Frequently asked questions
- What are red flags when inspecting a mobile home?
- Common warning signs include soft or sloping floors, roof and ceiling stains, separation at the marriage line on a multi-section home, signs of foundation settling or rust, modified electrical panels, and a missing HUD tag or data plate. This is general, educational information, not a substitute for a professional inspection — consider a licensed inspector familiar with HUD-code homes.
- Does a missing HUD tag matter on a mobile home?
- It can. The red HUD certification label and the interior data plate show the home was built to the federal HUD Code and record its design zones; missing or mismatched tags can complicate insurance, financing, and resale, and are worth asking about. This is general information, not legal advice.
