Referral-based business in real estate involves the practice of generating new clients through referrals from existing clients, business partners, or other contacts in the industry. Real estate agents and brokers often rely on referrals as a key source of new business, as satisfied clients and industry contacts can provide valuable endorsements and introductions to potential buyers and sellers. Referral-based business can be highly effective in the competitive real estate market, as it can help agents and brokers establish a strong reputation and build long-term relationships with clients. To succeed in referral-based real estate, agents must provide exceptional service to clients, maintain a strong network of industry contacts, and actively cultivate their reputation and brand.
