Keystone Realty USA is a real estate brokerage based in Kings Park, New York. In its own description, the firm calls this its official page and says it guarantees to beat any deal offered by any broker in New York, a promise that comes from the company itself.
If that guarantee interests you, ask Keystone Realty USA exactly what it covers, whether it applies to commissions, services, or something else, and what conditions must be met, and get the terms in writing before signing. Ask which towns and neighborhoods its agents cover and whether they work with buyers, sellers, renters, or landlords. Sellers may want to understand which services are included in the listing. Buyers can ask about inspections and timelines.
