<human>: My partner (29M) and I (26F) have been living in the same rented house for over two years now. We've been good tenants, only had one incident with a storage heater (our mistake) which we're paying off each month to the letting agent. 

Yesterday, a friend of my mother's asked if we were interested in looking at their property. They are moving out and want to rent their home instead of selling it. It's in a lovely area, it's only £80 more a month but has a lot more going for it than our current home (more modern, extra bedroom, garage access, more space), and the landlord would be happy for us to pay our deposit in installments since if we move out, we'd have to pay off the money we owe for the new heater out of our deposit.

The problem is - I spoke to our letting agent today and they said they would probably charge £188 as an early release fee, and of course since our tenancy doesn't technically end until October, if they don't find a new tenant before then we would be liable to keep paying the rent.

On the one hand, I think there's a good chance they'd find a new tenant quickly - it's a nice little home and it's not very expensive, which is what we were attracted to. And, although we're not very well off, I do have enough room on my credit card to pay their early release fee, so although that would set back my attempts to pay my card off by a couple of months, in the long-term it wouldn't be crippling.

Is this a terrible idea? Should we just accept that it's risky to try and move now, or go for it on the basis that a house this nice, for such an affordable amount, isn't that common where we live and there's no guarantee we'd find something as nice by the actual end of our tenancy?

I don't want to make the wrong decision - when I spoke to the letting agent she said herself she didn't think it'd take long to find a new tenant in the current climate. Any advice?

Give me the gist of the text in a nutshell
<bot>: Opportunity for nicer rented home as come up, want to break tenancy early but involves risk of being liable for rent if new tenant isn't found. Is it worth going for anyway?
