Permission to let

That'll be your mortgagees.

Sounds like the permission they have in mind is a short-term temporary one, and possibly without hiking the interest rate. Proper letting mortgages charge a higher rate but impose much more liberal conditions, and it is this latter setup which it appears is what you would need.

You could just wing it. How are they to know when your first set of tenants (which presumably they want to approve) are replaced with another, unless something goes wrong, of course, and they trash the place?

Which reminds me. You also need your insurer's permission, and chances are they won't allow it, and so you'll need to switch to one which specialises in insuring let properties.

You may well be wrong, but I'm not sure. Do you have a copy of the terms of the agreement? It could be that they would also need to give consent should you wish to let, for example. The other potential snag is that if the first charge would be redeemed and the first mortgagee replaced by a new one, that the second charge holder would technically become a first charge holder due to their charge deed predating the other. The new main mortgage lender might not be keen on securing their loan as a second charge, and so the original second chargee would need to consent to remaining in second place, as it were.

You didn't say whether the place you were hoping to move into would be rented or whether you're expecting to buy again. In the latter case, you could perhaps persuade the second chargeholder to transfer their charge to your new property.

If leasehold you will likely require permission from the freeholder for which they can charge what they like for every tenancy. A common scam. Read the property deeds.

Natch, another common scam.

As Ronald suggests, try and get away with not telling either the loan companies or the freeholder.

That's not actually what I suggested at all. I meant that, having obtained the lender's approval for the first tenancy, to keep quiet about subsequent ones.

I expect it's pretty risky not to tell the lender, because you really should tell the insurer, and the insurer might grass you up.

I would not have the same scruples about the freeloader, though.

Sorry Ronald.

As its a leasehold flat, then the buildings insurance is likely to be a block insurance and such permission may not be needed but is likely to require the leaeholder's consent.
