First time investment property in Hopkinton

[Paria Allan-Blitz]

Hi all! 
We are about to put an offer down for our first real estate investment property. We’ve plugged in the numbers and, to our novice eyes, the deal looks good. We’d met +500/month. 
I’m wondering if anyone more knowledgeable here is willing to go over the numbers with us and just provide any kind of assurance that this is a good place to put our savings. Alternately you might ask some valued questions we haven’t thought of or raise other concerns. Either way, if you have a couple of minutes to spare, we’d truly appreciate your help. 

(Couldn’t add all 30 but this screenshot might be enough for you to weigh in on). 

Thanks again in advance!
