My question involves landlord-tenant law in the State of: Minnesota
We took over a friend's remaining lease ( for June 1-end of August) and was told by the landlords we would be able to sign a year lease once the remaining one ended. After only 17 days of moving in they told us we would need to move out by September. We have two small children and one on the way, had we not been told we could sign a year lease we would not have moved from our apartment that we had been living at for 2+ plus years. We now at the end of June found a new home we plan to move into come July 1 but the landlords of the current home are telling us we need to finish paying the remainder of the lease plus have no intent of returning our deposit if we move out prior to the lease ending. Are we responsible for the remainder of the lease or are the original tenants responsible and are they allowed to keep our deposit strictly for this reason?
The original leasers are fighting the fact that the lease is invalid due to the landlords simply drawing a line through their names and writing ours in side space on the paper and giving us a copy of that lease that still has there names, phone numbers, and Social Security Numbers. Does this make the lease invalid?
