At the age of 81 I found myself divorced and because I ended up owning our home, I needed to pay my ex-husband a lump sum of money I didn’t have. Because of my low income I couldn’t qualify for a regular mortgage. Big Horizon was recommended by my lawyer. Sharron...

“I called Sharron while searching desperately for alternatives for my 84-year-old mother.  After two full pages of notes, I stopped the phone conversation to let her know that she was the single most competent communicator I had ever dealt with on the phone....

In 2008, our family realized that Mom and Dad were having trouble managing on their own. We looked into in-home caregivers but we didn’t know how we would pay for it. Mom and Dad had no income other than social security, so we didn’t have a lot of options. We had...

Sharron is so competent, easy to work with, she LISTENS, and actively works in the client's best interest. Through her efforts I was able to obtain a reverse mortgage on my home which literally changed my life options.

Karl, Kennebunkport

I’ve known Sharron for years and have always considered her a trusted source for honest, straightforward and clear guidance. A first-class professional with a great demeanor, she is capable of distilling a complex process into its essential elements.

I worked with Sharron when I bought my first home - a multi-family using an FHA loan, and she was incredibly patient, helpful, and knowledgeable. She also found lower rates than any of the banks or credit unions I had contacted, and the process was smooth throughout....

Adrienne, Rockland

The service Sharron provided could not have been better!  What could have been a very daunting process was eased by Sharron's clear communications about the timeline and the documents needed. Highly recommend.

I recently purchased a home using a reverse mortgage. Without Sharron's knowledge, attention to detail and focus on this project it would probably not have come to fruition! 

Amy, Harpswell

With 2020 being tough and the future uncertain, I gave Sharron a call.  She helped me secure a refinance loan that will reduce my monthly payments tremendously! The process was all email and phone during the pandemic which was so easy for me, Sharron did all the hard...

Heidi, Cape Neddick

I’m very happy in my decision to pursue a Reverse Mortgage.  Sharron made the process easy and straightforward. Each step was done very professionally. Thank you, Sharron, for allowing me to afford to remain in my home.

Margaret, Biddeford

This is the time to do the “year in review”….OR NOT … this has been a year that has been rehashed again and again……… commented on, trashed, exalted….but it’s been a year like no other. For me it has been intense. It started out with the mortgage industry on the brink...
