2. A Landlord should notify you 90 days in advance of a rent increase. Last I looked, not required in MA.
3. Market rates usually help in rental markets - OVER THE LONG TERM. Rent control can cause lack of upkeep - and may or may not diversify the community.
There was once Rent Control and there has been talk of reinstituting some form in the future as rents have skyrocketed, but nothing yet.
If an apartment is already at market value then the likelihood of a large increase in the future is minimal.
What we're seeing right now is an adjustment for relatively low rents the previous 10 years. That will eventually top off as well once demand decreases.
This has been typical as of late, since the rental market has gained so much steam.
I have seen number up to 20% higher over 1 year.
