Speaking about the shortcomings of the used apartments, first of all, you should pay attention to the very determination of the secondary real estate market: in such apartments, someone lived before its sale. Based on this, we can conclude that the probability of the implementation of other transactions, and in certain cases, and their whole series. Other prescribed people, for example, minor children or owners who are in places not so distant, may also be in such apartments. The apartment must be checked for legal cleanliness. Otherwise, there is a chance that you will not be the only owner, but in some cases the entire transaction for the sale or purchase of an apartment may be invalidated. So remember this if you are going to buy an apartment.
