Tools for finding off Market Deals

[Ignatius Okeke]

I'm looking to subscribe to a service that helps find off-market real estate deals, and am considering options like Invelo, PropStream, Deal Machine, Property Radar, and others. However, I'm unsure which of these platforms supports specific search criteria such as non-paying tenants, code violations, absentee owners, vacancies, tax liens, deceased properties, probate, and inheritance. I would appreciate your recommendations based on these criteria.
