Service Detail

Estate and probate assignments require more than a quick value estimate. They require a credible opinion of value, careful effective-date analysis, and a report that can be understood by attorneys, fiduciaries, executors, beneficiaries, CPAs, and other professionals involved in the estate process. Cornerstone Appraisal provides retrospective date-of-death appraisals and current estate-related valuations throughout Maricopa County, Pinal County, and the Globe–Miami area of Gila County.

Common uses include probate filings, trust administration, estate settlement, step-up in basis, family transfers, and professional planning. Reports are written with clear support, local market analysis, and defensible comparable sales selection.

Service Detail

Divorce-related valuation often requires neutrality, discretion, and a report that both parties and their professionals can understand. Cornerstone Appraisal provides independent residential appraisal services for family law attorneys, mediators, and property owners who need credible valuation support during settlement or litigation.

Assignments may involve the marital residence, buyout scenarios, retrospective valuation, unique property characteristics, or questions about market exposure and contributory value.

Service Detail

When real estate value becomes part of a legal dispute, the appraisal must be clear, well-supported, and defensible. Cornerstone Appraisal provides residential valuation support for attorneys and clients involved in disputes where market value, property characteristics, or highest and best use are relevant.

Services may include appraisal reports, consultation, review of valuation issues, market research, and explanation of appraisal methodology in plain language.

Service Detail

Complex properties require experience, judgment, and market support. Not every home fits neatly into a subdivision model. Custom homes, rural properties, homes with acreage, luxury features, unusual design, guest houses, major renovations, green features, or limited comparable sales can require deeper analysis.

With nearly 30 years of Arizona appraisal experience, Cornerstone Appraisal is well suited for difficult residential assignments requiring careful comparable selection and credible explanation.

Service Detail

Cornerstone Appraisal provides residential appraisal services for lending-related needs including purchase, refinance, HELOC, private lending, and portfolio lending assignments. Local experience matters because Arizona neighborhoods, property types, and market segments can vary significantly across short distances.

Reports are developed with attention to market trends, condition, quality, location, and relevant comparable sales.

Service Detail

If your home has increased in value or your loan balance has declined, you may be eligible to request removal of private mortgage insurance. Many lenders require an appraisal or valuation process to determine whether the current loan-to-value ratio supports PMI removal.

Cornerstone Appraisal can provide an independent residential appraisal for homeowners exploring PMI removal. Always confirm your lender’s specific requirements before ordering.

Service Detail

When a home is purchased with cash, there may be no lender requiring an appraisal. That does not make an independent opinion of value any less useful. A cash-purchase appraisal can provide an additional layer of due diligence before a buyer commits substantial funds to a property.

Cornerstone Appraisal provides independent, market-supported residential valuations that can help buyers evaluate whether an agreed purchase price is reasonably supported by current market evidence, while considering the property’s condition, location, features, and relevant comparable sales.

Service Detail

Relocation decisions often involve important timing and financial considerations. An independent residential appraisal can provide a credible, well-supported opinion of market value for homeowners, employers, relocation professionals, attorneys, fiduciaries, and others involved in a move or property disposition.

Each assignment is developed with local Arizona market knowledge and careful consideration of the property’s competitive market, condition, location, and relevant sales activity.

Service Detail

Property tax assessments do not always reflect current market value or the specific features of an individual property. Cornerstone Appraisal can help homeowners understand whether an assessment appears market-supported and can provide valuation support when appropriate.

A well-supported appraisal can be useful when evaluating an appeal, discussing value with taxing authorities, or deciding whether the appeal process is worthwhile.

Service Detail

A high-performance home deserves an appraiser who understands what makes it different.

High-performance homes can include features that go well beyond conventional residential construction. As an Earth Advantage–accredited green appraiser, I have specialized training in evaluating homes with RESNET HERS® ratings, LEED® certification, Pearl Certification, solar photovoltaic systems, high-efficiency HVAC, enhanced insulation and building envelopes, energy-efficient windows, water-conservation features, and other sustainable improvements.

These features should be properly identified and analyzed in the context of the local market. The cost of an energy-efficient improvement does not automatically equal its market value; the appraisal considers whether buyers recognize and pay for those features and supports the conclusion with relevant market evidence when available.

Service Detail

Before listing a home, settling an estate, buying out a co-owner, or making a major real estate decision, an independent appraisal can provide valuable pricing clarity. A pre-listing appraisal helps reduce guesswork and can support a more informed pricing strategy.

Cornerstone Appraisal provides local, market-supported analysis throughout the Phoenix metro area, Pinal County, and the Globe–Miami area.

FAQ'sAboutAppraisals

Straightforward answers to common questions from homeowners, attorneys, fiduciaries, lenders, and other professionals.

What are the benefits of a professional appraisal?

Good real estate decisions start with reliable information. A professional appraisal gives you an independent, property-specific opinion of value supported by market data rather than a generic estimate.

