I am also not a big fan of collage photos.

@Martin StreichPlease go to your profile page https://www.biggerpockets.com/users/msresolutions and click on your photo to update it.

You need photos that stand out and align with the AI-driven algorithm prioritizing listings in popular categories.The 5 Must-Have Photos for Airbnb ListingsI have tested hundreds of photos and analyzed which listings perform best.

Lots of investors simply want to go "bold" on all of their projects by using sharp color contrasts, busy tiles that catch your attention, and modern lighting that looks like it belongs in a hotel.

AirBNB is a platform.Personally I like a single, eye catching line.

I would also cut down on the photo count.

Having reasonable expectations, hiring a local professional (Realtor or PM), doing your research, and doing everything right (i.e. pro photos, professional design, good renovation, proper amenities and location, etc) are the keys to success in 2025.

Or can I get away with zero exterior photos? 

Personally I don't ask for pics unless there is an issue and she sends them to me automatically.IMHO if you have a good cleaner that you trust, asking for photos is probably superfluous. 

If not, negotiate to buy it, get future cash flow secured, & take the next couple months to do the updates in between guests then get updated photos.
