if you're going into another job, 2 options I would think about . .
renting the round out for £xxx.xx per month. No employing etc, just let them get on with it and you get a regular amount each month. Plus you still own it.
or
Sell it on a deposit/ monthly payment scheme.
I've done both in the past, although it was with people I knew who respected me and treated my round like their own.
Both ways offer extra opportunities as people who haven't got 30/40k in the bank might be interested.
Damn, if I didn't need an income I'd think of selling mine for that amount !! lol
