A market analysis and consultation with an experienced REALTOR for your area would be the first step so you don't spend money you may not recover. A fresh coat of paint, remove all the clutter, remove excessive family items, and update the kitchen/baths usually are the most return for your efforts. Without knowledge of your individual position all answers are strictly generic.
We would be glad to assist you more personally and our agents specialize in Fort Worth.
