I'll have to put a vendor up before I trade the house after the seven day wait is over and see what happens.
what is your question?
I do all the time... I log with house owner account, place a deed and rent to my other main account.
House owner open the contract menu, change from 7 days to 30 days rent period, change rent amount to Zero,
Change the option to auto renew YES.. And than target the person to rent...
renter: accept the vendor and check the auto renew option to yes....
after you transfer the house to a new account, the vendors will stay there, the only thing that change is that after you transfer a house with vendors to a new owner, all vendors contract change to NO auto renew....
All you have to do as new owner, is change each vendor option to YES.... And Renter do the same thing
