Non-Disclosure Map & Info

The Full List of Non-Disclosure States

Above is a map that displays all of the non-disclosure states in the U.S. This is solely for informational purposes and the list may change at any time please do your own due diligence, but this can serve as a general guide. Certain data is not available for all states. These states are known as non-disclosure states, and if you're working in one of these geographic areas, there will be some barriers between you and the information you need. If you’re an investor, consider partnering with Realtors to get access to the MLS for full property data access.

For ease of understanding, the map uses a color-coding system above:

  • Green represents “full disclosure” states, where the sale prices of properties are openly reported and accessible to everyone.

  • Red denotes “non-disclosure” states, where no reliable public sources are available to obtain sale prices for all properties.

  • Orange indicates states that fall in between, with limited disclosure. In these states, making an educated guess about property values is possible based on the partial information disclosed to the public.

When looking at this map, it's important to understand that “non-disclosure” means slightly different things in different states. It ultimately comes down to whether the sale price must be disclosed to the local assessor, and if so, who can see that information. In some states, only the assessor or certain officials may access sale prices, while in others, the information is never made public.

If you’re working in a non-disclosure state, expect limited transparency on property sale prices. This can make it harder to determine fair market value or appeal property tax assessments. In most cases, access to real estate market data depends on the Multiple Listing Service (MLS), which is available to licensed real estate professionals.

Here is the full list of non-disclosure states in the U.S. as of 2025:

  • Alaska

  • Idaho

  • Kansas

  • Louisiana

  • Mississippi

  • Missouri (partial; some counties are non-disclosure, while others require disclosure)

  • Montana

  • New Mexico

  • North Dakota

  • Texas

  • Utah

  • Wyoming

In these states, property sale prices are not required to be made public, which can impact market transparency and property tax assessments. Missouri is unique in that only certain counties are non-disclosure, while others mandate disclosure of sale prices.

What else should I know?

Non-disclosure status significantly impacts your ability to access property values because, in these states, the final sale prices of properties are not made part of the public record. This means:

  • Public Records Lack Sale Prices: You cannot look up what a property sold for through county or state public records. This limits transparency for buyers, sellers, and investors.

  • Difficulties in Determining Market Value: Without public sale price data, it's much harder to find accurate comparables (comps) for appraisals, pricing, or investment analysis. Automated valuation models and online estimates are often less reliable in these states due to incomplete data.

  • Information Asymmetry: Buyers not working with a real estate agent, and especially non-local buyers, have far less access to accurate market trends and comparable sales, creating an uneven playing field.

  • MLS Access Becomes Crucial: Real estate agents and brokers with access to the Multiple Listing Service (MLS) can still see sold data and provide it to clients, but the general public cannot access this information directly. Investors and buyers often need to partner with an agent to obtain reliable comps and sales data.

  • Potential for Appraisal Bias: Appraisals in non-disclosure states can be more biased, especially for financially constrained borrowers, leading to higher rates of mortgage default and inaccurate property valuations.

  • Challenges with Property Tax Assessments: Without access to recent sale prices, property tax assessments can be less accurate, sometimes resulting in inequities or “sticker shock” for homeowners after a reappraisal.
