New landlord controversies in New Jersey

[Yangyang Jin]

I have come to find it very controversial for investors who would like to buy under valued asset, renovate, and raise rent, on the other hand, when we acquire properties, usually there are tenants living in these units already. In New Jersey, Landlord does not just have the right to vacate the tenants to move out in 45 days, there need to be good causes. And price under market is not a cause. I am curious to learn how other investors in New Jersey handle this? 

On the other hand, though I would like to vacate current tenants to increase rent tremendously, I also came to learn some tenants have been living there for over 10 years, have family and young children, paying rent on time. You would want to help them somehow. Vacate them is not the best way to help people either. How do you view this?
