Best way to fund 15k (pounds) lease extension?

[Liveinthewoods80]

My pound sign key isn't working! Apologies.

I have about 100 GBP in the bank and it would be cheaper to fund my flat lease extension with cash so I pay no interest. (The lease is at 81 years and the extension can't wait any longer).

However, I'm also thinking of buying a second home in a cheap area up north for between 60 to 90k, in cash, and I'm wondering if I should in fact take out a loan instead for the lease extension, as that money will come in handy if I do buy a second home. I am doubtful whether a bank would give me a second mortgage, or whether I would want one.

Another option - though just a daydream at the moment! - is possibly buying a motorhome instead of a second property so I'm not tied to a specific location.

If I don't buy a home/van I will just put the money in an investment fund.

Therefore, in my position, how would you fund the lease extension? Thanks for reading

A remortgage would be the cheapest. Why would you qualify for a loan but not a new mortgage? I'd prioritise extending your lease before any second home, so if you can't extend your existing mortgage or remortgage and have cash, spend it on that.

The lease is at 81 years and the extension can't wait any longer.
This. Use the cash because, amongst other things, it will make the procedure quicker. Why would you jeopardise your main residence for the sake of a holiday/second home?
You can buy the holiday home another day.

Thanks folks, you are quite right to say i should prioritise my lease extension.

Maofteens - I've only recently signed up for a new fixed deal for my existing mortgage on my flat so I have missed the boat till 2023.

If anyone has been in same position with a new mortgage/ remortgage and needed extra cash shortly after, and managed to get round it, please let me know!
Thanks
