This house is in a very sought after neighborhood in South Charlotte near Southpark. It is being sold out of an estate. If you do the math, then your will see that the difference between what the listing price is and the current market sold price is $9/sq ft. Fixed up price per sq ft is $182; list price is $173 per sq. ft.- leaves one with $20,754 roughly to renovate.
From the photos, the house needs heavy cosmetic renovation and probably needs new kitchen appliances too. The answer to your question lies with 1) whether you are doing the renovating or hiring it out and 2) at what price the house will sell for 3) how much mechanical and structural work needs to be done.
You are right that the recent comps are mostly 2 story houses. I think that the tax value is a bit high for our current real estate market. If you do buy, then I would be interested in how you handle the renovation. Many people would take the roof off to create a 2 story with dormers. Cotswold and Myers Park are full such renovations. Not sure what you mean by 100% renovation?
