Remember how there are little details that give your age away? It's the same for your home. You can't see it, but buyers will.....so try changing out some of the little things before going whole hog with a full gut reno. Start with:
1. Update light fixtures
2. Replace cabinet knobs and pulls (hinges if needed)
3. Update window treatments - get rid of the drapes and put in nice, clean white plantation blinds.
4. Replace faucets and shower heads
5. PAINT - re-color old cabinets; paint the back wall and add glass doors!
