Create a Facebook post graphic with dimensions of 1200x628px targeting first-time homebuyers. Use a vibrant color palette of green, red, yellow, blue, and white to create an inviting atmosphere. Feature a welcoming image of a cozy home in the background, ensuring it is high-resolution and well-lit. Overlay the text "Your Dream Home Awaits!" in bold, modern typography at the center, using a contrasting color such as white or yellow for readability. Include a prominent "Call Now" button in vibrant red at the bottom-right corner, rounded with white text to ensure it stands out against the background. Ensure the design is clean and professional, with ample white space to maintain clarity and focus on the message.
