Seller's have real estate agents that work just for them. Buyers deserve an exclusive broker on their side too.


Great Puffin Real Estate exclusively represents buyers. We are dedicated to providing 100% loyalty, confidentiality, and unbiased showing of all available homes whether listed or offered by owners. As an Exclusive Buyer's Agency, we are legally obligated and have the resources to provide full disclosure on prospective homes, property value analysis, and the tough negotiating necessary to help you find the right home at the best price and terms.

As Exclusive Buyer Brokers, we will give you the up to date information you need to make a well informed buying decision, from identifying properties that meet your specific needs, financing options, home inspections, insurance, all the way through closing. We work throughout the Greater Portland, Maine area. If your needs are outside the Portland area, please feel free to contact Great Puffin Real Estate for more information on how we may best assist you.

Exclusive Buyer Broker Agency?

Our business is dedicated to serve exclusively as Maine Homebuyer advocates. We do not list homes for sale and we never represent sellers. We are members of the local, state, and national Realtor® associations and as members of the National Association of Exclusive Buyer Agents, we firmly believe that home buyers should have the same full and equal representation rights as sellers in any real estate transaction without conflicts of interest.

We never require retainer fees and offer a no-obligation consultation meeting. It does not cost you anything to have a dedicated broker on your side as our fees are typically paid by the seller in accordance with their listing agreement. You deserve the services of a broker who works exclusively with you to represent your interests above the interests of anyone else in the transaction and provide full fiduciary duty - the highest standard of representation in contract law.
