The Pros and Cons of Prefab Homes - SmartAsset

If you can’t find a house you want to buy you may be tempted to build your home yourself. In that case, you’ll need to choose between a stick-built house and a prefab home. Stick-built means your home is built the old-fashioned way, with a crew of workers on site for months raising the home and fitting it with plumbing and electricity. A prefab home, on the other hand, comes in pre-built parts.

What Is a Prefab Home?

The term “prefab” is the abbreviation for prefabricated, which is all you need to know about prefab homes. These houses are manufactured in a factory setting and transferred immediately as full build. As you might expect, this type of home is extremely easy to make and move in comparison to a traditional home.

Prefab homes come in three main iterations: manufactured, kit and modular. Here’s a brief breakdown of each:

  • Manufactured homes: A home in this category is built in sections and pieced together by professionals and heavy machinery at its final site. These must follow HUD requirements, though.
  • Kit homes:  These homes are much simpler than a manufactured home, though they follow a similar style of building. In fact, most homebuyers can build a kit home themselves.
  • Modular homes: These homes feature much more personalization, companies will often let you customize the floor plan of your purchase. However, unlike manufactured and kit homes, modular homes have an immovable foundation.

The Pros of Prefab Homes

Exceptional Energy Efficiency

One of the benefits of prefab homes is that they tend to be highly energy efficient. Their tight seams and state-of-the-art windows keep heat in and reduce your energy bills in the process. As a bonus, modular homes’ tight construction gives them a reputation for being able to withstand natural disasters. If you ask many people “What is a prefab house?” they’ll assume it’s the same as a mobile home. Not true. Prefabricated (aka modular) homes go into a foundation like any other home. They can be high-quality, modern and elegant houses perfect for those who want a lower carbon footprint than the typical American suburban home has.

Fast Construction

Fast construction is one of the big advantages of prefab homes. Because the parts of a prefab home come ready, all you have to do is assemble them and hook up the home to utilities. Hence the name “modular.” The prefab goes up much faster because it arrives partially constructed. That means fewer days with laborers on site and less vulnerability to weather delays and illnesses that can extend the construction process by days and weeks. Still, there’s more to consider than just the construction time. Site preparation, including obtaining permits, can be a lengthy process.

Affordability

Building a prefab home is generally less expensive than building a comparable stick-built home. Nice, right? Part of the savings has to do with labor. It takes fewer laborers working over the course of fewer days to make a prefab move-in ready. That saves you money. Plus, as we mention, heating and cooling tend to be more affordable with prefab homes than with regular ones. If you’re open to buying an existing home, compare the costs of what’s available on the market with the cost of building a prefab. And remember that various levels of fittings and customization can raise or lower the cost of your prefab. Talk to the manufacturer about cost-cutting strategies available to you.

The Cons of Prefab Homes

Land Costs

If you want to put up a prefab home you’ll need to own the land underneath it. If you don’t already own land you’ll need to buy it. You’ll also need to make sure that you’re able to put up a prefab home on that land, and that you can hook it up to electricity, water and sewer. And don’t forget soil testing on the land you’re planning to call home. Securing the land, inspections and permits can add up in terms of cost, time and trouble. Some companies that sell prefab homes will help you with this process, securing permits on your behalf and rolling their expenses into the cost of your modular home.

More Up-Front Payments

If you buy an existing home you can make a down payment of around 20% and pay off the rest of your mortgage over time. While financing and construction loans are available for many prefab homes, you’ll need to pay for the home’s construction before you move in. Your contract will include a schedule for paying in installments while your home is under construction. This pay-as-you-go feature of prefab homes means you need to be extra sure you can afford the prefab before you commit to buying it and putting it up. On the other hand, paying more up front saves you money in interest.

Utilities Might Be Tough to Find

One of the disadvantages of prefabricated houses is that it can be tough to arrange for utilities and other site details. If your site is uneven you’ll need to have it leveled. Then you’ll need to lay the foundation and arrange for sewer strikes and electrical connection, not to mention connecting to city water or finding well water. If this all sounds a little too daunting, look for a prefab home that comes with the option to have the prefab home company take care of these details for you.

Bottom Line

The cost of a prefab home will vary depending on how much you’re willing to do yourself and how much you outsource to others. Some ambitious home purchasers prefer to buy a prefab home as a kit and assemble it themselves, with the help of a few friends. Others are happy to spend the money to have the details of construction and permitting taken out of their hands. Wherever you fall on the spectrum, make sure you understand what you’re getting into before you go the prefab route.

What Is A Prefab Home? A Home Buyer's Guide | Quicken Loans

If you’re looking for an affordable home that allows you to have the designs and even floor plans you want, consider a prefab home. These types of homes have come a long way, giving today’s home buyers many more options than before to buy a home of their dreams.

What Is A Prefabricated (Prefab) Home?

As you determine the type of home that’s right for you, prefabricated homes may be an option. A prefabricated, or prefab, home is built in a factory instead of on the land it will sit on. Prefab homes may be built entirely in the factory and delivered as an entire house or shipped in pieces and put together on-site.

Like stick-built homes, you can choose your home design, getting the floor plan and features you want in a new home. In addition, depending on the type of prefab housing you choose, you’ll have different options for foundation types.

Types Of Prefab Housing

Prefab homes come in several designs and with several floor plans. The type you choose determines how the house is constructed and whether it’s transferred as a fully built home or in prefabricated parts.

