Good luck on this amazing adventure.
Agree with @Philip3527 …pick your best feature or features and craft your story/photos around the “hook”
If your story is “mid-century”; then lean into it, everything should be “mid-century”…not just the age of the house /or the living room furniture.
Photos: make a shot list, and stick to it
Feature only the best versions of the pix:
1-2 killer overview pix and 1-2 detail shots per room, all else goes into additional photos….ie. Your extensive game collection…
No …price tags, nail hooks, cord wires, etc..
Great benefit to have fresh eyes.. partner/trusted friend… double checking the pix on all devices: phone, iPad, desktop…and then tweak
