The quality of images that stock photography websites are looking for is very high - professional photographer quality, with meaningful and relatable content - with very strict criteria for acceptance. Even many pro photographers struggle to get a decent acceptance rate, plus you need to provide a model release for any people in the photos and a location release for every location. These are completed by the people in the photos and by the property owners, stating you have permission to sell photos of them/their property. No disrespect, but you have zero chance of getting some amateur quality images of property you don't have permission to be on though that process. Even if you do somehow manage that, you'll massively struggle to make any money, to the point that it's just not worth it. The returns are minuscule (a tiny fraction of the selling price) and you need to be selling seriously high volumes of images to get anything worthwhile back.
