But he needs to be sure it is. Land doesn't just become registered by
itself, but will usually make it onto the register the first time it

not changed hands for ages will therefore probably not be registered.

Fourthly, if you are likely to want to raise extra funds, then yes,

Yes, "may" being the operative word. With some ("flexible") types of
account the right to re-borrow principal already paid off is automatic.
With some, I dare say getting approval for an additional advance can
be as involved as getting approved for a whole new loan from scratch.
