<prompt> Human: We live in a pretty big house in Sweden. After visiting relatives in London my mother now wants to take out a mortgage on the house and buy an apartment in London. She wants to rent it out after learning how high the rent is in London. Shes convinced this would be a good investment and that she would make the money back.I dont know much about mortgages or Real estate but I just have a bad feeling about this. Is this a bad idea?  <response>: Disgregarding whether or not buying real estate far from where you live is a bad investment, this idea still seems risky. The mortgage should be put on the London apartment, not the family home. If the worst happens and the apartment turns out horribly, now you potentially lose both that apartment and your family home? If the mortgage is on the apartment it seems like it would be a lot easier to untangle the mistake.Not being an expert on both Swedish or British real estate law, so maybe there is a good reason to do it this way, but it certainly wouldnt be my first choice.
