Is this a good deal - Duplex under contract Need advice

[John Moore]

Hello, I am under contract on this and running numbers. Would appreciate another eye. This is a summary - $39k pick up - duplex - one unit has some remodeling already by owner. another unit is occupied below market rent. 

1,000 gross

owner pays water

tenants pay everything else

approx. 385 cash flow 

Thank you in advance
