Why Might You Want to Build a Prefab Home in the Phoenix - Scottsdale Metro Area
Quick Build Times - prefab and modular homes are manufactured off-site and assembled at the final build site which allows for multiple steps of the project to be completed simultaneously and more efficiently than a traditional home build. This often results in shorter build times than traditional, site-built homes.
Cost Controlled - using a highly controlled build process (homes are manufactured in climate-controlled production and cutting facilities), unforeseen cost overruns can be better managed leading to reduced overall cost. This is especially necessary for high cost areas such as Phoenix, Scottsdale, Chandler, Glendale, and Queen Creek.
Sustainable & Modern - many of the prefab and modular home manufacturers that serve the Phoenix - Scottsdale area offer energy efficient, and in some cases, net-zero homes. Many of these manufacturers also offer modern designs, and high-tech elements and appliances.
Durable - manufacturers that serve Arizona offer products that are manufactured with consideration of the natural hazards of the area such as extreme heat and intense storms
Key Decisions to Make:
Home Location - while the initial cost to build a prefab home may be rather high in areas like Phoenix, Scottsdale, Chandler, Glendale, Queen Creek or the neighborhoods of North Scottsdale, Ahwatukee, and North Gateway, a newly-built prefab home in these areas can be a sound long-term investment. When considering where exactly to build your home, you should be mindful of a few things that could affect your project:
Slope of lot - steep hills can make it difficult to build most pre-designed prefabs, and may require a custom designed and engineered home
Set back requirements which can limit the buildable area of your property
Floor area ratio or other zoning protocols that may affect the possible size of the home
Whether or not your city requires a design review
Custom vs. Standard - While most builders offer a set of pre-designed floor plans, while some also offer options for partial or total home customization. Other builders may specialize in custom prefab home designs. If you live on a tricky lot (uneven terrain, small-lot size, etc.) you may face a limited offering of standard home designs that are suitable for your home build. Should you want to build a custom home in Phoenix, see our list of the best custom home builders in Arizona.
Modular vs. Kit Home v.s. Panelized - While all three of these construction techniques qualify as prefab home building techniques, there are nuances that you should know when building your own prefab house. These prefab home styles include:
Modular - homes are made up of multiple box-like modules. These modules are fully manufactured and assembled off-site and consist of floors, walls, ceilings, wiring, plumbing, and internal fixtures. After being assembled in an off-site facility, they are shipped to your desired location and the modules are connected and fastened to the foundation. Modular construction is one of the most affordable and quickest prefab building techniques due to the high degree of work completed off-site.
Kit Home - all materials and components necessary for building a home are pre-measured, cut, and delivered to the build site. In some cases, an owner builder can assemble the kit home themselves as a cost-saving method.
Panelized - the home’s structural components: walls, floor, ceiling, are manufactured separate from one another in off-site location. From there they are shipped and constructed at the final site like a traditional build. While somewhat similar to modular construction, panelized building offers more flexibility in the home build process.
Some builders advertise using Structural Insulated Panels (SIPs) which are a 2-in-1 combination of high-efficiency insulation and structural panels. This allows for the creation of a quick, energy-efficient prefab home.
Architect/manufacturer vs. All-in Company - There are many steps in the prefab home build process. Major steps include land acquisition, home design, manufacturing, and assembly. When selecting a company for your prefab home, you should also pay attention to the services your company offers. In some cases the company you choose may only offer a home design and therefore sub-contract out the manufacturing process, though this is not as common, as homes that offer both home design and manufacturing. This type of company however, still leaves you responsible for acquiring land and later finding a local builder to complete necessary site work and finish your home at the project site. It is worth noting that there are several companies that offer all-in-one services and can assist you in all stages of the home-build process including design, manufacturing, site work, and finishing your home.
Financing your home - unless you are planning to pay for your home in cash, you are likely going to need outside financing for your prefab home. The two most common ways of financing a prefab home build are:
construction loan - a short term loan that you can refinance once construction is complete
temp to perm loan - a construction loan for the duration of construction that converts to a normal mortgage once your house is finished. The advantage of these loans is you only have one mortgage close vs. two with just a construction loan.
These methods usually allow you to finance both the land purchase and the construction of your home however, the underwriting and approval process on these loans can be lengthy (60+ days) as the bank is not only underwriting you as a borrower, but also the viability of your building plans. To get land more quickly, buyers will often pay cash for their building lot and then the lender will credit the land purchase as a down payment percentage on the purchase.
Some of the best lenders for these products only operate regionally. Therefore, if you would like assistance specific to your situation, we can provide recommendations here.
If you’re looking to purchase an ADU (accessory dwelling unit) or tiny home, then you may want to consider a personal loan:
Many personal lenders allow you to borrow up to $100k with no down payment
These loans are typically amortized over a shorter period than mortgages (up to 12 years)
These loans typically don’t underwrite the property and instead underwrite you as a borrower
Many of the best personal lenders are online and serve almost the entire country
The time to get approved for a personal loan is generally pretty fast (as little as a day to up to a couple weeks)
Common Questions
How much will it cost to build a prefab house in Phoenix, Arizona?
While certain variables such as location, builder, and floor plan will affect the total cost of building your home, it is our experience that the final cost of your prefab will range between $180 - $445+ (as of March, 2020).
Is a prefab home a good investment?
Yes, in areas where the total cost of building your prefab home (land cost + building costs) is less than the average dollar per square foot sales price of homes in your neighborhood i.e. you are able to sell your home for more than it cost to build it. In the Phoenix - Scottsdale area that includes areas where the average price per square foot is $275 per sq ft or higher. This includes multiple neighborhoods of Phoenix and Scottsdale such as North Scottsdale, Ahwatukee, and North Gateway as well as surrounding cities such as Chandler, Glendale, and Queen Creek. It is important to note that the hardest part of a project in these areas is finding buildable land or even lots suitable for tear-down that will work within the price range and time frame of your project.
Can I finance a prefab home in the Phoenix - Scottsdale Area?
Yes. The most common way to finance a prefab home is a temp to perm loan. This financing method starts out as a loan for the construction of your home and converts to a mortgage once your home is completed. Another financing option is a construction loan which is a short-term loan that you then refinance once the construction process is finished.
What do the economics of an investment in a prefab home look like?
Our spreadsheet (below) is an example of what the costs and potential benefits of a prefab home investment might look like. While there may be high up-front costs, it is likely there will be a sizable return on your investment. In high-demand areas of Phoenix and Scottsdale, one of the most challenging parts of the build process is finding a buildable lot at a reasonable price. In some cases it might be cheaper to buy and tear-down an existing home rather than purchase a vacant, build-ready lot.
