8. How to Choose the Right “Big” Agent for You
When selecting the best estate agent, ask:
Do they handle properties in my price bracket?
What is their recent performance in my specific postcode?
How many buyers do they already have registered for homes like mine?
Do they offer off-market opportunities?
Do they provide premium marketing or only standard packages?
The right choice depends on your price band, speed expectations and whether you’re buying, selling or investing.
