Today, the average Boston roommate living with others will spend $1,321 per month on their share of the rent. But affordability is a big problem, even for renters who are saving money by sharing. The average roommate rent is inflated way above pre-pandemic levels, and has not dropped below $1,200 per month in over three years, as shown in the chart below.
SpareRoom's data also shows that demand in Boston - based on the number of enquirers in competition for each room available to rent on its platform - is up 53% year over year.
Matt Hutchinson, director of roommate site SpareRoom, comments: “These latest rent increases point to intensifying pressure on limited supply at the sharp end of the rental market, where sharing as a roommate is dramatically cheaper than renting a studio or one-bed apartment.
“Renters chasing financial savings can bring their living costs down significantly by sharing as a roommate but, with roommate supply so limited, that may not be the case for much longer. For those who have considered sharing their homes, there's perhaps no better time to find a roommate and boost your income while contributing to much-needed rental supply.”
