Propose an amendment to the lease to raise the late payment penalty to the extent allowed by the law in your state.  

I have since gotten this amended...Hope that helps.

I have been in a similar situation and I always counter that when "mom" moves out I would be happy to do an amendment to the lease to show that now only two adults are living in the home.Hope this helps!

[Seller Concessions] around here being any Seller contribution to closing costs or Buyer's fees, credits given to Buyer at closing for repairs, and so on.We do have to have it specified in the contract -- or have the Sellers and Buyers review and sign an amend/extend -- that the commission is to be paid on NET Sales Price as otherwise the Closing company will *assume* it's being paid on GROSS and calculate the checks as such.

Hi all - I'm in an area with HOA and one of the residents wants to amend the HOA documents to limit the number of homes which can be rented out.

My relationship with my tenant’s is spelled out in my lease- I certainly don’t make on the fly amendments to the lease and I don’t expect them to.

@Shiloh Lundahl, I should amend my post a bit.

If you don't want the stuff there then you can amend the lease and if they don't follow those terms then you can have them evicted.

If it's a set term lease (not month to month), it will just end on the last day of the lease if not renewed/extended with a new lease or amendment extending the lease term. 

if you want to keep all the same terms than the suggestion about amending the current lease and extending the lease is probably what I would do.
