That answer will be different from neighborhood to neighborhood. In Mission Hill you might get a studio for just under $1,000 and a 2 bed for $1,600. In Back Bay you might get a studio for $1,600 and a 2 bed for $2,500. 3 bed units are rare but you might get one in South End for $3,500. I use the word "might" on purpose - there will not be many at these prices and the rest will rent for higher. On average, rents in Boston have increased by over 10% compared to last year.
