Should I renew lease with current tenant who is late on rent

[Hongqing Yao]

Hi Experts, Veterans,

I am a new landlord in Brookline/Boston area (generally Class A area with subway access). I rented my 3B1B condo out at the beginning of the year. The tenant is a family with a few kids. He has some financial difficulties in the past few years but he had good reference in the past 5-6 years. So I decided to give it a try. However, he was late on rent twice recently. The first time was because of bank holding issues for over 30 days. The second time/ current month is still not paid (15 days late). His lease is coming to end at 8/31. 

Since I am a newbie, I really do not know how would you evaluate the situation. Should I evict them? Or just simply not renew lease with them. I am thinking just not to renew lease would be the best option because of the lengthy process of eviction here in MA. I would definitely like to hear some advices from you.

Thanks!
