Hello BP People, 

I have a tenant that recently requested to renew her 12 month lease upon expiration, but she would like to add (2) new roommates to replace the existing tenants. The previous tenants have paid a single lump sum security deposit for the SFH. What is the best way to proceed, specifically on how to handle the security deposit? I am located in WA and the security deposit is equal to one month's rent. Current game plan is to start a new lease, with new security deposit, and return the refundable portion of existing security deposit to all (3) current tenants. Any insight would be appreciated. Thanks
