Used Container Home & Conex Box Homes — Buyer’s Guide

Used Container Homes: What to Check Before You Buy

Plenty of people start their search with “used container home” and end up buying new. Not because they got upsold, but because once you add up the real costs, a factory-built home often comes out cheaper and far less work.

That said, used can be the right call if you know what you’re looking at. Here’s how to tell.

Why people look at used first

The pitch is obvious: a used shipping container costs far less than a new one, and if it’s already converted, you skip the build. On paper it’s the affordable route.

What the paper doesn’t show is what condition the conversion is in, who did it, and whether it was done right.

The used conex box checklist

If you’re serious about a used container home, inspect these before any money changes hands.

  • Rust and pitting. Surface rust is fine. Deep pitting on the floor or walls means the steel is compromised. Walk the whole floor and press hard.
  • Floor condition. The original plywood floor rots from the inside. If it’s soft or smells musty, it needs replacing, and that’s a real cost.
  • Who converted it. A home is more than a box with windows. Check the wiring, the plumbing, and whether it was inspected. DIY conversions often aren’t.
  • Insulation. Most used homes have none, or thin foam that’s failing. Retrofitting proper spray foam into a finished container home is difficult and expensive.
  • Corner castings. These are the load-bearing points. Cracks or bent castings are a dealbreaker.

What used actually costs all in

A used container is maybe $1,500 to $3,500. A used container home, if you find one, runs $15,000 to $40,000 depending on condition and how much of it is finished. Then you pay to move it, which isn’t cheap for a unit that was never designed to be relocated once set down.

Once you add re-insulation, repairs, and the risk of hidden problems, the savings often shrink to nothing.

When new factory-direct wins

Here’s the honest comparison. A brand-new 20FT from us is $12,995, fully insulated, wired, and plumbed, ordered exactly how you want it. No surprises, no rot, no mystery wiring. For a lot of buyers, that’s less than a used unit of the same size ends up costing after repairs.

The 10FT starts at $7,995. That’s a new, finished home for less than many people pay for a used one that needs work.

Conex box, shipping container, storage container — same thing

You’ll see “conex box,” “shipping container,” and “portable storage container” used almost interchangeably. They all describe the same steel boxes. If you’re searching for a conex box home, you’re looking for exactly what we build.

The difference that matters isn’t the name. It’s whether the box was converted by a real manufacturer or someone with a welder and a weekend.

How to decide

If you find a used home that was built by a reputable company, inspected, and well insulated, it can be a good buy — get it inspected by someone who knows container construction.

If you’re looking at a shell someone converted themselves, or a unit with unclear history, price out new first. The gap is usually smaller than you think once the hidden costs come out.

Get a new-home price to compare

Before you commit to a used unit, get a firm number on new. Send us the size and your location, and we’ll quote it. Then you can weigh them side by side with real figures instead of guesses.

Frequently asked questions

Are used container homes cheaper than new?

Not always. Once you add re-insulation, floor replacement, repairs, and relocation, a used home often costs as much as a new factory-built one.

What is a conex box home?

A conex box home is a shipping container converted into living space. Conex box, shipping container, and storage container all refer to the same steel boxes.

What should I inspect on a used container home?

Check for deep rust or pitting, soft or musty floors, cracked corner castings, the quality of the wiring and plumbing, and whether the conversion was inspected.

How much is a used container home?

A used container home typically runs $15,000 to $40,000 depending on condition and how finished it is, plus relocation costs.

Is it better to buy new or used?

Buy used only if it was professionally built and inspected. Otherwise a new factory-direct home from $7,995 is often cheaper and far lower risk.
