Buying a house might not be a very good sob story in their eyes. You’re basically telling them you want to move your assets from Monzo shares and into Real Estate.
A better reason would be that your mortgage is being foreclosed and you will be homeless if you don’t come up with the money, or your loved one died and you need to pay for their funeral, or something… anything but that you want to sell Monzo to buy different assets!
There has definitely been a tightening of their enterpretation of the rules in the last few years. I think it’s because it involves Crowdcube’s legal team and Monzo’s Board and none of them are getting paid extra for it, they are doing a favour by taking exception to your case. Neither of them are interested in going the extra mile for people who they probably think are bending the rules. Especially if you’ve already called in this favour from them before for trivial reasons.
Hope my tone doesn’t imply judgement. I think anyone should be able to sell their shares to whoever they want and whenever they want, but I don’t make the rules
