I need an on-budget WordPress website designed for the purpose of showcasing property listings in real-time. The site will feature both residential and commercial properties, providing users with a seamless way to explore available listings. Each property listing should include key details such as property images, comprehensive descriptions, pricing, location information, and contact details for the seller. Additionally, the website must integrate an XML property list page sourced from a third-party company to ensure accurate and up-to-date information. The site should be visually appealing, user-friendly, and optimized for performance.
