just can?t quite get my head round the maths here and who owes what. I?ll explain. About 4 years ago, I bought a flat with a friend. The cost was £148,000. We put down a 5% deposit with the bank, meaning that the mortgage itself was for £140,600. Fine. He now ?wants out? and the girlfriend wants to buy his share and move in with me. I have had the flat valued and it has gone up to an estimated £154,000 so that?s a £6k increase. I know a final sum is heavily open to negotiation because, for one, if we were to "just sell it," it may not ever get its value the estate agent say its worth, but I cant figure out how to break down how we reach a fair way of working this... So, if the girlfriend now does a transfer of equity and he *** off, what is he owed, exactly? He says he is owed his share of what he owns of the assets and he also keeps going on about the deposit, plus 50% of the increase? Is this true? What about the deposit? What would we need to pay him to get him out? I should also take into account that this is a leasehold property and there are currently around £3000 of communal works fees being paid off which won?t expire for ages (they?re being paid on a monthly basis). Therefore, around £1500 would need to be deducted from his claim. Hope someone can help!!
