One of the most important steps in the mortgage process is the residential appraisal. Whether you’re purchasing or refinancing a home in Temecula, Murrieta, Menifee, Winchester, or the surrounding communities, the appraisal helps determine whether the property’s market value supports the requested loan amount and sales price for a purchase.
While buyers often think an appraisal is simply “checking the value,” today’s appraisal process is much more detailed and highly regulated.
A Brief History of Residential Appraisals
Residential appraisals have been used for decades to provide lenders with an independent opinion of a property’s market value. Before the housing crisis of 2008, it was common for loan officers and mortgage brokers to communicate directly with appraisers when ordering reports. Although most interactions were appropriate, concerns arose that appraisers could feel pressured to meet a desired value.
Following the housing crisis, appraisal independence became a major focus. Federal regulations and appraisal independence requirements were strengthened to ensure appraisers remain impartial and develop unbiased opinions of value based on market evidence—not the desired outcome of a transaction.
Appraisal Management Companies (AMCs)
Today, most mortgage lenders order appraisals through Appraisal Management Companies (AMCs). This process was introduced after 2011.
An AMC acts as an independent third party between the lender and the appraiser. The AMC assigns the appraisal to a qualified, state-licensed appraiser, manages quality control, and helps ensure compliance with federal appraisal independence requirements.
Although lenders pay the AMC, the appraiser remains an independent professional whose opinion of value cannot be influenced by the lender, loan officer, buyer, or real estate agent. Additionally, the appraiser cannot have direct communication with anyone from the lending-side.
What Is an Appraisal Waiver?
Not every mortgage requires a full appraisal.
For certain conventional loans, automated underwriting systems may determine that sufficient market data already exists and issue an appraisal waiver. When available, borrowers may avoid the time and cost of a traditional appraisal.
Appraisal waivers are generally not available for most FHA and VA purchase transactions because those programs typically require a full appraisal performed by an approved appraiser.
What Is SSR Scoring?
After many conventional appraisals are submitted, the report is electronically reviewed using automated risk analysis tools, including a Submission Summary Report (SSR).
The SSR compares the appraisal against extensive market data, previous appraisals, public records, and statistical valuation models. It may identify items for additional review, such as:
- Comparable sales selection
- Large adjustments
- Rapid appreciation
- Prior sales history
- Market trends
An SSR does not determine value. Instead, it helps underwriters identify appraisals that may require additional explanation or review. The scoring model is 1 for perfect and 5 for poor. Anything over 2.5 is a concern to Underwriting.
How Is a Home Appraised?
The most common valuation method for owner-occupied residential properties is the Sales Comparison Approach.
The appraiser compares the subject property to recently sold homes with similar characteristics, making adjustments for differences such as:
- Living area
- Lot size
- Bedrooms and bathrooms
- Condition
- Upgrades
- Location
- View
- Pool or other amenities
While the Cost Approach and, in some cases, the Income Approach may also be considered, the Sales Comparison Approach carries the greatest weight for most single-family homes.
Frequently Asked Questions
How long is an appraisal valid?
Most residential appraisals are generally valid for 90 days, although some loan programs allow extensions or appraisal updates under specific guidelines. Some allow up to 180 days.
Can an underwriter reject an appraisal?
Yes. If underwriting identifies material deficiencies, unsupported adjustments, missing information, or concerns raised through quality-control reviews such as SSR, the underwriter may request corrections, additional support, a reconsideration of value, or in rare situations, a new appraisal.
Can an appraisal transfer to another lender?
Conventional Loans: This used to be no. But more recently, transferring Conventional Appraisals has become transferrable from lender-to-lender as long as we receive the full electronic appraisal file, XML, SSRs, and proof the order was handled and performed under AMC provisions. This assumes from same borrower to a 2nd lender. Does not apply from one borrower to another borrower.
FHA Loans: Generally yes. FHA appraisals are assigned to the property through FHA systems and usually transfer between approved lenders while still valid.
VA Loans: Yes. VA appraisals stay with the property and may be transferred to another VA-approved lender if the loan changes lenders but not borrowers. VA Appraisals cannot be transferred from one borrower to another.
Is an appraiser an independent contractor?
In most cases, yes. Residential appraisers are state licensed or certified professionals who typically work independently or through appraisal firms while maintaining appraisal independence under federal regulations.
How far away can comparable sales be?
There is no single mileage rule.
- Urban neighborhoods: Often within 1/2 mile.
- Suburban areas: Frequently within one mile.
- Rural communities: Comparable sales may be 5 miles away when necessary to locate truly similar properties.
The goal is always to select the most comparable sales—not simply the closest.
Is an ADU included in the home’s square footage?
Generally, no. A legally permitted Accessory Dwelling Unit (ADU) is typically reported separately from the gross living area of the primary residence. However, the ADU may contribute additional market value depending on its size, quality, utility, and local market demand and as a separate structure.
Does a higher appraisal help me borrow more?
Not necessarily. Your maximum loan amount is determined by your loan program, qualifications, and the lesser of the purchase price or appraised value on a purchase transaction.
Can I include the value of my solar in the appraised value?
For most lending guidelines, solar can only be a line-item adjustment if it is paid for free-and-clear, not financed, not leased, and no PPA. Otherwise, no value given and deemed personal property.
Final Thoughts
Residential appraisals are designed to protect both borrowers and lenders by providing an independent, well-supported opinion of market value. Whether your loan requires a traditional appraisal or qualifies for an appraisal waiver, understanding how the process works can help reduce surprises and keep your transaction moving smoothly.
Working with an experienced mortgage professional can help you navigate appraisal requirements, answer questions throughout the process, and ensure your financing stays on track from application to closing.
