Make a list of all potential renovations and additions. For example, you could add a porch or a sunroom to the home or replace old windows and kitchen cabinets. Look at your house as though you were a buyer, and try to find the things that would turn you off, like an old furnace or water heater.
Calculate the cost of each type of renovation. Some things you may be able to fix yourself, but others may require professional assistance. Your cost should reflect both parts and labor.
Choose the additions and renovations that are most urgent. Some renovations, such as granite counter tops, are merely cosmetic. Others, such as a 20-year old roof, are likely to be deal breakers. When someone looks into buying your home, they are also thinking about the expense to repair something that breaks.
Think of ways to decrease costs while still making the renovations you want. For example, you may be able to paint cabinets and change the handles rather than installing a new set of cabinets. Alternatively, you may also be able to create an outdoor patio from bricks rather than add a sunroom to the home.
