors) that are often done when ongoing home maintenance is required, but just as often done to personalize the property to the owner's taste. When done as part of the maintenance cycle, some of these projects don't cost as much out of pocket and some of them (i.e. paint or siding) prevent potential damage. - Lifestyle and convenience modifications and additions (i.e. adding bathrooms, closets or living space) often done to better suit the lifestyle or needs of homeowners. These are often big ticket items that might not pay back all of their cost unless they are done to correct a deficiency in the property (i.e. adding a first floor lavatory in certain markets)."
