What is the deal exactly, with One Percent Realty?

At One Percent Realty, we offer full real estate service while helping sellers reduce the amount they pay in commission fees. In terms of service, marketing, and exposure, we are comparable to traditional real estate brokerages. Your property is listed on MLS®, REALTOR.ca, and other major real estate websites. We provide professional marketing, signage (where permitted), showings, open houses, negotiation services, contract management, and guidance from listing to possession day. The difference is simple: you receive full professional service without paying unnecessarily high commissions.

For residential properties priced at $500,000 and under, we charge a flat fee of $5,000 plus GST. For residential properties over $500,000, we charge 1% of the sale price plus GST. The seller decides what they wish to offer the buyer’s agent, starting with an equal commission of 1%. For commercial properties, farms, or development opportunities, please contact us directly for a customized consultation.

Q.
Are your listings on MLS® and realtor.ca?

Yes. Your property receives full MLS® exposure and appears on REALTOR.ca just like listings from traditional brokerages.
