Tim unless your current lease allows for changes to it any time in the leases term then your new LL has to abide by it and at this point the new owner has only told you they want more money come July first , the new owner has no told you to move out and the new oner trying to tell you its a 60 day notice will look like a giant fool in court if they try to hold you to a 60 day notice when your valid lease says 30. SO do plan for finding another place to move to and make sure you give proper written notice on real paper sent say via confirmed mail delivery by getting it into the mail early enough so the new landlord gets it by may 29Th or 30 th that tells the new LL you will be vacated by June 30 , make sure you pay your June rent and also to get enough stuff out say into self storage or a friends garage so you can clean every thing , take pics of how nice and clean it is and plan on treating your move out as if your going to have to sue the new landlord for your damage deposit money and so you are clear your new landlord cannot charge you for damages done to the unit when they didn't own it they can only charge for physical damage ONLY during the time they owned it So that ugly stain on the kitchen counter that's been there for the last year they cant charge you for but say your brother comes over tomorrow and is careless and sets his smoke on the edge of the counter while washing his hands and his smoke leaves a burn that is damage the new LL can charge you for but not one thing that happened before they bought it and take enough pics so you can prove what the homes final condition is .
