Why It Matters

Three things online estimates get wrong about your home.

Recent comps on your street

Algorithms average county-wide data. The sale of the house two doors down moves your number more than a sale across town — and most automated tools don't weight it that way.

Your home's actual condition

Square footage and bed/bath count don't tell a buyer whether the roof was replaced last year or whether the kitchen still has its 2008 cabinets. We do.

What's selling right now

Markets shift faster than algorithms update. Inventory in Yorkville right now looks different than it did 90 days ago, and your number should reflect today's buyer demand — not a quarterly model refresh.

The Process

What happens after you send the form.

Within one business hour

Kealan or a member of the O'Neil Property Group team texts or calls to confirm the address and a couple of quick details — basement finish, recent upgrades, anything that changes the comp set.

Within 24 hours

You get a written valuation pulled from the actual sold comps within a mile of your home, marked up with how each comp compares to yours.

When you're ready

If the number works and you want to talk through a listing strategy, we'll book a 30-minute walkthrough at your house. If it doesn't, no follow-up campaign — we'll thank you for the time and stay out of your inbox.

What sellers say after working with us.

★★★★★

The process of selling our home with Ryan was as seamless as one could hope for. He was so professional and supportive throughout the entire process. I would highly recommend Ryan and the whole team at O'Neil Property Group.

What a great experience we had selling our home in Plano with O'Neil Property Group. They kept us informed every step of the way and that made it easy on us.

FAQ

The questions sellers usually ask first.

How accurate is the valuation?

Within 2–3% of what your home would actually sell for on the open market, in most cases. We base the number on the homes that just closed within a mile of yours, weighted for size, condition, updates, and lot — not a county-wide algorithm.

Is this an automated number like Zillow?

No. Every valuation request that comes through this page is reviewed personally by Kealan. Automated tools miss the things that actually move buyers — recent updates, condition, and the comp two doors down. We don't.

Will I get follow-up communication?

Yes — but only what's actually useful. After your valuation, Kealan or a team member will follow up to make sure it landed and answer any questions. You can also opt into monthly market updates for your area, and you can unsubscribe anytime.

What if my home isn't in Yorkville, Oswego, Montgomery, Plano, Sandwich, or Sugar Grove?

We cover the rest of Chicago's Western Suburbs too — Naperville, Aurora, North Aurora, Plainfield, Batavia, Geneva, St. Charles, and surrounding towns. Submit the form and we'll let you know if your home is in our wheelhouse.

Do I have to list with you?

No. The valuation is free with no obligation. Most sellers who get a real number end up working with us when they're ready — but that's their call, not a condition.

How long does it take to get my valuation back?

Most valuations are written and back to you within 24 hours. If your home has unusual features or limited recent comps in your immediate area, we may take an extra day to pull the right data — we'll let you know if that's the case.

What information do you need from me to get started?

Just your address, contact info, and any condition details you'd like factored in (recent updates, finished basement, roof age, etc.). Public-record data handles the basics. Your notes do the rest.

Do I need to schedule a walk-through?

No. The written valuation is based entirely on comps and any details you share by email or text. A walk-through is only helpful if you're seriously considering listing in the next 30–90 days — and even then it's optional.

What if my home needs work before I can sell?

You've got options. We'll give you a current-condition valuation plus an "after improvements" range so you can decide whether updates make sense. Or, if you'd rather skip the work entirely, we can bring a private cash offer to the table — sell as-is with no repairs, no showings, and no contingencies. We'll walk you through both paths so you can pick what fits.

Can I use this valuation for refinancing or tax appeals?

It's a strong reference point but not a formal appraisal — lenders and assessors require licensed appraisers for those processes. That said, our written valuation includes the comps and reasoning, which often helps support an appeal or refinance conversation.
