Why Property Condition Matters for Your Mortgage
When you apply for a conventional loan, the appraiser doesn't just determine your home's value. They also evaluate its condition and construction quality using Fannie Mae's standardized rating system. These ratings directly affect whether your loan can be approved and sold to Fannie Mae.
The appraiser assigns two separate ratings: condition (C1 through C6) and quality (Q1 through Q6). Think of condition as how well the home has been maintained, while quality reflects the original construction standards and materials used.
Say you're buying a 1950s ranch home that's been well-maintained but has basic finishes and standard construction. The appraiser might assign it a C3 condition rating (average condition) and Q4 quality rating (average quality). Both ratings are perfectly acceptable for conventional financing.
The Deal-Killers: Q6 Quality and C5/C6 Condition
Certain ratings make properties ineligible for conventional loans unless major issues are fixed first. Any property that receives a Q6 quality rating cannot secure a Fannie Mae loan until all quality deficiencies are corrected.
Q6 quality issues include properties that aren't habitable year-round, have minimal or missing electrical and plumbing systems, or contain substandard additions. Imagine a house where someone added a bedroom without proper electrical work or building permits, creating safety hazards. That addition could trigger a Q6 rating for the entire property.
Similarly, properties with C5 or C6 condition ratings are unacceptable until all condition problems are resolved. These ratings apply when serious deficiencies affect the home's safety or habitability.
C5 and C6 condition problems include active roof leaks, standing water, uncapped electrical wiring, missing exterior components that allow water intrusion, or non-functional mechanical systems. If you're buying a house with a leaking roof that's damaged interior walls, the appraiser will likely assign a C5 or C6 rating.
Required Repairs vs. Acceptable Minor Issues
Not every property defect kills a deal. Fannie Mae distinguishes between serious problems that must be fixed and minor issues that can remain as-is.
Minor acceptable deficiencies include worn floor coverings, small cracks in windows, damaged interior doors, missing cabinet hardware, dripping faucets that don't cause damage, and deteriorated sidewalks. These items might affect the home's value, but they don't prevent loan approval.
The key difference is safety and habitability. A dripping kitchen faucet is annoying but doesn't make the home unsafe. An active roof leak that's damaging interior walls creates serious habitability concerns.
When minor issues exist, the appraiser completes the report "as is" and may adjust the property value downward to account for needed repairs. You're not required to fix these items before closing, though you might want to negotiate with the seller about addressing them.
How Appraisers Handle Serious Defects
When an appraiser identifies serious problems, they complete the report "subject to" repairs or inspections. This means the appraisal assumes the problems will be fixed, but the loan cannot close until you provide evidence of completion.
For a property with foundation cracks, the appraiser might complete the report "subject to" a structural engineer's inspection. You'd need to hire the engineer, get their report, and provide it to your lender before closing. If the engineer recommends repairs, those must be completed too.
The same process applies to potential infestations or contaminated water sources. The appraiser flags the concern, and you must get appropriate professional inspections to verify whether problems exist and document any necessary remediation.
Non-Traditional Homes and Unique Properties
Fannie Mae accepts non-traditional property types like barndominiums, log homes, geodesic domes, and "shouses" (combined living and work spaces). The key requirement is demonstrating marketability through comparable sales.
If you're buying a barndominium in rural Texas, the appraiser needs to find other barndominium sales in your area to prove there's a market for this property type. If no similar properties have sold recently, the appraiser might use traditional homes as comparables but must explain and adjust for the differences.
The appraiser also evaluates whether unusual floor plans affect marketability. A home with bedrooms that connect directly to each other (tandem bedrooms) or a bathroom accessible only through the kitchen might be unusual, but it's not automatically disqualifying if similar layouts exist in the neighborhood.
Properties That Don't Conform to the Neighborhood
When your property differs significantly from surrounding homes in age, style, or construction materials, the appraiser must analyze how this affects value and marketability. A ultra-modern home in a neighborhood of 1960s ranches, or a log cabin surrounded by traditional suburban houses, requires special attention.
