In the late 80s, early 90s a fantasy book came out that I only read the first part of before I lost it. The premise was intriguing and I have always wanted to return and discover what happened.
From what I remember, a guy buys a house and finds a portal to another world in one of the adjoining buildings. When he first goes through the portal he lands on a beach and discovers a shipwreck with gold coins. He gathers some up, sells them on Earth and prepares himself to explore this new world.
That's all I can recall. Please help me put this one to bed.
