What do appraisal quality ratings Q1 to Q6 mean?

Quality is how it was built. Condition is how it has held up.

Every appraisal on the standard forms carries two ratings for the house: a quality rating (Q1 to Q6) and a condition rating (C1 to C6). Agents mix them up constantly, and I get why. They sound like twins. They are not.

Quality describes the design, the materials, the finishes and the complexity of the construction. Condition describes wear, maintenance and repair needs. A custom home with hand-cut stone can be falling apart (high quality, poor condition). A basic tract home can be spotless (standard quality, great condition).

Freddie Mac's copy of the UAD 3.6 rating definitions says both ratings describe the property as of the effective date on an absolute basis. In plain words, the house is rated against the definitions, not against the neighbors. A Q4 house is Q4 whether it sits in a Q4 tract or next to a row of mansions.

These definitions come from the UAD 3.6 update that goes with the redesigned appraisal form. Freddie Mac's version is dated April 29, 2025, and copies the ratings from the URAR Reference Guide. Older reports may use earlier wording, so check which version a report was written under.

Q1 is the top of the scale and Q6 the bottom. Golf scoring for houses.

The six quality ratings in plain words

Here is a short version of each rating, based on the UAD 3.6 definitions Freddie Mac publishes:

The definitions also say a property has to meet the majority of the criteria for a rating, not every single one. A Q4 house with one fancy front door does not graduate to Q3.

What separates a Q3 from a Q4

The Q3 and Q4 line is where most of the arguments happen, so it's worth knowing the details the definitions actually list.

• Rooms. Q3 often has a large main living area or main bedroom, some vaulted ceilings and custom touches like built-ins, upgraded trim and moldings. Q4 has adequately sized rooms, mostly flat ceilings and basic trim.
• Kitchens and baths. Q3 kitchens have upgraded appliances, cabinets and counters. Q4 kitchens are standard grade, or a mix of economy and upgraded pieces.
• Outside. Q3 uses upgraded windows, doors, roofing and siding, with more complex rooflines and some angled walls. Q4 has standard-grade windows and doors, simple roofs with moderate pitch and walls that are basically rectangular.

Granite counters alone don't make a Q3. Neither does a listing description that says "luxury" four times. The rating comes from the overall design and the materials throughout, and a seller who installed a pot filler is going to be disappointed to hear it.

How quality differences get adjusted

A quality rating on its own is a label. The money comes from the adjustment, and that adjustment should be measured from real sales, not from a rule of thumb.

Fannie Mae's adjustment guidance says adjustments have to reflect how the market reacts to the differences between properties. For quality, that means looking at what similar homes of different quality actually sold for in that market. Paired sales, meaning two sales that are alike except for one main difference, are one of the cleanest ways to see it.

What I see in the field: buyers react to condition more than to age, and quality and condition get tangled together in their heads. A Q4 house that was fully redone can compete with a tired Q3 house. That doesn't change either quality rating. It means the condition line is doing its own work, and both lines need their own evidence.

Age is its own question, too. An older home can carry a Q3 rating if it was upgraded with premium materials, and a brand-new home can be a plain Q4. The year built tells you when. The quality rating tells you how.

When a grid shows a large quality adjustment with no support in the report, ask where it came from. Facts over feelings. "It felt nicer" is not a measurement.

What agents can do with the quality rating

1. Check the rating against the definitions. Read the subject's design, materials and finishes against the Q3, Q4 and Q5 lists. If it's clearly off, raise it with facts.
2. Check the comps' ratings, too. A comp rated Q3 next to a Q4 subject should carry a quality adjustment, or an explanation of why not.
3. Separate quality from condition in your comp packet. Say "same builder, same plan, remodeled kitchen" instead of "nicer house." The first one tells the appraiser which line to look at.
4. Bring paired sales if you have them. Two similar sales nearby, one semi-custom and one standard plan, are stronger evidence than any adjective.
5. Document upgrades. Materials, brands, dates and permits help the appraiser see whether an older home was upgraded with premium materials, which the Q3 definition specifically mentions.
