I did a lot of research in finding what I thought was a clever tax accountancy firm that was on the ball for property investors. Unfortunately when I went along to this firm they didn't tell me that the director/accountant had sold the business to these guys.
My returns were measly and I changed accountants a couple if years ago and now enjoy the services of an accountant that has my best interests in mind.
I find most of the staff incompetent and the prices exorbitant for the service provided.

Approximate cost: $Don't waste your money!
