Short answer
They're Fannie Mae appraisal options where the appraiser doesn't visit the home. In a desktop appraisal, the appraiser works from records, photos, floor plans and other data. In a hybrid appraisal, a trained third party, such as a real estate agent or inspector, collects data inside and out, and the appraiser uses it. Fannie Mae's underwriting system decides when either is offered.
How does a desktop appraisal work?
Fannie Mae's Selling Guide (B4-1.2-02) says a desktop appraisal doesn't require the appraiser to inspect the home or the comparable sales. The appraiser can use public records, listing data, digital photos or videos, a floor plan and information from the owner or buyer, but must verify anything from someone with a financial stake in the deal. The report includes a floor plan, and it can't be made subject to a later check of the home's condition.
Which purchases can use a desktop appraisal?
- One-unit homes you'll live in, including homes with an accessory unit and homes in a planned community
- Purchases only, including new construction, with an Approve/Eligible result from Fannie Mae's Desktop Underwriter, and a loan-to-value within Fannie Mae's limit
Not eligible: condos, two- to four-unit homes, manufactured homes, second homes and investment properties, refinances, HomeReady and renovation loans, and homes with resale price restrictions.
How does a hybrid appraisal work?
Under B4-1.2-03, a trained and vetted person, such as a real estate agent, insurance inspector, home inspector or appraiser, collects interior and exterior data on the home. The appraiser then uses that data, plus other sources, to reach a value. Hybrid appraisals can be used for existing one-unit homes and condos, for primary residences, second homes and investment properties, on purchases and refinances. Two- to four-unit homes, co-ops, manufactured homes and renovation loans are not eligible.
What does this mean for me as a buyer?
- You don't pick the type. The lender chooses from the options the underwriting system offers.
- The value still has to support the price, so a low value is possible with any type.
- None of these replace a home inspection, which looks for problems for your own protection.
