About Us

Sincere Property Management is locally owned and operated out of Oklahoma City, proudly operating under the brokerage of Block One Real Estate. The majority owners are Grant and Alicia Rubin, a husband-and-wife duo who started Sincere after seeing a genuine need for a company that sincerely cares about all the people impacted by the rental market—owners and tenants alike.

At Sincere Property Management, relationships are a top priority. We not only strive to protect our owners’ investments, but we also look for ways to partner and increase profitability through real estate acquisition, comprehensive rental market analysis, a full database of reporting, and a team dedicated to the success of our company and our clients. We don’t take it lightly that owners entrust us with managing their properties, and we approach this responsibility with integrity, respect, and transparency.

We also deeply value our tenants. We want good tenants to stay with us and feel the difference of living in homes managed by Sincere. Good tenants not only protect our owners’ investments but also stabilize long-term profitability. We take pride in the tenants we place and follow a robust screening process to ensure we find people who will treat each property with care and respect.

Sincere Property Management is more than just lease management and rent collection. We are a full-service, all-encompassing rental management and investment solution. From marketing and tenant screening to investor connections, cost-effective maintenance, and eviction support, our services are designed to deliver the best results possible for owners and tenants alike.