The appraiser looks for evidence that buyers in the area accept diverse property types. They might find that the neighborhood has several non-conforming homes that have sold successfully, demonstrating market acceptance of variety.
Outbuildings and Agricultural Concerns
Properties with barns, stables, or other outbuildings require careful evaluation to determine whether they're primarily residential or agricultural. A small decorative barn or horse stable might be acceptable if its value is minimal compared to the main house and similar outbuildings are common in the area.
Large barns, silos, or multiple outbuildings designed for farming operations can make a property ineligible for conventional financing, regardless of the main house's condition. Fannie Mae views these as agricultural properties that fall outside their residential lending guidelines.
The appraiser must demonstrate through comparable sales that outbuildings are typical for residential properties in your market area. A property with a small barn in horse country might be fine, while the same barn in a suburban subdivision could create problems.
What Documents You Need
Most improvement analysis requirements are handled by the appraiser, but you should prepare certain documents if your property has unique characteristics:
- Building permits for any additions or major renovations
- Professional inspection reports for any known issues (structural, pest, water quality)
- Documentation of recent renovations, including before-and-after photos
- HOA or neighborhood guidelines that might affect property modifications
- Any previous appraisals that addressed similar concerns
Common Problems That Surprise Buyers
Many buyers don't realize that unpermitted additions can affect their loan approval. Even if the work was done professionally, missing permits can trigger additional scrutiny and potentially delay closing while you obtain retroactive permits or professional inspections.
Another surprise is how seriously lenders treat water intrusion issues. What seems like minor roof damage to you might represent a serious habitability concern to an appraiser, especially if it's caused interior damage or mold growth.
Properties in transitional neighborhoods where home styles vary widely can also create appraisal challenges. Your mid-century modern home might be perfectly maintained, but if it's surrounded by Victorian houses and few similar properties have sold recently, the appraiser may struggle to establish value and marketability.

, which announced the policy requirements for Uniform Appraisal Dataset (UAD) 3.6. Sellers may submit to the Uniform Collateral Data Portal
®
appraisal reports that use UAD 3.6 before the mandatory effective November 2, 2026 version of this section.
This section contains requirements related to:
Property condition and quality of construction
Rehabilitated or renovated property
Non-conformity to the Neighborhood and non-traditional or unique property types
(a)
Property condition and quality of construction
The appraisal report must contain an accurate description of the improvements and describe any factors that may affect the market value or marketability of the subject property. The appraiser is responsible for reporting the condition and quality that best describe the overall condition and quality of the subject property.
For appraisal reports that are required to be completed using the Uniform Appraisal Dataset (UAD), the appraiser must use the condition and quality ratings and the level of updating definitions identified in
Exhibit 36, Condition and Quality Ratings and Level of Updating Definitions
. For appraisal reports that are not required to be completed using the UAD, the UAD specifications may be used to the extent they are applicable to the particular appraisal report form.
The condition and quality ratings must be based on a holistic view of the property and any improvements. When selecting the condition and quality ratings, the appraiser must:
Consider all improvements to determine overall condition and quality ratings and select the ratings that best reflect a holistic view of the property
If any portion of the improvements has a quality of construction consistent with the Q6 quality rating, the property must be identified with a Q6 quality rating
If any portion of the improvements is impacted by one or more deficiencies that are consistent with a C5 or C6 condition rating, the property must be identified with a C5 or C6 condition rating
Describe the subject property on an absolute basis as of the effective date of the appraisal report, meaning the property must be rated on its own merits.
Ratings should not be selected on a relative basis, meaning a rating is not selected based on how the property relates or compares to other properties. The condition and quality ratings for comparable properties must be made on an absolute basis and reflect the condition and quality of the comparable property as of the date of sale of the comparable property.
As necessary, provide additional commentary, descriptions and explanations to enable the intended users of the appraisal report to understand the property condition and quality
(i)
Properties consistent with a Q6 quality rating
A Mortgaged Premises consistent with a Q6 rating is not acceptable collateral to secure a Mortgage sold to Freddie Mac unless
all issues that caused the property to be rated with a Q6 quality rating are cured before delivery of the Mortgage to Freddie Mac. In such cases, when an appraisal report is delivered with the Mortgage, the appraisal report must be completed “subject to” and the reported quality rating must reflect the hypothetical condition that would exist if the repairs or alterations were completed.
