Well, if Nashville is like Tucson... or any other similarly sized city, those houses are likely not in a great part of town. We have 203 houses and condos under $175k in Tucson right now. I wouldn't live in any of them for their location(s) alone. Suckers from out of state have been buying... and I am sure regret the decision when they have homeless, tweakers and other ne'er-do-well's sleeping in the back yard or stealing anything that isn't bolted down.
Zillow has been buying in my neighborhood, and they overpaid... plain and simple. The offers my neighbors received were too good to be true. I mean, $50k to $150k over the z-estimate. Everyone in Tucson is laughing at Zillow all the way to the bank. Prices are going to crash here and its going to be brutal.
Ahh, you see, I have an ex-wife and a child I share custody with. I'm in the place that I'm in. Others are probably similarly constrained geographically.
I do WFH -- someday, I may head away from my current place, but I'm not that flexible yet.
There are currently 71 homes for sale in Nashville, TN at or under $175K.
