Opportunity to Purchase

Colorado law grants home owners time to form a group and make an offer to buy the mobile home park, which is called their opportunity to purchase. This means that sellers have at least one, if not more, waiting periods they must honor after posting a notice of intent to sell.

Think of it this way: After a landlord posts a notice of intent to sell, two countdown clocks start running at the same time:

  • 90 days to wait to ask for home owners’ signatures on whether they want to accept or decline the opportunity to purchase the park
  • 120 days to wait for home owners to form a group and submit an offer, unless 50% declined the opportunity

If a landlord posts another notice of intent to sell because they took another triggering action, both countdowns start all over again.

90 Days After the Notice: Wait to Ask for Signatures

As a seller, you must wait for at least 90 calendar days after providing notice of your intent to sell the park to ask for home owners' intentions or signatures accepting or declining the opportunity to purchase the park.

After 90 days, sellers may request home owners’ signatures.  If sellers request signatures, they must do so using the division-approved forms, Home Owner Intent - Opportunity to Purchase Park, in English and Spanish.

Unless at least 50% of total home owners in the park return the forms and state that they are not interested in participating in an effort to buy the park, you must honor home owners’ 120-day opportunity to make an offer.

Step-by-Step Guide for the 120-Day Waiting Period

Breaking down the 120-day waiting period for park sales in Colorado, especially for mobile home parks, and detailing what constitutes good faith negotiations under the state statutes can help potential sellers navigate this period effectively. Here is a simplified step-by-step guide, with references to specific statutes that outline the rights and processes for the sale of a mobile home park.

Post Notices of Intent to Sell

As a seller, you must first issue a notice of intent to sell the mobile home park.  This notice is the starting point of the 120-day period.  It should be delivered to each home owner, the county and/or municipality and to the Division of Housing, informing them of your intention to sell the park. See section 38-12-217(1)(a), C.R.S.


Alongside the notice, you must provide comprehensive information on the terms of the sale.  This includes the legal description of the property, price, terms and conditions of the sale, any financial considerations, and other relevant details.  You may also request to keep the sale information confidential. This information helps home owners understand what’s at stake and whether they want to pursue a purchase.  See section 38-12-217(3), C.R.S.

Good Faith Negotiation Period Starts

Once home owners are informed, the 120-day period is also an opportunity for them to organize and prepare an offer, if they are interested in purchasing the park.  Good faith negotiation means that during this time, you, as the seller, engage earnestly with any proposals from the home owners.  This doesn’t necessarily mean you have to accept their offer, but you must consider it seriously and negotiate in an open and honest way.


Ensuring Good Faith

Good faith negotiations are marked by actions that demonstrate honesty, fair dealing, and an earnest intention to reach an agreement that is mutually acceptable.  As a seller, keeping the lines of communication open, responding timely and thoughtfully to inquiries and offers, and promptly providing all requested information are all part of negotiating in good faith.


No Unreasonable Refusal

If the home owners submit an offer to purchase the park, you cannot unreasonably refuse it.  Good faith negotiations require a willingness to arrive at terms acceptable to both parties, within reason. See section 38-12-217(5)(b)(l), C.R.S.

Engage in Transparent Communication

Throughout the negotiating process, maintain clear and transparent communication with the home owners.  Any counteroffers or negotiations should be clearly documented and shared with the home owners’ representatives to ensure transparency.

  • You may enter a conditional contract with an outside individual or business. For example, the conditional contract recognizes home owners' opportunity to purchase and says the potential sale is conditioned on compliance with section 38-12-217, C.R.S.
  • Home owners have the opportunity to assign their right to make an offer to buy the park to a public entity, like a local government or housing authority. If home owners enter into an assignment contract with a public entity, and other conditions in the statute are met, the public entity could have a right of first refusal to buy the park for the purpose of preserving it as long-term affordable housing. See section 38-12-217(8), C.R.S

Finalization or Moving Forward

If you reach an agreement with the home owners or their representatives, the process to finalize the sale can begin. If no agreement is reached by the end of the 120-day period, the seller can then proceed to sell the mobile home park to other buyers, but the initial offer and terms presented to the home owners must be maintained or the process starts over. See section 38-12-217(6)(b), C.R.S.

Compliance and Affidavit

After the sale concludes, regardless of the buyer, you must file an affidavit of compliance with the Division of Housing and your municipality or county, confirming adherence to the statutes governing the sale process. See section 38-12-217(11), C.R.S

By following these steps and adhering to the stipulations of section 38-17-217, C.R.S., sellers can navigate the 120-day waiting period effectively and in compliance with Colorado law, paving the way for a smooth and equitable sale process.

Non-Exempt Sale: File the Affidavit of Compliance
