Met DP a few years ago and we both owned our own houses. I fell pregnant so we decided to move in together. Luckily I managed to sell my house just before the property crash - lucky me. So I moved into DP's house and we quickly realsied that it was never going to work living there (new build house, open plan, big dog and baby = disaster). We tried to sell it but couldn't, nobody was interested as the recession was well underway by then. Anyway, we found a large house that was a reposession, a complete bargain, and managed to scrape the money together to buy it (with large interest only mortgage). Subsequently, we let DP'd house out to tenants. This was just over a year ago. Now I know we have 36 months to sell DP's house (now 24 months) before he is liable to capital gains tax. The thing is, he only paid £75k for it about 10 years ago, and it's now worth about £200k. The problem is I just don't think it will sell quickly, if at all. It's a gorgeous house, he has spent a lot of money on it, but it is tenanted and if we ask the tenants to move out and try and sell it, we will be seriously short of money without the rent coming in. My questions is, does anybody know how much (roughly) caputal gains tax would be if he doesnt manage to sell it within th specified time frame? I can't make head nor tail of the rules, and could do with somebody explaining it to me for my own sanity! Thanks
