First home Loan amount

[Jesus Gonzalez]

Hey everyone! I'm super new to this world but I'm super locked in. Im 34 years old and have my mind set on real estate investing. I'm about to move out of my current place and into my moms house after so many years of being on my own. The goal is to save from 50k-75k in about 2 years. I'm looking to get a 3 unit multi family home in or close to Boston MA. 
my question is is it realistic with a income of 75k-100k to be able to get a 800k loan? With including the units as potential rental income as well? I want to know what to expect as far as loan amount after saving. Would this be something realistic? Please and Thankyou!
