Selling two family, capital gains advice and multiple properties

[Michelle Costello]

I am selling my two family home in Boston, MA. I will make about 200k off this sale. I lived in the home for 5 years and rented the second half out. Am I entitled to exemption on the whole property? If not, can I use my profit to purchase two single family homes instead of one large two family? One single family will be my primary residence... the other will be rented out. Please help I’m so confused!
