Zestimate guide
How to raise your Zestimate before you list
Buyers see your Zestimate the moment you list. Here is the pre-listing checklist to get it right before it anchors anyone.
The Zestimate is the first number a buyer sees next to your listing — and the one they quietly anchor every offer to. If it is running low when you go live, it frames the whole negotiation against you. The fix is to get it right before you list, not after.
The pre-listing checklist
- Claim your home on Zillow and correct every fact — square footage, beds, baths, lot size, year built. Wrong facts are the most common suppressor.
- Add your improvements: renovations, additions, a finished basement, plus high-quality photos that show true condition.
- Pull your own recent same-municipality comps; if they sit above your Zestimate, the model is likely leaning on the wrong sales.
- Identify and document any out-of-town comps dragging you down, and report them.
- Verify your tax history and prior sale price on Zillow, and check your Zestimate history for an unexplained dip.
What moves the number — and what does not
Quantifiable facts move it: square footage, bed/bath count, a recorded renovation, the comps it uses. Cosmetic-only changes (paint, landscaping) usually do not move the Zestimate on their own. Focus your pre-listing effort on the facts and the comp set. The full method is in the correction guide, and why a Zestimate runs low covers the diagnosis.

How long before listing should I start fixing my Zestimate?
Give it 4-8 weeks. Corrections to facts and comps can take days to several weeks to recalculate, so starting early ensures the better number is live when buyers first see your listing.
Will fixing my facts guarantee a higher Zestimate?
No guarantee, but correcting genuine errors removes the things suppressing it, which often raises the number. At minimum it gives you a documented case for buyers and agents.
Does listing my home change the Zestimate?
Often yes — once listed, the estimate tends to drift toward your asking price, which is another reason to set that price on real comps rather than the Zestimate.
