Sam Mangrio and Synergy Property Management is the ideal property management company. We have known Sam for 20 years and his reputation is impeccable. As rental property owners, living in New York, we have relied on Sam’s years of knowledge and expertise for rental success.

He readily provides solutions to problems, providing viable economic options and has saved us money through his professional maintenance service contacts resulting in fair pricing and discounts. His willingness to take the initiative and save us the hassle of any issues that arise have been a significant and much appreciated benefit of his professional service.

Sam’s process for identifying and screening rental applicants is outstanding. He found quality tenants who have taken care of our home, paid on time and completed the terms of their lease with no issues. During our most recent turnover Sam was able to see the previous tenants out, have the house painted and cleaned and moved new tenants in under a month.

Sam is very responsive to emails, texts or a call, and is consistently courteous and kind. We highly recommend Sam Mangrio and Synergy Property Management LLC for your rental services.

“We currently live overseas but own a rental property in Prince William County. We have used Synergy Properties to manage our rental from the start and wouldn’t trust anyone else with our investment. Sam and Kati are reliable, professional, and care for our property as they would their own, responding quickly with knowledge, support and the appropriate vendors. Synergy Properties has made it easy living abroad with a stateside investment property and we would recommend them to anyone, whether one lives a great distance from their property or right next door. 5/5 stars”.
