Real Estate Property Value Estimator Development
Budget: $30 – $250 AUD
Project: Build a Free Property Value Estimation Tool (Integrated with PropTrack API)
Overview
I want to build a free online property value estimation tool for my real estate website — similar to this example:
https://go.pocketappraisal.io/pocketapp/jordanbain
The tool should allow users to:
Enter their property address using Google address autocomplete.
See a blurred-out property value that remains hidden until they complete the contact form.
Once the user fills in their contact details (name, email, phone, and interest type), the property value and full report become visible.
The system sends the agent (me) an email with the user’s details and property address.
After submission, the user can view or download the full report similar to the PropTrack-style example attached.
Functional Requirements
Address input integrated with Google Maps Places API for Australian addresses.
Blurred valuation display until the user completes all required fields.
Validation to ensure the form cannot be submitted until all fields and consent checkbox are completed.
Once the form is submitted:
The user sees the full property report and estimate.
The agent receives an email notification with user details and property information.
Option to store submissions in Google Sheets, Airtable, or send them to a CRM via webhook or Zapier.
Mobile and desktop responsive design.
Include “Powered by Beshay Realty” in the footer with my branding and colours.
PropTrack API Integration
Developers must integrate with PropTrack’s Valuation API.
