Effects of industrial park going in next to 9 acres with 1 duplex

[Joshua Strong]

Hello BiggerPockets!

I am looking at house hacking in a duplex that sits on 9 acres. The property will cashflow, its no home run, but it will produce income with the future chance of building more units on site! The kicker is there is an industrial park going in within the next 5 years that butts up to the whole 9 acres. Will this have a negative or positive effect on multi family properties? No idea if it will be manufacturing, distribution, or other. 

Thank you for your help BiggerPockets Nation!
