Encouraging farmers to buy houses in cities may have an impact on the property market, and the specific effect depends on the following factors:

Policy measures: The government's policy measures will directly affect the degree and way of farmers buying houses in cities. The government may provide preferential policies, loan support or tax relief to encourage this behavior.

Market demand: the scale and demand of farmers buying houses in cities will affect the property market. If the demand is large, it may increase the house price; If the demand is moderate, it may drive economic growth.

Urban development: This policy will also affect urban development and population distribution. Farmers buying houses in cities can promote urbanization, but they also need corresponding infrastructure and social services.

Generally speaking, encouraging farmers to buy houses in cities can have a positive impact on the property market and urban development, but it is necessary to comprehensively consider various factors and formulate appropriate policies to balance market demand and urban planning. The specific implementation and effect of the policy will vary from region to region.
