When you’re in the market for a brand-new home, you may come across the terms “spec home” and “custom home.” But what’s the difference between the two, and which type of home will best suit your needs? This guide explores the differences between a spec home vs. custom home so you can make the best decision for your new abode.

Spec Home vs. Custom Home: Key Differences

Spec (or “speculative”) homes are built to builder specifications, either to use as model homes or to meet perceived market demand. These homes have several available floorplans, but you can’t deviate from their predetermined designs. Custom homes are purpose-built for you. You can design the floor plan and choose the styles and finishes—the end result is your dream home.

Spec Home vs. Custom Home: Plan Design

One of the main differences between spec homes and custom homes is who designs the floor plans. Custom builders near you design the floor plans of spec homes without a specific buyer in mind. They research the market to determine which features will appeal to the most buyers and create their plans based on that research. Buyers will have very few opportunities to customize the home; at most, they can choose between a few different layouts or opt for higher-end finishes.

Custom homes are designed for a specific customer. When choosing a custom home, you’ll work with the builder to create the floor plan based on your needs. Opting for a custom home means you will have a one-of-a-kind home that’s exactly what you want, rather than settling for a home that meets most, but not all, of your needs.

Another main difference between spec and custom homes is how long they take to build. Spec homes are often pre-built, so you can move right in without waiting on construction. If you opt for a spec home that hasn’t been built yet, the timeline is still relatively fast because the builder specializes in creating these exact homes, letting them complete construction quickly.

Custom homes take time to build. First, you’ll need to work with a builder, architect, and interior designer to bring your vision to life, and then you’ll have to wait on construction. A custom home can be an excellent option if you can wait several months to years for your home to be move-in ready. However, a spec home is the better choice if you're in a time crunch.

Spec Home vs. Custom Home: Financing

No matter which type of home you go with, you’ll need to determine how to pay for it. Unless you have a large amount of cash lying around, you’ll need to apply for a loan. However, the type of loan you get will depend on the kind of home you’re buying.

Spec homes are owned and sold by the builder. When you buy a spec home, you’ll typically get a regular mortgage to cover the purchase price minus your down payment. Upon closing, the bank will transfer the approved loan amount to the builder, and you’ll pay off the loan in monthly installments for the loan term (typically 15 or 30 years).

Financing for custom homes is a little more complex. You’ll need a construction loan, which is a short-term loan that finances the building phase. Once the house is built, you’ll need to convert the construction loan into a regular mortgage that you’ll pay off in monthly installments. You can either apply for a construction-to-permanent loan, which automatically converts the construction loan to a regular mortgage once the house is finished, or apply for a mortgage toward the end of the construction loan term.

Spec Home vs. Custom Home: Cost

The cost of building a home ranges from $139,000 to $526,000, with an average price tag of $320,000. In most cases, building a spec home is more affordable than building a custom home.  Pre-designed floor plans for spec homes typically cost between $500 and $5,000, while custom blueprints cost $5,000 to $20,000. Spec home builders will typically include the cost of the floor plan in the total cost of the home.

A spec home is the cheaper option if you’re on a fixed budget. However, you won’t be able to customize your home to your liking, so there’s a chance you’ll end up with features you don’t need or want. And if you choose upgrades offered by the builder, the cost of the home can climb quickly. Although custom homes are more expensive and take longer to build, you’ll end up with the exact home you want and won’t find yourself cursing the bathroom or closet design after a few years of ownership.

Frequently Asked Questions

No, squeaky floors do not always indicate structural damage related to a shifting foundation or subfloor damage. However, they may indicate underlying issues like loose subflooring, joists, or floorboards.

While it may not always be ideal, you can fix a squeaky floorboard without removing the carpet.

They may also use nails instead of screws if they suspect the pile will get caught in the screw. While some types of carpet will hide the screws and nails, a low-pile carpet may not.
