Buyers message several brokers at once. The one who replies first usually gets the viewing. Everyone else finds out later that the unit is taken.
Inquiries land across Messenger, Viber, text, your listing sites, and whatever ads you're running. They sit in different inboxes owned by different people. Some get answered in minutes. Some get answered in two days. Some never get answered at all, and nobody notices because there's no list to check against.
Then the ones that do get answered live in an agent's phone. When that agent goes quiet or leaves, the relationship goes with them.
The fix isn't more leads. It's making sure every inquiry gets a reply immediately and lands somewhere the brokerage can see.
A listing inquiry page that asks the right questions and works properly on a phone, which is where your buyers are.
The buyer gets a real reply immediately, at 9pm or on a Sunday, before they message the next broker.
The lead reaches whoever should handle it, with the buyer's answers attached so the first call isn't a cold one.
Every inquiry lands in a CRM you control, so the record stays with the business when an agent moves on.
