Hey there! If this is an abandoned house you should add the "abandoned:" key (https://wiki.openstreetmap.org/wiki/Key:abandoned:*) to define that information. As well, you should look for a more specific tag than "building=house" if you know it, as typically that's used for rowhouses, and in this situation may be able to be defined better. (https://wiki.openstreetmap.org/wiki/Tag:building%3Dhouse). Otherwise, thank you for your contribution to OpenStreetMap! On the ground knowledge like a building being abandoned, or what store is at a location, are some of the most important things to gather on OSM. Don't hesitate to ask if you need any other information, I'm happy to help :)
