Can I trust listing photos to judge natural light?
Usually no. Photos get shot at flattering times, lights are on, edits happen. Orientation and sun timing are less easy to fake.

FAQ
Quick answers for home buyers
Is south-facing always the best choice?
South-facing is strong for all-day light. Then reality shows up. Trees, nearby buildings, and your exact unit position can change the feel fast.
Does this work for apartments and condos?
Yes. Pick apartment or condo after lookup, then choose front, back, left, or right so the estimate matches your unit.
What does low confidence mean?
Map data was thin, so direction is an estimate. That is why the slider and satellite link are right there.
Can I compare homes side by side?
Yes. Add up to four addresses, compare them in one screen, then export a PDF and send it to your agent.
Why does my home feel darker in winter?
The sun sits lower and traces a shorter arc. North-facing rooms can go weeks without direct light.
Does natural light affect home value?
Buyers pay more for bright homes. Orientation shows up in pricing data.
Which direction is best for a home office?
North for steady light, east for mornings, avoid west for video calls.
How much does the sun angle actually change between seasons?
About 47 degrees. Light reaches the back of a room in summer, stops at the windowsill in winter.
