Double sales — if the contract is not registered in the regpalat, then two, three, or even several dozen times can sell the apartment.
Expensible apartments — the apartment must be rented out to the buyer on the time specified in the contract. However, many developers prefer to protect themselves by the vague wording of the end date, indicating the quarter of a particular year or all year. However, even if the date is determined, the developer can send a request to the buyer about a change in the contract 2 months before its end, at least this is supposed to be according to the law. If this was not done and the deadlines have passed, then for each day of delay the developer must pay the Buyer Penny in the amount of 1/300 of the rate of the Central Bank of the Russian Federation from the price of the contract.
