Yes the landlord can be sued for breaking the lease.
Sure can.
Yes, a landlord in Maryland can sue for future rent if the tenant breaks the lease agreement. However, the landlord has a duty to mitigate damages by making reasonable efforts to find a new tenant. If the landlord finds a new tenant, the tenant who broke the lease agreement will only be responsible for the rent until the new tenant moves in.
The answer is probably not, but you can have the landlord arrested, or at least file charges against the person. To break the lease, you will probably have to sue in court.
This depends on the terms of your lease. Normally breaking a lease for any reason is grounds for the landlord to keep your deposit. If there are valid grounds for breaking the lease and the landlord keeps your deposit you can sue him for the amount he kept.
Check your lease agreement. If it is not stated in your lease agreement that felons are not permitted, then you have not broken any part of the agreement and the landlord is in violation of your contract. Sue him for breach.
If a tenant abandons a property without notice he is in violation of the lease, and the landlord can sue and/or keep the security deposit. The tenant may also be responsible for the rent of the unit during any time the unit is unoccupied during the remainder of the time of the lease.
The landlord has an obligation to try to rent it. If she cannot, she can sue you for each month, through the end of the lease.
It depends. If the sub-tenant was there by right and the landlord allowed a sub-lease, then that's a situation where nothing has gone wrong. If the landlord is suing, it sounds instead like the tenant did not have the right to sublet and in that case they are responsible to complete the lease and the sub-tenant may not have had the right to be there.
It depends on your lease. If you don't have a lease, the rent can be raised at any time by any amount. If you do have a lease, check the lease. If their are limits raising the rent in the lease, then you can bring that to your landlord's attention. If they raise your rate more than what's in the lease, then you can sue them in order to get them to comply with the lease. If there are no limits identified in the lease, then the rent can be raised at any time by any amount.
Technically, if you are in a lease then you cannot break it or the landlord can keep your security deposit and last month's rent. He can even sue you for loss of revenue up to the time the apartment is rent it out or the lease has expired, whichever comes first. That is the technical rule. But now here's the compassion issue: if your wife has passed away and there is compelling reason to break the lease, I am sure you can work something out with your landlord in which he can cancel the lease for you. But the landlord is usually not obliged to do this.
Yes, but don't expect to get anything unless you have actually suffered some financial loss due to the breach.
