Estepona is having its moment, which is exactly when to look at the alternatives.
If what you want is the renovated-old-town feeling at a price that has not already moved, look at Casares or Manilva, ten to twenty minutes west. Both are less finished and less convenient than Estepona, and both cost less per square metre than anything in its centre.
If the reason you are here is that Marbella felt too expensive, check the gap again before you commit. It has narrowed, and it is narrowing further every quarter.
And if you want more town and less coast road, Malaga is under an hour east. A real city with its own airport, museums and a working centre, at prices that surprise anyone who has only ever shopped the western Costa del Sol.
Estepona earns its reputation. The renovation is real, the old town is very good, and the second airport matters more than people expect. Just be sure you are buying the town and not the story about the town.
