Data and Listing Disclosures

Where listing data comes from

Listing information on MHAuthority is supplied by participating multiple listing services. We receive it through a data feed, store it, normalize it into a consistent shape, and publish the portions we are permitted to publish. We do not create listings ourselves and we do not edit the substance of what a listing says.

Listing information is deemed reliable but is not guaranteed. It is provided for consumers’ personal, non-commercial use and may not be reproduced or redistributed.

How current it is

Our copy of the data is refreshed on a schedule rather than instantaneously, so there is always some delay between a change at the source and a change here. Every listing page shows when that listing was last updated. If a listing looks stale, that timestamp is the fact to check.

When a listing stops appearing in the feed, we mark it unavailable rather than deleting the page. That keeps your saved links and shared searches working. An unavailable listing is clearly labelled, is removed from search results, is excluded from our sitemap, and no longer carries any structured data claiming it is for sale.

What we exclude, and why

Our data feed contains the full inventory of the supplying services, including farms, commercial buildings, attached homes, vacant land, and site-built houses. MHAuthority is a manufactured-housing marketplace, so we exclude everything else.

That exclusion is done by an explicit rules engine rather than by keyword guessing. Every listing gets a recorded decision with the reasons attached, and the rules work primarily from structured property-type and manufactured-home fields. Listing remarks are never sufficient on their own to include a home, and a listing with conflicting signals is held for human review rather than guessed at.

The practical consequence is that our results are narrower than the raw feed by design. If you believe a genuine manufactured home is missing, or that something irrelevant has slipped through, tell us, those are both defects worth fixing and we would like to know.

Addresses we do not show

Some listings instruct us not to display the street address. Where that is the case we show the city and state only, and we label the listing accordingly. The street address is removed from the record when we ingest it, not merely hidden in the interface, so it cannot appear in a page’s source, an API response, a social preview, or our sitemap. Contact the listing professional if you need the address.

What we do not have

This is the part worth reading carefully.

• Verified community information.Our feed contains no community records. Community pages on this site are derived from the community name written on listings, grouped by exact name within a state. We have not verified any community’s amenities, rules, fees, lot availability, age restrictions, or whether it is resident-owned, and we do not guess. See any community page for the same disclosure in context.
• Lot rent, unless a listing supplied it.Where a listing includes lot rent we display it. Where it does not, we leave it blank. We never estimate lot rent, and a blank field means “not provided”, not “zero”.
• Age restrictions. We do not currently have reliable data on which communities are age restricted, so we do not label any of them 55+. Absence of that label means we do not know, not that the community is open to all ages.
• Resident-owned status. Same position. We will only describe a community as resident-owned when we have a reliable source saying so.
• Sold prices and sales history. We publish active listings. We do not publish closed-sale prices, and our market figures are based on asking prices, which are not the same thing and should not be read as evidence of what homes actually sold for.
• Agent performance data. We do not publish sales volume, transaction counts, or rankings for agents or dealers, and we do not assess them.

Statistics on this site

Where we show counts, homes for sale, homes for rent, communities represented, those are computed from the listings currently in our system, not from any external estimate of the market. We state which listing statuses contribute to a count and when it was calculated.

Where we publish a median price or similar figure on a location page, we only do so when there are enough comparable listings to make it meaningful. Below that threshold we say the sample is too small rather than publishing a number computed from two listings.

How our search ranking works

Our default “Recommended” sort weighs how complete a listing’s photographs and data are, how recently it was updated, and how confidently we classified it as manufactured housing. It is not price-ordered and it contains no paid placement. If we ever introduce sponsored placement it will be a separate, visibly labelled slot, not a hidden weighting.

Getting something corrected

We do not author listing content, so a correction to a price, description, photograph, or status generally has to come from the listing professional or the supplying service, we will publish it once the source changes.

That said, tell us anyway. If something is wrong we would rather know, and some problems are ours to fix: a misclassified property, a wrongly derived community grouping, a broken photograph, or an address shown that should have been withheld. Use our contact form and include the MLS number.
