Two Acres, a Full Basement, and a Full Disclosure Form

Conclusion: You cannot present a disclosure you know to be false. Disclose, document, and if necessary resign the listing.

Reasoning:

1. Colorado requires a seller's property disclosure for most residential resales. A seller may not knowingly misstate a material condition, and a broker may not participate in or facilitate a misrepresentation - a false disclosure form is exactly that.
2. Both facts are material: recurrent basement water intrusion and an abandoned buried oil tank affect value, insurability, and environmental liability.
3. Your duty runs to disclosure of adverse material facts you actually know. You now know them. Silence is not neutral.
4. Steps: put your advice in writing to the seller; explain that the contract gives the buyer a disclosure deadline and a termination right if the form is not delivered or is inaccurate; offer alternatives - amend the form, obtain a basement/waterproofing evaluation and a tank/soil assessment, or sell with a modified disclosure structure counsel approves.
5. If the seller still refuses to correct the form, decline to deliver it and consider terminating the listing. Selling with a written record beats selling with a fraud claim attached.

Conclusion: The 1972 construction date triggers the federal lead disclosure rule; the tank is a separate material fact with its own treatment.

Reasoning:

1. Pre-1978 housing requires the seller to: give the buyer the EPA pamphlet on lead in the home; disclose any known lead-based paint or lead hazards; provide any available reports; and give the buyer a 10-day opportunity to conduct a risk assessment or paint inspection (which the parties may extend or waive in writing).
2. The disclosure must be delivered before the buyer is obligated under the contract; a signature obtained at closing is too late.
3. A toddler in the household makes the lead issue more than routine - recommend the buyer use the inspection window rather than waive it.
4. The abandoned oil tank is not lead paint, but it is arguably a greater risk: leaking heating oil can migrate and create soil and groundwater liability that can outlast the ownership. Advise the seller to obtain a tank/soil evaluation and disclose the tank's location and status; advise the buyer to investigate before removing contingencies.
5. Environmental conditions are a classic spot where the broker's duty to disclose known adverse material facts and the seller's disclosure obligations reinforce each other.

Conclusion: Answer with facts, referrals, and no opinions; you do not represent the buyers.

Reasoning:

1. 'Is the water safe?' is a health question. You do not know, cannot know from the listing, and should not guess. Point the buyers to the well permit on record, to water-quality testing by a certified lab, and to the county health department. Advise the seller to make the well and septic records available.
2. Well and septic systems are outside the scope of your expertise; the inspection contingency exists so the buyers can bring in a qualified inspector. Some counties impose their own septic inspection requirements on transfer - tell the buyers to confirm with the county.
3. 'Can they stop the subdivision?' Land use is a county decision. Adjacent owners generally receive notice and may comment at the public hearing, but there is no individual veto. Refer the buyers to the county planning department for the application, the hearing date, and the approval criteria, and to their own attorney for legal advice.
4. Also flag honestly that the subdivision application is a market and use factor the buyers should weigh, and that Colorado water rights are governed by the prior-appropriation system - a well permit describes a limited right to use water, not a guaranteed supply.
5. Keep it factual and refer out. Guessing at either answer creates liability for you and for the seller.
