I am eager to serve you. Here are some of the things I can do for you:

Find Your Next Home

You need someone who knows Maui Real Estate inside and out! I can work with you to find the right home at the right price for you, including all the neighborhood amenities that matter – not to mention the essential criteria you have for your ideal home

Sell a Home

When it's time to move, you need someone who will advertise your home, show to prospective buyers, negotiate the purchase contract, arrange financing, oversee the inspections, handle all necessary paperwork and supervise the closing. I can take care of everything you need, from start to close.

Consult on Home Selling Tactics

Oftentimes buyers don't visualize living in your home the way you do. I can make your home attractive to its ideal audience – which can help you get top dollar. Things like staging the home, making repairs or minor improvements, or even simply painting the walls can be the difference between a home resting on the market and one that's sold fast.

She sold my grandmother's home in record time and was so great at explaining all the details of the transaction. We would have been completely lost with all the things that occur on a transaction. But she did such a great job.

Maria was very helpful through out the selling process. She kept me on track from listing to closing…done in about five weeks. Not only was Maria knowledgable and quick in responding to contract matters, she provided a hand in being sure final walk thru was clean…above and beyond what I expected. Thank you, Maria

I highly recommend Maria Sims. She represented our interests in purchasing a home and we couldn't have done it without her! She was always available to answer questions throughout the process and a real pleasure to work with. I've already started recommending family and friends to Maria and will continue to do so! She's the best!
