The real estate sale contract is included in a special group of contracts according to the nature of object - real estate sale. It should be noted that not all types of real estate may be subject to the sales contract, concluding with estate sale brokers, or estate sales online by means of real estate auctions online. So, land and other natural resources which are public domain of the country, can not be the objects of purchase and sale. Isolated water bodies (closed ponds) small in size and non-flowing can be traded, artificial ponds that aren't connected with other water bodies can also be in short sale and be owned by individuals and legal entities. They will pay real estate tax on them.

The real estate sale contract can be bilateral, for compensation, and a real one. Bilateral contract is considered as an agreement where there are two parties, one of which is a seller, while the other is a vendee. Compensation contract is considered as a agreement which includes rights and obligations of the parties as for the fee: one party (seller) sends the other party (vendee) real estate for fee. The real contract is an agreement in which parties comply with their obligations by a direct contract. Thus, immediately after the signature of the sales contract one party (the vendee) conducts calculation with the other party (the seller), and the seller, in his turn, conveys all the rights to property, which is the subject of the contract, to the buyer.
