Hi Brenda,
Thank you very much for the details, it helps us a lot!
First and foremost, I will recommend a few documentation chapters, which will explain most of the details on understanding the filters.
Before starting with the filters, make sure the correct post types are selected and the search is set up properly and is returning the properties as results. After that you can choose a theme to suit your needs the best.
First you should start with the frontend search settings glossary. Then move right on to the first chapter to understand the positioning and layout of the search settings.
Then, you can start creating the desired filters. The ones you may likely need are the taxonomy term and the custom field filters.
