app.propertylistingoffice.com is a login page for something called Property Listing Office. If you've been directed here to enter your email and password, you should know what you're getting into before you do.
A legitimate property management platform usually has a public website with details about the company, a support contact, and legal pages like a privacy policy and terms of use. This site has none of those. There's no way to tell who operates it, and no one to reach if something goes wrong. That matters because this page is asking for credentials that could open access to your property data or personal information.
The technical side looks fine: the connection is encrypted, and the site is not on any blacklists. But a locked front door doesn't help if you don't know who handed you the key.
Is app.propertylistingoffice.com a scam? Not proven, but it's also not established as legitimate. Until the operators add basic transparency, treat it with caution. If you haven't signed up for this service through a trusted source, don't enter your login details.
