Letting your home out as a filming location has one main benefit; you earn some money!
Most Producers will be interested in using your location several times (though that will depend on the size and style of the location, and the needs of the shoot), and you get the fee for each day they work there.
Maybe you’ve put a lot of work into styling your home and you’re proud of it, and seeing it in professional media would be a nice acknowledgement of that?
Of course, film production is a bit glamorous, and that can be fun too! 🤩
