Condo Due Diligence Checklist:
What to Review Before You Buy
Buying a condo is different from buying a house. You're not just buying a unit — you're buying into a shared financial entity with its own budget, reserves, insurance, rules, and potential liabilities. The due diligence process is where you uncover all of that.
Most buyers skip this step or don't know what to look for. That's how people end up with surprise special assessments, underfunded reserves, and maintenance obligations they didn't expect.
