Hi @Yinglu Wang! My wife and I own a duplex in East Ridge. The tenants have been great! There are some great areas of East Ridge and some not so great. The south side of East Ridge toward the East is up and coming. It is expanding with new restaurants, businesses and soccer complex coming soon. The north end by the ridge/tunnels is nice. That is where our duplex is. In the middle of east ridge there are some flood areas to look out for. There's a lot of water around the area. A sub contractor I spoke with recently told me that some homes have issues with moisture from the ground. Such was the case with our duplex. There was never a vapor barrier put in place under the home or gutters along the roof. We didn't realize it would be a problem. Half of the sub-floor needed to be replaced about two years after we purchased it. When we purchased, the reputable inspector told us that everything was good under the house. So it must have deteriorated quickly. We put about 10,000 in floor replacement and renovations this year. Many of the homes in East Ridge are older so I would recommend making sure that the property has good drainage and a vapor barrier. We love Chattanooga! It is a great area to invest.
