If I'm moving back to my home country, do I still need to provide an EIN or TIN to a property management company for my US rental properties?

If you already have a US Social Security number and US bank accounts, that generally covers what a property manager needs, and moving abroad does not change it. A separate EIN is usually not required just because you leave the country. Owning and managing US rentals from abroad is completely allowed. The property stays yours no matter where you live, and a management company can run the day-to-day from a distance. The tax side is where the real questions live: - Rent from a US property is US-source income, so you typically still file a US return on it using your existing taxpayer number. - Becoming a nonresident can trigger additional withholding and reporting rules for you and for whoever manages the property. We are not tax advisors, and cross-border situations get complicated fast. Before you move, sit down with a tax professional who handles expat and nonresident filings to confirm exactly what you need to provide and file. That one conversation can save you from withholding surprises and penalties later.
