Yes, please reach out to the landlord directly in order to schedule an in-person viewing.
Most renters find traditional estate agents don't truthfully advertise properties, which result in over 80% of traditional viewings as a waste of time. As properties are listed by landlords themselves, listings are much more accurate and truthful. You can also always message a landlord directly with any questions or concerns regarding the property, including to schedule an in-person viewing.
As well, look out for property listings with the Verified Badge, which indicate that an independent third-party has visited, verified, and personally shot the property's media. Verification badges reduce the need for in-person viewings and work to put trust back into the community.
