I only pull permits when doing major renovations that include adding rooms or major modifications.

I am not sure if I can implement anything from American contracts to Canadian as we have different laws, so i would have to make modifications to suit my jurisdiction.

@David Matthew yeah the old lease has not expired; it has continued MTM and will until non renewal by either party, So your modification by change of terms or an addendum works fine.

When I told them the tile issue necessitated moving the tenants to the second side so that the tile could be repaired.

Not every seller is realistic on price and if you anchor your offer now  its likely you'll be one of the first people they come back to if there is a price modification.

They will be using to making minor modifications to the property such as painting the unit, using storage spaces, and etc.

@Jeff Silver, if the seller goes through a loan modification then why would they need to sell to you?

For it to be considered as a bedroom some modification needs to be done.

But recently there were some plumbing problems reported by the new tenant that have necessitated a plumber.
