Research question
How can a manufactured-housing operator use public information about property-type analysis without turning a national dataset, program directory, or screening tool into an unsupported conclusion about one property, resident, borrower, or transaction?
Finding
The source can support comparisons only within its published definitions, geography, period, and coverage. It can frame questions and identify records worth checking. It cannot prove a particular home's condition, value, compliance, safety, eligibility, financing result, or local risk.
Method and source record
Begin with the publishing agency. Record the page or table name, URL, access date, release period, universe, geography, unit, filters, and revision status. Save the exact extraction steps so another reviewer can reproduce the result.
| Review field |
Required note |
| Publisher |
Agency and program responsible for the source |
| Universe |
Homes, loans, households, places, or records included |
| Measure |
Official definition, unit, and exclusions |
| Time |
Reference period, release date, and revision status |
| Geography |
National, regional, state, county, tract, or other unit |
| Limits |
Sampling, suppression, missing coverage, and local gaps |
Keep the agency's statement separate from MobileHomeBiz interpretation. If a table is revised or replaced, retain the earlier extract and note the change.
Appropriate use
Use the material to describe the stated population, compare compatible releases, document a screening question, or plan which local sources to retrieve. Confirm that figures share the same universe, unit, geography, period, and revision status before placing them side by side.
A virtual assistant may maintain citations, downloads, filter notes, and review dates. The assistant should not make lending, legal, appraisal, engineering, insurance, tax, safety, or compliance decisions.
Scope and limitations
Administrative data reflect the program that collected them. Surveys can include sampling error, nonresponse, imputation, and disclosure protections. Directories may show administrative responsibility without resolving a specific case. Screening tools aggregate indicators and do not replace site investigation. An association is not proof of causation, and a missing record is not proof that an event did not occur.
For property-level action, pair public information with the applicable title, permit, inspection, loan file, map determination, utility record, contract, or professional analysis. Clearly label proxies and unavailable values.
Reproducibility check
Test every citation. Confirm the publisher and source title, keep units beside values, and have a second reviewer repeat a sample extraction. If the result cannot be reproduced, correct the method note before publishing a conclusion.
