Latest client remarks

My husband and I were first time home buyers, we had no idea where to start or what we needed to do. Mariles guided us through the process and went above and beyond to help us in every possible way. His positivity is contagious and he kept our hopes up when we felt a little discouraged. We are now proud home owners and we look forward to working with him again in the future. 

My thoughts: Home-buying is stressful when not in the right hands. Being able to put clients at ease while confidently moving the process forward, regardless of challenges is the ultimate success story in first-time homeowernship.


• Refinance coordinating

• Buyer negotiations and support

• Communication for parties in a transaction

• Arranging loans for broker and processing


My role with the company as a Mortgage Loan Originator, is to help especially our first-time homebuyers have an educated experience buying their first property. Refinancing is another area of expertise, with helping clients "borrow smart" in order to preserve homeowernship.
