The vacant house problem is becoming more serious across Japan, negatively impacting the living environment of local residents. In Wakayama Prefecture, the vacant house rate significantly exceeds the national average, making it a particularly severe issue. It's thought that many of these vacant houses are difficult to distribute through existing vacant house banks or real estate agents. This research focuses on the vacant house problem in Wakayama Prefecture and investigates the effectiveness of Models for Transfer or Donations within the Community aimed at resolving issues with inadequately managed vacant houses. To verify the model's effectiveness, we conducted social experiments with this Models for Transfer or Donations within the Community in Wakayama City and Hashimoto City. As a result, we were able to find buyers even for vacant houses that were significantly leaning or suffering from rain leaks and poor management. The findings of this research not only demonstrate new possibilities for community-rooted vacant house countermeasures but also contribute to policy recommendations aimed at solving the nationwide vacant house problem.
