@Koren Shoshan It doesn't seem like a bad deal. Especially not for a primary residence. The taxes will be much lower than an investment property, which will be helpful.
It really depends what market you're in, the immediate area and the condition of the home.
Cap rates and values different significantly from Charleston to Columbia to Greenville, so he ROI will be different in each market. It also looks like at least $995 is the market rent for the units in good condition, so you should be able to bump the under performing units up a bit over time.
In the Charleston market, it's almost impossible to find anything at the 1% rule anymore, so not likely you can get the seller down that far. We're usually closer to a .75 or .80 purchase price to rent ratio (ex. $750/$800 in rents, purchase price of 100k). I would probably try to start in the 420/425k area, but if all the mechanicals are good and I can easily push rents to 1k+ without much work, 440k could be a good buy. Again, I don't know enough to tell you for sure, but these are generalities based on my market.
