Which area of the Third Ring Road in Beijing is the cheapest?

The cheapest one should belong to the South Third Ring Road, but now the subway on the extension line of the Third Ring Road is connected, so the price has also increased a lot. You can consider some old communities. Although the management of the community is not perfect, the property fees and parking fees are relatively small. You can see Jiayuan by Caoqiao, Xiluo Garden by Muxiyuan Bridge, Songyu Xili and Huawei Xili by Warwick Bridge.
