@Chase Prater There are very very few deals that sit on the MLS in Chattanooga. Most are gone before they hit the MLS. Typically, not always but typically, you are only seeing the ones that no one wants either because the price is too high for the condition or the area is rough. Chattanooga has attracted investors from Cali, NY, Hedge Funds, as well as having a healthy amount of us locals who are watching the MLS and buying off-market too.
I'm 99.9% sure I know which duplex you are looking at on the MLS and I can tell you that the area brings low-quality tenants. For that, I don't play in that playground but to each his own. I will say, for those who do play there, they are looking for much much better than 1% rule to cover the additional headaches that come with the high crime, poor tenant quality areas. The numbers you posted give you lower than 1%. I'd keep looking.
Get on the lists for the wholesalers and start working with a good property management company to help you vet the areas. They are going to be the ones handling most of that tenant headache. You don't want to buy and then figure out that you can't find a PM who will work that area for normal rates.
