I posted upthread about selling our house and the major improvements we made, but here are some other, less expensive things we did to show our house to it's best advantage:
1. We got a POD and emptied out as much as we could (about a third to half of our furniture, furnishings, knick knacks, etc.). I pared everything in kitchen down to just the essentials. All of the bulky, rarely used appliances, excess pots, pans, cookies sheets, Tupperware, etc. went into the POD. Our rooms looked huge and the kitchen looked to have a ton of storage space.
2. Cleaned out all the closets. We live in New England. I packed up all the winter coats, boots, etc. I also packed up all of the winter clothes and only kept what was necessary in the closets. I went through and purged out all of our clothes. This was really helpful because it created drawer space so I could put some of the clothes from the closets in drawers to create more space in the closets. I love shoes and handbags and have a lot of both. I kept out the essentials and packed the rest away.
3. We took down all of pictures from the walls, patched the holes and painted.
4. The house had all hardwood floors so we used the restore stuff on them to shine them up. One room needed to be refinished so we did that.
5. Replaced the heavy draperies with sheers. Brought a lot more light into the house.
6. Made sure the landscaping was trimmed. We did have very nice landscaping and flower gardens so we didn't have to do much there.
7. The biggest thing was a deep clean of the entire house. Everyone that came through kept saying they couldn't believe how clean it was. I didn't understand that because there's no way I would show my house without it being clean, but when we started looking at home I couldn't believe how many dirty homes we saw.
