Frequently Asked Questions
Does the seller provide all due-diligence information?
No. Buyers must conduct their own investigations.
Does Property DNA replace due diligence?
No. A Property DNA report may be one useful research tool, but it does not replace inspections, disclosures, title review, appraisal, insurance, legal advice or other professional investigation.
Can my agent guarantee that the property has no problems?
No. The agent can help coordinate the process, identify questions and recommend appropriate resources, but no professional can guarantee every property condition.
When does due diligence end?
Important contractual investigations occur before closing, but responsible ownership continues afterward through maintenance, records and appropriate professional evaluations.
A buyer does not need to become an expert in every property system. The goal is to identify the right questions and involve qualified professionals before accepting the risk.
