I imagine a T-6 is just a Trailing 6 month table that shows our rents, expenses all fully tabulated and organized into a summary table, but having a hard time finding documentation online to support that. 

If I were you I would get a good flavor from the tenants how they interacted with the previous owner, essentially, how they paid, how did they make repair/maintenance requests, when/why did the communicate with the owner, etc...

.: Hi,Is there a way to download specific addresses for houses in a certain area online?

Everything you need to learn/know is available online for free.

Document all your efforts, including repair invoices and communications, to show you’re acting in good faith as a landlord.

I've found deals in local online groups on Facebook, simply asking people for what I want. 

It's a more involved discussion that requires one on one communication and no, joining a "community" does not prepare you.

.✅ Stronger Tenant Relationships – Being involved directly allows you to build rapport with your tenants, which can lead to better communication and longer leases.Cons of Self-Managing❌ Time-Consuming – Dealing with maintenance requests, late-night emergencies, and tenant disputes can quickly become a second job.❌ Legal Risks – Chicago has strict landlord-tenant laws.

How can I communicate with you?

Plus, it integrates seamlessly with accounting tools like QuickBooks, making bookkeeping much more straightforward.Whichever account you choose, look for one with no monthly fees, online banking, and features like automatic bill pay.
