Sorry Slider, misread your intention as you were moving from one to another property not that the owner was changing.
Change of owner only necessitates the property manager/owner to notify OFT of change of ownership, no need for a second bond.
It's not the owner's problem that the tenant still has to wait for their bond money to be released from another property. If you're that tight, is renting an option?
No bond, no keys.
