Whether there is a subsidy for buying a house with a loan depends on who is receiving the subsidy. If it is a government subsidy, government policies in different regions are different. Governments that are more supportive of real estate will generally provide subsidies in terms of tax incentives. Or grant partial exemption on interest. But most governments will not provide housing subsidies. This kind of government subsidy can be inquired by asking the developer or the local housing authority.
The loan subsidies issued by the company depend on the company's welfare policy. Generally, companies will provide some subsidies to employees in order to retain talents. For this kind of policy, you need to check with the company to find out whether there are housing subsidies.
