I've lived in my current flat for 4 years. Last month, my landlord offered to sell the place to me - he owns a large portfolio of properties and is looking to offload a bunch of them. I'm interested - I like the flat and could afford it. But I'm nervous about dealing directly with him as a seller (ie. instead of through an estate agent). I'll be getting a solicitor, of course, and having a survey done, but is there anything specifically I should take care about? Has anyone else done this and what can I learn from you?
