Renate, no property was indicated in your question.
If you are looking at a genuine rental property, there
will be a link to the landlord/property manager on
the ad page. You are better off clicking that link for
questions on status as you will be dealing with the
party who is renting the property.
Make sure you have double checked your ability to
buy as in today's market you can frequently buy
at a comparable cost.
Good luck to you
