Types of Real Estate Appraisals: How to Know Which One You Need

When people ask about the types of real estate appraisals, they mean two different things. The first is the appraisal format, or how the appraiser gathers information about your home. The second is the valuation approach, the method used to calculate what your home is worth.

This guide covers both, plus how to know which one you need. The main types include full, drive-by, desktop, hybrid, and FHA or VA appraisals, calculated through the sales comparison, cost, and income approaches. Hiring a local house appraising professional can help you sort out the right fit.

Which Appraisal Do You Need?

The right appraisal depends on your goal and who lends the money. Lenders order most appraisals to protect their loan. When you order one yourself, you control the timing and the format.

Common Types of Real Estate Appraisals

The format describes how the appraiser collects information about your home.

Full Appraisal (Form 1004 / URAR)

This is the standard interior-and-exterior appraisal. The industry uses the Uniform Residential Appraisal Report, known as URAR or Form 1004. It is the standard report for a single-family home.

The appraiser visits, measures, photographs, and evaluates your home's condition and comparable sales.

• Who orders it: Your lender on most home purchases.

• Best for: Buying a home with a mortgage.

• What to prepare: Clean access to every room and a list of recent upgrades.

Drive-By (Exterior-Only) Appraisal

The appraiser reviews only your home's exterior, along with public records and comparable sales. This format supports refinances and home-equity loans when the lender allows it.

• Who orders it: Your lender.

• Best for: Refinances and home-equity loans on established homes.

Desktop Appraisal

The appraiser values your home from data alone, without visiting the property. The Fannie Mae Selling Guide (B4-1.2-02) sets the rules for the Form 1004 Desktop. Its minimum scope of work does not include the appraiser inspecting the property or the comparable sales in person.

Fannie Mae requires a floor plan that shows interior walls and exterior dimensions. It allows desktop appraisals for one-unit primary homes with a loan-to-value ratio of 90% or less. Loan-to-value is the loan amount compared to the home's value.

This format is faster than a full appraisal. Review the desktop appraisal cost before you choose it.

• Who orders it: Your lender.

• Best for: Purchase loans with strong equity.

Hybrid Appraisal

A trained third-party property data collector inspects your home, and the appraiser uses that data to complete the report. The National Association of Realtors describes this as the property data collector inspecting the home instead of the appraiser.

• Who orders it: Your lender.

• Best for: Loans where a full appraiser visit is not required.

FHA and VA Loan Appraisals

These appraisals do double duty. They set your home's market value and check the property against minimum property requirements, the basic safety and condition standards a home must meet.

The HUD Handbook 4000.1 states that FHA-financed homes must be "safe, sound, and secure." VA loans require the home to meet the VA's minimum property requirements. These appraisals can flag repairs before your loan closes.

• Who orders it: Your lender.

• Best for: Buyers using FHA or VA financing.

• What to prepare: Address small safety and repair issues early, and review the FHA appraisal guidelines first.

The 3 Valuation Approaches

Appraisers calculate value using up to three approaches, and they blend them when the property calls for it. You can read more about how appraisers determine value before your visit.

Sales Comparison Approach

This approach compares your home to recently sold, similar homes nearby, called comps. Comps are comparable properties that show what buyers recently paid. It is the most common approach for residential property.

• Best for: Typical homes in areas with recent sales.

Cost Approach

Value equals what it would cost to rebuild your home today, minus depreciation, plus the land value. Depreciation is the loss of value over time. This approach is less precise than a full market value appraisal.

• Best for: New construction and unique or special-use properties with few comps.

Income Approach

This approach values a property by the income it produces. It relies on net operating income, or NOI, which is the income left after operating costs.

It also uses the cap rate, the annual return the property earns as a percentage of its value. This approach is not used for owner-occupied homes.

• Best for: Rentals, multi-unit buildings, and commercial property.

A full market value appraisal blends these approaches. That extra work is why it costs more, and why it satisfies lender and insurance requirements.

How to Prepare for Your Appraisal

A little prep helps your appraiser see your home at its best. Use this home appraisal checklist to stay organized.

• Clean and declutter every room so each space shows well.

• List your improvements and the dates you completed them.

• Note recent comparable sales in your neighborhood.

• Ensure the appraiser has access to every room, the attic, and the garage.

• Handle small repairs, such as loose fixtures or sticking doors.

Why the Right Appraisal Matters

An accurate appraisal helps you make an informed decision when you buy, sell, or refinance. It gives you and your lender a fair, data-backed view of what your home is worth.

On most home purchases, the buyer pays for the appraisal. Lenders use the result to help set your loan terms, so the number carries real weight. Review the home appraisal cost so you can budget for it.
