.,. then Baltimore gas and electric showed up and said their gas leak detector detected small amount of gas leaking.. it was coming from a cracked head on the furnace.. so it was old and need of replacement.. so we decided to replace it completely  however I need to mention I have brought my mother in law on board to do the book keeping duties and she is on site 2 days a week to let the exterminator in and do paperwork.. she was bombarded by this tenant who was threatening to call the police due to no ac and without consulting me she hired someone who was willing to install a unit in 2 days time instead of a week and instead of spending $3,500 for a new unit she spend $7,000.. this is a huge problem for me as I have a policy of no work or repairs done over $500 without my consent.. so he got a new $7,000 unit.. and I have taken the checkbook from my mother in law..

By law, rules have to be in a separate document, but can be changed from time to time without the tenant's consent.

Tenant shall neither sublease nor assign this Lease without the prior written consent of the Lessor, which shall not be unreasonably withheld.

Just curious, was there a clause in your lease agreeing that the tenant could make alterations and repairs without your consent or was this an implied agreement?

You could probably arrange for the property to be moved with consent of the former owner, but bear in mind any undertaking you do towards the property opens you up to liability.

If the owner used the deposit for a valid reason, with the tenant's consent, that is their prerogative.

Also, the landlord can not legally rent any portion of the area you occupy without your consent or until he regains legal possession of the unit.
