Is this lease invalid?
Virginia lease agreement. Tenants are listed as my husband & I. Husband signed it, but I never did due to concerns. Made numerous attempts to meet Landlord (LL) to discuss, but she never met w/ me (too busy). Lived here 1 month (paid rent on time), but due to non-responsive LL, we want to move. Will forfeit deposit = 1 mo rent. LL initially agreed to release us as long as I found a new tenant. Found 4 good applicants, but she thwarted deals by not returning their calls,etc. Again – non-responsive.
Clause in lease says “The Lease(L) will not be considered valid by the LL, until EVERY signing tenant (T) and co-signee listed at the beginning of this L has signed and returned his/her L copy. In the event that one or more T’s listed at the top of this L fails to sign and return their copy of the L, the other T’s will not be forced, by virtue of their returned signatures, to assume responsibility for the residence. Subsequently, in the event of such a circumstance, all listed perspective T’s forfeit possession of the residence.”

Does this clause make lease invalid or can we be held liable for year’s rent because we lived here for 1 month?

Guest Clause
I’m about to sign a lease in the state of Virginia for a rental unit within a rental complex. I will be the only person signing the lease for a 2 bedroom. One clause concerns me: ”No persons, other than those named as Resident herein or as Authorized Occupants in paragraph 1(h) of this Lease Agreement, may occupy the Premises on a regular basis. For the purposes of this Lease Agreement, occupancy by an unauthorized person for more than seven (7) calendar days consecutively, or fourteen (14) days in any calendar year, without prior written consent from Landlord, will constitute occupation of the Premises on a regular basis and therefore will constitute a violation of this paragraph.”

1(h) pertains to minors.

1 – Is this a reasonable clause?
2 – If so, is it possible the landlord will not be helpful in providing ”written consent” for guests?

I’m moving to a new state and I expect my family and my boyfriend to visit often. I think I understand the intent of the clause, but it still concerns me. Any guidance is appreciated.

Security Deposit
Hi, I am a landlord of a townhouse, and my tenant informed me that he needs to move out on May 16, 2006. His lease agreement is not up until August 1, 2006. Needless to say I do have a mortgage on this house and this will leave me in a financial bind, especially if I cannot find someone else to rent it. By law, do I have to return his security deposit to him since he is breaking his lease agreement? Thanks.
