Generally the closest comps to your specific property as well as condition and how 'updated' it may be. You'd be surprised at how 'dated' only a 10 yr old home is from a realtor perspective. Don't be shocked if they tell you that you should 'upgrade' this, that, or the other. Weigh the expense vs return on investment. Don't be afraid to have that conversation with the realtor.
We just went through this last year selling Dad's 40+ yr old house with few renovations in that time. We did some modifications (painted; removed wallpaper; some floor refinishing) but not others.
Interview several realtors as well. Ultimately they will probably all come in close to the same asking/selling price, but make sure you make a commitment with someone you are comfortable working with. Much, too, depends on if you want out quickly or for the highest dollar. All factors to consider.