  • Manufactured homes: Manufactured homes are built in sections in a factory on a chassis and then assembled on-site. HUD has strict construction and safety standards for these homes to ensure longevity and security. Typically to get mortgage home financing on manufactured homes, they must be permanently affixed to the land, built on or after June 15, and have a HUD tag. FHA loans for manufactured homes require a foundation inspection according to the standards set by the Permanent Foundations Guide for Manufactured Housing. If you’ve had a prior inspection, that can be used to qualify.
  • Modular homes: Modular homes are also built in pieces off-site and then put together on-site, but they’re not built on a chassis. Most builders allow more freedom with floor plans and home design with modular homes, and they are built on a permanent foundation. The house is delivered in multiple prebuilt pieces and assembled with a crane on site. When completed, it looks no different than a stick-built home.
  • Kit homes: Kit homes come in already-built pieces that are put together on-site. They are known as “ready-cut” homes and are simple enough for homeowners to build themselves. The most common example of kit homes are log cabins, but recently tiny houses have become a popular type of kit home.
  • Panelized homes: Panelized homes are built in sections and placed on a permanent concrete foundation on site. They usually come in a floor system, interior/exterior walls and roof trusses. The foundation is built first, then the home is shipped to the site and assembled.

The Average Cost Of Prefab Homes

The cost of prefab homes can vary widely depending on the home design, type of foundation and floor plans. On average, homebuyers pay $50,000 – $300,000 for a prefab home. This can be one of the cheapest ways to build a house because of the mass production of materials. This allows home builders to purchase home parts in bulk, paying much lower prices.

Other reasons prefabricated homes are so cheap include the following:

  • Less construction work and labor required
  • No weather delays because the new home is built indoors
  • Bulk building parts of the home reduces the cost of parts and labor

Prefabricated Home Financing Options

Like any home, you likely need financing when buying prefabricated homes. However, unlike stick homes, your options may be more limited. Here are a few financing options.

  • Manufactured home loan: Some lenders offer traditional financing for prefabricated homes, but not all. If you have excellent credit, money to put down and a low debt-to-income ratio, you might qualify for conventional or government financing, such as FHA or VA loans. It depends on the home’s classification and if it’s permanently affixed to the ground. Availability of manufactured home loans via traditional methods varies by lender.
  • Construction loan: A construction loan has two parts. The first is the financing to build the prefab home. It covers the cost of materials and labor. Construction loans only require interest payments during construction, but you’ll need at least a 620 credit score and 20% down on the home to qualify. After the construction phase, the loan may convert to a permanent mortgage with principal and interest payments due like a standard mortgage, or else you’ll need to refinance into a permanent mortgage.
  • Chattel mortgage: If you can’t find traditional financing for your prefab home, a chattel mortgage may be an option. This financing is used on other items, such as boats and cars, and is most common for homes considered mobile homes. They have shorter terms, but you don’t have to own the land the home sits on, making them a popular option for some.

Prefabricated Homes Pros And Cons

Prefab homes have pros and cons. When considering buying versus building a house, you should consider both sides.

Prefab Home Pros

  • Affordable: Prefab homes cost less to build and require less labor. This lowers the overall cost of prefab homes, allowing more people to build houses.
  • Sustainable: Prefab homes have tighter seams and use energy-efficient windows, which increases the home’s energy-efficiency, lowering your overall costs and protecting the environment.
  • Quality construction: Homebuilders give home buyers many options when building a prefabricated home, including floor plans and home design. The materials used are usually state-of-the-art and withstand all elements.
  • Safety: Thanks to HUD regulations, prefab homes are safe from the weather extremities and other elements that could put your home or family’s lives at risk.

Prefab Home Cons

  • Zoning laws: You might be unable to build your prefabricated home where you want if it doesn’t meet the local zoning regulations.
  • Setting up utilities: Depending on the home’s location, it could be hard to set up water and other utilities, and when you do set them up, they can be costly.
  • Upfront costs: You may have a lot of upfront costs if you don’t use construction loan financing since you’re fronting the cost of building the home versus buying an existing home.
  • Financing limitations: Not all lenders offer prefab housing loans, and if they do, the restrictions can be tight, such as needing a large down payment or higher than normal credit score.

Prefab Home FAQs

Prefab homes are popular and affordable for home buyers. Here are some common questions people ask regarding them.

What’s the difference between a modular home and a prefab home?

Prefab homes come in many types, including modular homes. These homes are built on an assembly line and delivered to the home site for assembly. They are usually cheaper than stick-built homes because some of the labor is done via assembly lines, decreasing labor costs.

Where can I buy a prefabricated home?

You can buy prefabricated homes in many areas. Companies like Plant Prefab and even Amazon sell prefabricated homes.

How long does it take to build a prefab house?

On average, building a prefab house takes four to six months. This is much faster than it takes home builders to build a traditional house, mostly because some work is done in bulk, and there aren’t any weather concerns with work done indoors.

Are prefabricated houses worth it?

Prefabricated houses can be worth it if you’re looking for an affordable home that you have a say in the home design. The cost of prefab homes can be attractive, and today’s quality building methods make them highly sought after.

The Bottom Line

A prefab home can be a great option whether you’re on a budget, want an energy-efficient home, or want to streamline the home buying process.
