## Overview

This is a PHP/MySQL real-estate marketplace with separate public, user, agent, and administrator areas. The principal workflow is browsing and filtering listings, opening property details, and contacting an agent; users can also save listings, while agents manage properties and inquiries and administrators oversee accounts and listings. Registration, login, email verification/OTP, profile management, and SMTP email support these workflows. The README documents capabilities beyond the sampled excerpts; links for those are shown at the feature level, not as claims about unsampled call wiring.

Main entry points: [`propertiesgrid.php`](https://github.com/dixitvaghela11/real-estate-management-system/blob/main/propertiesgrid.php) (Listing search), [`register.php`](https://github.com/dixitvaghela11/real-estate-management-system/blob/main/register.php) (Registration), [`index.php`](https://github.com/dixitvaghela11/real-estate-management-system/blob/main/index.php) (Property home), [`login.php`](https://github.com/dixitvaghela11/real-estate-management-system/blob/main/login.php) (Login)
