Competitive Pricing

As a broker, we compare
16 different banks and lenders to find you the best mortgage for your financial needs.

Five Star Customer Service

We are in the business of creating raving fans. We want you to love our service so much you rave about it to everyone! 

Team Approach

We are a twelve-person mortgage lending team versus an individual LO, and our team leader not only runs the team, but also manages the entire company. Having a team model allows us to offer better service, and more consistent communication with our clients.

We're Local

We are local, we want you to help your dream of becoming a part of our community!

21 Day Closings with No Financing Contingencies

We pre-approve our clients as opposed to pre-qualify them. We want our client and the seller to have confidence in their home purchase and be able to close sooner.

We work with local appraisers

We work with local appraisers who have a better understanding of local comps and therefor provide more accurate appraisals and get reports back to us quicker than average.


We provide true ‘Pre-approvals’ and will call the listing agent to help set your offer apart from the
competition. This strategy, accompanied with our local reputation, helps win in multiple-offer situations.

We call you with weekly updates

We have found that having fantastic communication with both sides of the transaction helps with getting us to closing quickly, efficiently, and most importantly, on time! 

7 Day a Week Service

Don't worry, we are here to help on the weekends too!
