If you are planning to eventually move into a new home a large scale home renovation does not necessarily make sense. There are however several up grades that can be accomplished to make your stay more gratifying. First, determine how long you plan on living in your current home. Then decide what improvements are necessary for your contentment.
There is a difference between repairs and renovations. No matter how long you plan on staying in your home some things will need repaired. But a home renovation improves your home and helps to make your stay more enjoyable and sometimes your home more valuable.
