it shouldn't make any difference what the money is doing, as long as you have enough so your wife will not need 'recourse to public funds'.
yes its a bit of a gamble
if you have bank statements showing you've got £60k and your thinking of buying land for £45k then nows the time to apply while you have so much in the bank and showing on your bank statements,. remember you would need to explain any large deposits or withdrawals. with £60k showing thou i would take that risk.
your gambling £550-ish, even if your refused you have a right to appeal.
