Address autocomplete
Google Places suggestions as the owner types, so typos and missing unit numbers don't break the lookup.

The Problem
Homeowners look up their value long before they call an agent. If your site can't answer that question, the curiosity turns into someone else's listing.
01 · Portal estimates
Owners get a portal estimate and leave without an agent.
Your own tool shows a value range from a licensed AVM provider.
02 · Slow forms
Your market analysis form promises a call in a day or two.
Owners see a range after leaving contact details, then book a CMA call.
03 · Messy addresses
Leads arrive with half an address and no property details.
Address autocomplete confirms the property before anything else.
04 · Forgotten owners
Nobody calls curious owners when they're finally ready.
Each lead reaches your CRM as a seller inquiry with an agent alert.
An owner in your farm area wonders what their house would sell for. They search, land on a portal estimate, and leave with a number and no agent. Your own site offers a "free market analysis" form that promises a call in a day or two. Few owners fill it in. Meanwhile, your seller ads pay for clicks that reach that same form. You can't tell which owners were curious, so nobody calls them when they're ready.
We start with the question owners already ask: what is my home worth? The tool asks for the address first, confirms the property, and collects contact details before it shows a value range from a licensed AVM provider. Each lead reaches your CRM as a seller inquiry, and your agent calls with a real CMA. These are seller leads real estate teams can act on: a name, a phone number, and the exact property.
Address first, then details
Autocomplete confirms the property, so every lead arrives with a clean, usable address.
Licensed valuation data
Estimates come from an AVM provider's API under your own data agreement, not scraped portal numbers.
CMA booking built in
Each lead can book a call for a full comparative market analysis with an agent.
Our Valuation Tool Process
You pick the data provider, approve the form and the wording under the estimate, and test the tool with your own address before any owner sees it.
We review your site, your seller ads, and your CRM setup. You get a recommendation on data providers for your market, the form steps, and a fixed price for the build.
What's Included
The build covers data, design, and the handoff: the provider connection, the form and result screens, a seller page, and alerts to your agents.
Compare Options
An IDX form suits agents who only need a request box, and a portal link costs nothing. Here is how each handles the lead once an owner asks for a value.
| Feature | DeveloperLookBest fit | IDX valuation form | Portal estimate link |
|---|---|---|---|
| What the owner sees | A value range right away | A promise of a call | The portal's estimate |
| Where the lead goes | Your CRM, tagged as seller | Wherever your IDX sends it | Nowhere you control |
| Valuation data | Your licensed AVM provider | Often none shown | The portal's own model |
| Design control | Built to match your brand | Provider's template | No control |
| Next step offered | Alert plus CMA booking link | Depends on your CRM setup | Nothing for you |
| Setup time | 2 to 6 weeks | Same day | A few minutes |
| Upfront cost | From $950, fixed scope | Included in your IDX plan | Free to link |
| Ongoing data cost | Paid to your provider | Usually none | Nothing to pay |

What Our Clients Say
Feedback from teams we have built websites and web tools for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
An estimator touches three things you care about: your data costs, your reputation with owners, and your listing pipeline. These habits protect all three.
Every result shows a range and says plainly that it isn't an appraisal. Owners trust an agent who's honest about the number more than one who oversells it.
You hold the AVM provider account and the API key, and we set lookup limits. Your costs stay visible, and nothing breaks if we part ways.
We test condos, new builds, rural routes, and unit numbers before launch. Those are the addresses where valuation tools fail quietly and leads get lost.
The tool opens the conversation, and your agent closes it with a real comparative market analysis. We build the handoff so no seller waits for that call.
The code, the pages, and every lead are yours from launch day. You can move hosts or agencies and keep the whole seller funnel.
You get a written scope and a fixed price before any work starts. Data provider fees are listed separately, so there are no surprises later.
Overview
DeveloperLook builds home valuation tools that turn anonymous visitors into real estate seller leads. We connect a licensed AVM data provider, add address autocomplete and a contact step, and send each lead to your CRM with a CMA booking link. Builds start at $950 and most go live in 2 to 6 weeks. You own the tool, and the data contract stays in your name.

Good fit
Listing agents short on seller leads
Your site gets visits from owners in your farm area. None of them fill in the contact form, so you can't tell who's thinking of selling.
Teams running seller ad campaigns
Your seller ads send clicks to a generic contact page. You need a home valuation landing page that gives owners a reason to share their address.
Agents replacing a portal estimate link
Your site links owners to a portal's estimate, and they don't come back. You want the estimate, and the lead, on your own site.
Brokerages with many agent sites
Your brokerage wants one valuation tool across 30 agent pages, with each lead routed to the right agent by area or by page.
Agencies building realtor funnels
Your agency builds seller funnels for realtors and needs the valuation piece built, connected to a data provider, and supported under your brand.
Not a fit
Running the ads too
You want us to run the seller ads as well as build the tool. Our Real Estate Lead Generation Services program covers the campaigns every month.
Formal appraisal needed
You need a formal appraisal or a price opinion for a lender. An automated estimate isn't an appraisal, so a licensed appraiser is the right call.
Simple form will do
Your budget is under $950 and a simple form will do for now. Your IDX provider's built-in valuation form is a cheaper start, and we'll say so.
Buyer payment calculator
You want buyers to see what a listing would cost each month. Mortgage Calculator Development for Websites is the page for that tool.

Custom home valuation tools start at $950 for a widget on your existing site with one data provider and CRM handoff. A full seller funnel with its own page and nurture is $2,250, and a brokerage hub for many agents starts at $4,400. Data provider fees are separate and paid to the provider.
Most valuation tools launch in 2 to 6 weeks. A widget on your current site takes about 2 weeks once the data account is open. Seller funnels with nurture take 3 to 4 weeks, and brokerage versions with routing take up to 6. Data provider approval can add a few days.
Agents capture real estate seller leads by answering the question owners already ask, then asking for contact details first. An owner curious enough to type their address is often weighing a sale. The tool confirms the property, collects the contact, shows the range, and offers a CMA call, which is where your agent takes over.
The calculator is the front end, and the AVM is the data model behind it. An instant home valuation widget sends the address to a provider's AVM, which estimates value from sales, property records, and local trends. ATTOM's AVM returns an estimate, a low to high range, and a confidence score, which we use to decide what to show.
We split the form into short steps: address, a quick property check, then name, email, and phone. The value range appears only after the contact step, and your page says so up front, so owners aren't surprised. Text messages go only to owners who tick the consent box.
The automations that work hand the lead to a person quickly. Each lead reaches your CRM as a seller inquiry, and the agent gets an alert. The owner gets an email with the range and a link to book a CMA. Owners who don't book get a short sequence and a monthly value update.
US tools usually run on a commercial AVM provider such as ATTOM or HouseCanary, which offer valuation APIs. Coverage and pricing vary by provider and market, so we compare them for your area first. We don't scrape portal estimates, since that breaks their terms of use and can stop working without warning.
Yes, and it tags them as sellers. For Follow Up Boss we post a Seller Inquiry event through its events endpoint, which starts your action plans and automations. Other CRMs connect by API or Zapier, and every lead carries the address, the estimate, and the page it came from.
Yes, you control what the result screen shows. We can show a range instead of one figure, hide results when the provider's confidence score is low, and offer a CMA instead. Owners with unusual homes then talk to an agent, which is what you wanted anyway.
You own the tool, the pages, and every lead from launch day. The data provider account is in your name, so the contract and costs stay under your control. Support runs 30, 60, or 90 days by plan, and after that we can make changes at an agreed hourly rate.
