Do basis work on the home and yard. Trim trees, edge yard, keep all excess stuff picked up in the home and year, clean any spider webs from the door ways, paint trim, and stuff to help set your home seperately from the others in the neighborhood. The first impression is the lasting.
The the inside of clutter, box unneeded items and place them in the attic, garage, storage unit. Keep as little clutter on counters, TV stands, Floors etc. Have a Fresh sent, once you first enter the home and keep the same sent going through-out the home. NO LOOSE PETS, this kills more showings than anything. If a buyer is scared or has allergies to animals, well the deal is dead before it starts.
This will bring the buyers to contract for you and you should get your value. Besides all this, you can do some upgrades, however I find even though you have upgraded items like granet counters, hardwood floors, etc. You really only get a fraction of the cost added to the purchase price and appraisal. Let the new buyers install the things they want, because when you put in Cherry Cabinets, they will want light oak color.
