If your bath or kitchen hasn't been remodeled in 20-35 years, do it now! These 2 rooms are the most important rooms in a home. You will nearly always get a 100% return or more on your investment but do the remodeling now while you live there, so you too can enjoy it.
Nobody wants to see old, worn out bath tubs, rusted out shower doors, leaky faucets and commodes that run. Pretty ceramic tile throughout your kitchen & baths create a fresh & clean look that says "welcome home."
So don't invest in spas, pool tables, or things that only appeal to a "few." Invest in the rooms everybody loves to use, daily. You'll be glad you did
