Frequently Asked Questions

What is the most important real estate term for first-time buyers to know? Understanding "contingency" is critical — it determines what conditions must be met (financing, inspection, appraisal) before a purchase becomes final and protects buyers from losing their earnest money.

What's the difference between pre-qualification and pre-approval? Pre-qualification is an informal estimate based on self-reported information, while pre-approval involves a lender verifying your financials and issuing a conditional loan commitment — making it a stronger signal to sellers.

What does "as-is" mean in a real estate listing? It means the seller will not make repairs or improvements before closing, though buyers typically still have the right to inspect the property and negotiate or withdraw based on findings.
