My twin sister and I recently inherited a shop with a 2 bed apartment above. The shop is currently being let for £590 month. However, the tenant in the flat above moved out last week but they were paying £550 month. The property is freehold and valued at £210,000. My sister wishes to sell the property but I’m wondering whether it could make a good investment. Should I buy her out with savings I have for £102,500. Are there any property investment gurus out there with any advice?
