There are software tools made specifically for staging (and de-staging!) real estate photos. I don't know if they're using off-the-shelf image models or not, but they have capabilities like restricting changes to specific regions of the image which aren't available in services like ChatGPT.

(De-staging is a particularly neat trick - if a property still has some of the current tenant's belongings in it, an AI model can remove those items to show what the room would look like empty.)
