This seller email is not automatically unreasonable on the site access piece. Scheduled visits, reasonable notice, and avoiding disruption in an occupied community are pretty normal. Where I’d be careful is the part where they try to control your due diligence too tightly: - restricting property-specific third-party inquiries, - forcing all inquiries through them, - delaying direct zoning/code verification, - and limiting vendor outreach tied to the property. That can become a problem fast. During due diligence, you need sufficient freedom to independently verify zoning, code, utilities, vendors, licensing, taxes, title, and operational realities. Otherwise, you are underwriting blind. And that violates the whole idea of due diligence. How will you buy this and never lose it? You do not want to close based solely on seller-filtered information. My suggestion is to respond professionally, acknowledge the legitimate operational concerns, but clearly preserve your right to complete independent due diligence under the PSA. See the attached response email that you could use. First, this email keeps you sounding cooperative rather than combative. Second, it does not accept their framing that all diligence must run through them. Third, it creates a record that you are requesting reasonable access under the contract. What I would do next: 1. Re-read the PSA language on inspection rights, access, third-party contacts, confidentiality, and non-disturbance. 2. Send a response like the one above and make them either agree or specifically state what they are refusing. 3. If they keep restricting zoning/code/utility verification, treat that as a red flag and involve your attorney immediately. 4. Consider asking for an extension of diligence time if access to or documents are delayed. 5. Do not let your earnest money go hard until you have independent verification of the major risk items. My blunt read: if a seller wants to “manage” all the facts, there may be facts they do not want discovered. That does not always mean it is a bad deal, but it absolutely means you need to slow down and protect yourself. Cash flow first, verification first, and control your downside.
