Thank you all for your time in responding. I am working overtime at the moment but I hope to reply in more detail soon.
Company X are still in the picture and contact my father regularly. They have their own in-house Finance and Mortgage Broker team so my father does everything through them – ultimately losing all control as he has to sit back and wait for the finance team to come up with a solution.
It seemed like a good idea at the time to have a one-stop shop but now I can see how much control they have throughout the entire process from buying and financing through to rental guarantee.