Although mortgage lending is a common reason for an appraisal, an independent valuation can also be useful when you need to:

  • Set a reasonable asking price before selling a home.
  • Evaluate whether a purchase price is supported by the market.
  • Document value for insurance or financial planning purposes.
  • Resolve property disputes, partitions, divorce matters, or other litigation.
  • Analyze a property before a major investment or renovation decision.
  • Support relocation, estate settlement, or division of assets.
  • Evaluate a property tax assessment or other financial review.
  • Document sufficient equity for possible private mortgage insurance (PMI) removal.
  • Establish a well-supported property value for tax, estate, trust, or governmental reporting needs.
What should I ask before hiring an appraiser?

Before engaging an appraiser, make sure the person has the credentials, local knowledge, and assignment-specific experience needed for your property. Useful questions include:

  • Are you licensed or certified in Arizona?
  • What professional education, accreditations, or specialty training do you have?
  • How long have you been appraising residential real estate?
  • How familiar are you with this market area and this type of property?
  • Do you regularly handle assignments like estates, divorce, litigation, green homes, lending, or complex properties?
  • Are you familiar with the neighborhood and the competitive market?
  • What information will you need from me to complete the assignment efficiently?

For unusual or high-stakes assignments, competency in the specific property type and intended use can be every bit as important as general appraisal experience.

Why can't I just use an online real estate valuation site?

Automated valuation websites can be useful as a quick reference, but they are estimates produced by computer models. They generally cannot inspect the property or fully account for the details that often influence value: remodeling quality, condition, view, lot utility, functional design, landscaping, accessory improvements, energy-efficient features, or a rapidly changing neighborhood market.

A certified appraiser analyzes the specific property, researches relevant comparable sales, considers market reaction to important features, and explains the reasoning behind the value conclusion. For decisions involving estates, divorce, litigation, lending, taxes, or substantial financial consequences, that property-specific analysis matters.

How can I tell whether an appraisal report is credible and valid?

Start by confirming that the appraiser holds the appropriate Arizona license or certification for the assignment. A professional appraiser is also expected to comply with applicable appraisal standards and ethical requirements, including the Uniform Standards of Professional Appraisal Practice (USPAP).

A credible report should identify the property and intended use, describe the scope of work, analyze relevant market data, explain important adjustments or valuation judgments, and provide enough support for the reader to understand how the value conclusion was developed.

Arizona licensing information can be verified through the state's official appraiser licensing resources. USPAP is developed by The Appraisal Foundation.

Do you work with attorneys, estates, and other professional clients?

Yes. Cornerstone Appraisal regularly provides residential valuation services for estate and probate matters, date-of-death valuations, divorce and property division, litigation support, tax matters, complex properties, and other assignments where an independent and well-documented value opinion is important.

For legal and fiduciary work, I focus on clear communication, appropriate effective dates, defensible market support, and a report that can be understood by attorneys, clients, accountants, trustees, and other intended users.

What areas does Cornerstone Appraisal serve?

I provide residential appraisal services throughout all of Maricopa County and all of Pinal County, plus the Globe–Miami area and surrounding communities in Gila County.

Local market knowledge is especially important when neighborhood boundaries, property types, land influences, or buyer preferences vary significantly from one area to another.

How are green and energy-efficient homes appraised?

A high-performance home deserves an appraiser who understands what makes it different.

Green and energy-efficient homes often include features that go well beyond those found in conventional construction. Properly identifying, documenting, and analyzing these features requires an appraiser with specialized education and an understanding of how energy efficiency and sustainable construction may influence buyer behavior and market value.

As an Earth Advantage–accredited green appraiser, I have specialized training in the valuation of high-performance and energy-efficient residential properties, including homes with RESNET HERS® ratings, LEED® certification, Pearl Certification, solar photovoltaic systems, high-efficiency HVAC equipment, enhanced insulation and building envelopes, energy-efficient windows, water-conservation features, and other sustainable improvements.

A RESNET HERS Score provides a standardized measurement of a home's energy performance, while LEED-certified and Pearl-certified homes provide documented evidence of high-performance features and construction practices. These ratings and certifications can provide valuable information that should be considered as part of a well-supported appraisal rather than treated simply as upgrades on a property checklist.

Just as importantly, a green-certified appraiser understands that the cost of an energy-efficient improvement does not automatically equal its market value. The appraiser must analyze the local market to determine whether buyers recognize and pay a premium for these features and, when possible, support that conclusion with relevant market data.

Whether your property is a newly constructed high-performance home, a certified green residence, or an existing home that has undergone substantial energy-efficiency improvements, choosing an appraiser with specialized green-building knowledge helps ensure that these features are properly identified, documented, analyzed, and communicated in the appraisal report.

Your home may perform differently. It should be appraised by someone who understands why.

What information should I send when requesting an appraisal?

For the fastest response, email the property address, the reason for the appraisal, the effective date you need, any relevant deadline, and a short description of the property or circumstances. For retrospective assignments such as a date-of-death appraisal, include the historical valuation date. If the property has unusual features, recent renovations, solar or green certifications, acreage, a guest house, or other non-typical improvements, mention those as well.

The contact form below is designed to collect this information so I can review the assignment before responding.
