Cornerstone charges the industry standard of 10% of monthly receipts to manage a single family home, condo, apartment etc. There are no additional fees, ever. For multi-unit properties, we can negotiate our fee. You pay nothing when your property is vacant. This means we actively fill properties with qualified tenants and follow up arrears quickly. Regarding maintenance, our tradespeople are skilled at what they do, which minimizes call-backs and increases tenant satisfaction. Any trade discounts obtained are passed onto you.
