Need advice on Buy&Hold duplex

[Leigh Jones]

Seeking advice.  There's a duplex for sale, but the seller is not motivated to sell below market value.  If we pay market value, we will still cash flow $300/door.   Both units have renters; one that's been there 3 years and one that been there 14 mo. 

is it still a "good deal" if we're paying market value?.  We'd cash flow but wouldnt have a big equity cushion.
