Need opinions- crack in foundation slab

[Sue T.]

Hi,

I am in the process of purchasing a duplex in Raleigh, NC; however, after getting an inspection report, I have my concerns. There is a crack (relatively small) in the concrete slab, but the crack runs from the front to back of the slab and is visible through the tile floor of living room, dining room, etc. There is also evidence of termite infestation (mud tubes in foundation wall).

The rent is a little more than 1% of the purchase price; not great, but maybe OK for the Raleigh area. What would you do? Would you walk or spend more money to get an estimate of cost to repair and then decide or something else?

Thanks for any help you can provide.
