Lease Addendum for a multifamily in MA

[Julia Ho]

Hi Everyone,

Does anyone have any tips for what important thing to be included in your lease addendums for multifamily properties rental in MA? 

Also, another question is that I have a lease condition that say "Tenant is responsible for lawn/yard maintenance and snow removal" and I reduced rent in return. Should I put the original rent $X and put a note in lease addendum that $Y is reduced from rent so tenant only has to pay $X-$Y? Or should I just put the reduced rent in the lease? Does anyone run into situation when your tenant is away during/right after snow storms and do not do snow removal? What would you do in that case? I have already reduced rent equal to (if not slightly more than) what I would hire a snow removal company for the whole season.

Thanks a lot in advance!
