How Appraisals Work for New Construction Homes

If you’ve been through the homebuying process before, you probably know that a home appraisal is typically part of getting a mortgage. An appraiser visits the property, evaluates its condition and features, and assigns a market value that helps the lender determine how much they’re willing to lend.

But what happens when the home you’re financing doesn’t fully exist yet? That’s the reality for many buyers pursuing new construction. It raises a fair question: how can a lender or appraiser determine the value of something that hasn’t been built?

The answer involves a process that’s a little different from a standard appraisal, and understanding it can help you feel more prepared as you move through the financing process.

What Is a New Construction Appraisal?

A new construction appraisal is an evaluation of a home’s projected value based on what the finished property is expected to be worth. Because the home may be partially built or not yet started, the appraiser works from a combination of:

• Architectural plans and blueprints
• Builder specifications (materials, finishes, square footage, lot details)
• Comparable sales of similar homes in the area (known as “comps”)
• The location and characteristics of the lot

This type of appraisal is sometimes referred to as an “as-completed” or “subject-to” appraisal because it’s assigning a value to the property subject to the completion of the described construction. In short, it’s a forward-looking estimate grounded in the information available today.

Why Does the Appraisal Matter for Construction Financing?

Whether you’re taking out a construction loan to build from scratch or financing a newly built home through a traditional mortgage, the appraisal plays an important role in the process.

For a construction loan specifically, lenders use the appraised value to determine how much funding they’ll authorize for the project. The loan amount is typically based on the lesser of the total project cost or the appraised as-completed value.

This aims to protect both the lender and the borrower in that the lender isn’t funding more than the projected value, and you as the borrower have a built-in checkpoint on whether the planned project is financially sound.

If the appraisal comes in lower than expected, it can affect your financing options or require changes to the project scope. This is one reason it’s helpful to work closely with your builder and your lender early in the process.

How a New Construction Home Appraisal Is Different

Because the appraiser can’t walk through a finished home, they rely heavily on documentation and market data. Here are the key factors that generally influence a new construction appraisal:

Plans and Specifications

The appraiser will review detailed plans and builder specs to understand the size, layout, and quality of the home being built. More detailed documentation typically leads to a more accurate appraisal.

Comparable Sales (Comps)

The appraiser will research recently sold homes that are similar in size, style, and features in the surrounding area. In newer developments, they may use other homes from the same builder or subdivision as comps. In areas with limited new construction, finding strong comps can be more of a challenge and may require the appraiser to look at a wider geographic area.

Location and Lot Characteristics

Where the home is being built is bound to affect its value. The appraiser considers the neighborhood, proximity to schools and amenities, lot size, topography, and any easements or encumbrances on the property.

Materials and Finishes

The quality of the materials and finishes specified in the build, from flooring and cabinetry to roofing and windows, influences the appraiser’s assessment. Upgrades can add value, but it’s worth knowing that not every upgrade adds dollar-for-dollar to the appraised value.

What Happens After Construction Is Complete?

Depending on the type of financing you’re using, there may be a second appraisal, or at minimum an inspection, once the home is finished. For a construction-to-permanent loan (where the construction financing converts to a mortgage upon completion), the lender may require a final inspection to confirm that the completed home matches the plans and specs used in the original appraisal.

If there have been significant changes to the scope of the project during construction, the value may need to be revisited. Staying in close communication with your lender throughout the build can help you stay ahead of any potential issues.

What Happens If a New Construction Appraisal Comes in Low?

Sometimes the appraised value of a new construction home comes in lower than expected. When that happens, it doesn’t always mean the project can’t move forward, but it may first require adjustments to the financing or the construction plans.

Here are a few common ways buyers and builders address a low appraisal:

Add additional cash to the project

If the appraisal comes in below the expected value, you may choose to contribute additional funds to cover the difference between the appraised value and the project cost.

Adjust the construction plans

In some cases, scaling back certain upgrades, finishes, or design elements can help bring the overall project cost closer to the appraised value.

Builder concessions

A builder may agree to reduce the purchase price or absorb certain costs to help keep the project aligned with the appraised value.

Renegotiate the purchase terms

Depending on the contract and stage of construction, buyers and builders might renegotiate certain terms of the agreement to move the project forward.

Key Takeaways

• New construction appraisals are forward-looking. Because the home may not be finished yet, appraisers evaluate projected value based on plans, specs, and comparable sales.
• The appraisal influences how much your lender will fund. For construction loans, the authorized loan amount is typically based on the lesser of the project cost or the appraised as-completed value.
• Comps, location, and build quality all matter. Appraisers weigh a range of factors, from nearby comparable sales to the materials and finishes specified in your builder’s plans.

Final Thoughts

Building a new home can be one of the most personal and exciting things you can do. But the appraisal is a part of that process, too. And while the appraisal process for new construction is a bit different from a standard home purchase, it doesn’t have to be intimidating once you get what it involves.

At its core, a new construction appraisal is there to establish a credible, data-backed estimate of what your finished home will be worth. That way, your lender can fund the project more confidently, and you can move forward knowing the numbers make sense.
