DJ Alexander, based in Dundas Street, said the guide was intended to help the growing number of homeowners who, because of the housing slump, had become the reluctant proprietors of two properties and needed to rent one out to help pay for two mortgages.
These are couples who typically have bought a new house but failed to sell their original property and so have been forced to keep both.
Boss David Alexander said: "These clients are not able to take as detached a view of letting as a commercial landlord would.
"In fact, it would be fair to say that most of them would prefer not to be landlords in the first place, hence the reason for the guide."
