@Raquel L.
I just went through this with a PA tenant that abandoned a house. I sued her in NJ where she moved back to.
In our leases we state that any and all notices for repairs or lease issues must be in writing with reasonable proof of delivery to out addresses (no phone calls or texts). This way what they pulled (telling your Mom) doesn't get them out of the notice required.
The point of a lease is to hold each other accountable, it's a contract binding on both of you, you not to kick her out and her not to abandon. I would hold her accountable till it's re-rented, you have to mitigate the damages by trying to find new tenants asap, so get it advertised and be able to show proof that your advertising.
I would consider all of June till the end of the lease term owed till it's re-rented, which ever comes first and sue for that. Make them enforce the contract.
Write up a move out repair & security accounting asap and get that sent out certified. If their negligence to notify you of a repair caused more damage, I'd charge for that repair as well.
My tenant never showed in court, I was asked for proof of my claims right then and there to proceed with my case to get a judgment, now past the 60 day appeal time period I petitioned for wage garnishment. on their jobs in NJ. The judge I went before was ready to shoe me away, seemed to be a bleeding heart, but I had all my proof so he had to go ahead with my trial & judgment.
Make sure you have *all* your proof if you go to court.
I don't rent to family or anyone I know anymore, I've been down that road before, never again. It's all just business now.
