Choose a community.
1, from the traffic point of view, the main factors are going to work and school. From your description, it seems that you have an electric car, and the traffic distance between them is similar, so you can get rid of this consideration;
2. From the external environment and surrounding facilities, we need the convenience of life, but living at home is not a matter of years, but a matter of decades or even a lifetime. Therefore, in the case of meeting the basic convenience of life, the environment is more important, so choose the community;
3. From the point of view of the project, there is no doubt about this, and Community A has an absolute advantage. Although the elevator is not the best, it is much better than Fujita. I don't want to say more about this, I feel too deep. Then there is the height. The height difference of 10 cm is very big, which directly determines the comfort of living, which can be fully reflected after the ceiling. Too low a height can make people very depressed and cramped; The distance between buildings is too small, which is not only a problem of lighting and safety, but also a problem of community congestion. Because there is no floor area ratio and building density, from this perspective alone, it should be said that the density of B community is relatively large and noisy; Property management, this is very important, linked to the elevator, because the maintenance of the elevator is also done by property management. If there is a problem with property management and the elevator is not good, then the future will be very sad.
As for children, as an experienced person, I suggest that you let your parents take care of your children. Since the situation at school is the same, why not let parents take care of it? Making the old people close to their children can also alleviate their loneliness and loneliness. They are more experienced. Or suggest that you spend more money to let your child enter a closed primary school, which is responsible for the child. Because of the internal differences between residential areas A and B, this is also very important for children. You don't want children to associate with people like XXXX, do you? If the property management is not responsible, the safety of children playing in the community is another hidden danger.
To sum up, according to the information you provided, I suggest you buy a house in a residential area. Because the difference is too big.
If you can provide your city planning map and specific information of each community: floor area ratio, building density, greening rate, total construction area, schematic diagram of community planning, etc. It will be more convenient to help you analyze and solve.
But from your simple description, it is better to choose the community.
