In Ukraine, the right of individuals – citizens to housing is constitutionally enshrined, which can be realized both by purchasing such an object of civil relations in ownership and in use. As of today, the issues of providing housing for the citizens of Ukraine have become particularly acute due to the fact that many of them lost it due to the criminal war against our state. These issues have become especially relevant due to the declaration of our state as a social state, because under such conditions, Ukraine must help its citizens to acquire rights to this category of property. For some reason, as of today, the most common basis for acquiring housing rights is the contract itself, which remains unique means of regulating legal relations in European private law.
 The concept of housing in Ukraine is provided in a number of normative legal acts of various levels of legal force, among which, of course, the Civil Code of Ukraine and the Housing Code of Ukraine that occupy a special place. Affordable housing is built and those being built with state support, residential buildings (complexes) and apartments. State support for the construction of affordable housing consists in the payment by the state of 30 percent of the cost of construction (purchase) of affordable housing and/or the provision of a preferential mortgage housing loan.
 Contracts for the purchase of this category of housing are sales contracts, that is, they belong to the group of transactions on the transfer of property into ownership. At the same time, by their legal nature, these are consensual, paid, bilateral and fixed-term (usually up to 12 months). In the case of investing in objects of unfinished construction, under certain conditions, such contracts may have a risky nature. Also, it is worth noting separately about: the specific subject composition of these contracts, the obligation to comply with the requirements regarding their form and specifics of execution.
