Home improvements often cost a pretty penny. However, some of them are definitely worth the cost if they increase the value of your home, not to mention the appearance and your enjoyment when you see it. Giving the exterior of your home a new, fresh coat of paint is a valuable investment, especially for curb appeal. Determining how much it will cost is not that difficult, and can help you put a monetary value to such an upgrade. You may decide you want to paint it yourself, if the cost of a professional painter is higher than your budget allows, but you would be investing more of your own time.
