The availability page is the product; the homepage is packaging
Almost every visitor who matters arrives on a property or a bio, not the front door, and the site should be designed accordingly.
Traffic comes from an emailed flyer link, a portal listing, a search for a submarket, or a broker's own signature. The homepage is what a client sees when they are already considering you.
So the design budget should sit where the visits are. A property page needs the address and submarket, size and divisibility, availability date, clear photography, floor plans, a location map with context a local would recognize, the covering broker with a direct line, and a single clear next step.
Homepages for brokerages should be short and unembarrassing. Who you are, what you cover, current featured availabilities, the team, one way to make contact.
Design the property template first and let it set the type, spacing and photographic standard for everything else.
