Buying housing in St. Petersburg is a rather responsible task. The desire to purchase the option is quite clear, you should only take into account all the most important points. What means can the buyer have? Does the buyer have the opportunity to live after making a purchase not in purchased housing, but somewhere else? If not, then it is best for him to decide that I will buy an apartment in the secondary market, since secondary housing is almost always suitable for living at least in the most modest version. And difficulties with the postponing timing of the commissioning of housing in this case cannot be. The maximum delay in the Enforcement is a few days after the transaction in the usual case or a little more in the case of force majeure, for example, a serious illness of the seller, due to which he will not be able to free the apartment in a timely manner. But this, fortunately, rarely happens. Secondary housing has its own certainty in terms of the quality of the house and the comfort of housing. There is an opportunity to ask neighbors to find out what seasonal problems can be in this area and in this building. But it can also have its own history – prescribed and timely not issued members of the seller’s family or issued with legal violations. Can be pledged or under arrest. Such details must be found out in advance, before the seller and the buyer take on any obligations.
