What does "unlimited leads" mean in Premier Agent?
It means there is no cap and no per-lead charge. It does not mean a promised quantity.
Unlimited describes the absence of a limit, not a volume we undertake to deliver. How many leads arrive depends on demand in the area you choose — a subscription in a busy city and one in a quiet region cost the same and will not produce the same number of enquiries.
If you want an estimate of demand in a specific market before subscribing, Housing Market Insights is where to look: it reports what property shoppers are actually searching for, by country, region and city.