Section 5605.8
for information related to appraisal reports completed “subject to” repairs or alterations and PDRs with required repairs.
Examples that are consistent with a Q6 quality rating include, but are not limited to:
Quality such that the property is not habitable as a year-round residence
Minimal or non-existent electrical, plumbing and/or other mechanical systems
Substandard additions to the original structure
Other quality related deficiencies that make the property unacceptable to typical purchasers in the Market Area
Exceptions:
Issues that caused the property to have a Q6 quality rating may be cured after the Settlement Date if:
®
Section 4607.1(b)
or a CHOICEReno eXPress
®
, and the:
Issues are cured as part of the completion of the renovations
Renovations are eligible renovations under
Section 4607.6
The Mortgage is secured by a property with incomplete improvements and delivered pursuant to
(ii)
Properties with deficiencies consistent with a C5 or C6 condition rating
A Mortgaged Premises with deficiencies consistent with a C5 or C6 condition rating is not acceptable collateral to secure a Mortgage sold to Freddie Mac unless
all issues that caused the property to be rated with a C5 or C6 condition rating are cured before delivery of the Mortgage to Freddie Mac. In such cases, when an appraisal report is delivered with the Mortgage, the appraisal report must be completed “subject to” and the reported condition rating must reflect the hypothetical condition that would exist if the repairs or alterations were completed.
Section 5605.8
for information related to appraisal reports completed “subject to” repairs or alterations and PDRs with required repairs.
Examples of deficiencies that are consistent with C5 or C6 rating include, but are not limited to:
Active roof leak(s)
Incomplete construction or remodel (including missing or severely damaged cabinets or countertops, missing plumbing fixtures in the kitchen or bathroom(s), etc.)
Missing or damaged exterior components that would allow water or other elements to enter the dwelling
Missing or severely damaged interior drywall or plaster such that the wall framing is exposed (excluding basements)
Standing water in the property, water seepage/intrusion or significant plumbing leaks
Curled, cupped or missing roof shingles
Missing or severely damaged floor coverings in the majority of the living area (excluding basements)
Damaged or failing foundations
A mechanical system that is non-functional, or
A sanitary system with evidence of failure
Exceptions:
Deficiencies that caused the property to have a C5 or C6 condition rating may be cured after the Settlement Date if:
The Mortgage is a CHOICERenovation Mortgage delivered pursuant to
Section 4607.1(b)
or a CHOICEReno eXPress Mortgage delivered pursuant to
, and the:
Deficiencies are cured as part of the completion of the renovations
Renovations are eligible renovations under
Section 4607.6
The Mortgage is secured by a property with incomplete improvements and delivered pursuant to
(iii)
Appraisal reports completed “subject to” an inspection
If there are property conditions that require further investigation, the appraisal report must be completed “subject to” an inspection by an appropriately licensed professional or another person trained in the particular field of concern.
Examples of conditions that may require an inspection include, but are not limited to, observations of:
Potentially contaminated water source
The Seller must include in the Mortgage file evidence of the repair or an inspection report that indicates the condition does not require repair. See
Section 5605.8
for additional information related to appraisal reports completed “subject to” an inspection.
(iv)
Existing properties with minor needed repairs or deficiencies or deferred maintenance
Freddie Mac allows an appraisal report to be completed “as is” for an existing property when there are minor needed repairs, deficiencies or deferred maintenance. The appraisal report must reflect adjustments for these conditions in the appraisal report, when necessary.
Examples of acceptable minor needed repairs, deficiencies and deferred maintenance items include, but are not limited to:
Damaged or missing interior doors
Damaged or missing window screens or cabinetry doors
Missing hardware (such as handles)
Missing light fixtures, electrical panel/breaker box covers, electrical switches or faceplates
Damaged or missing trim
Minor plumbing leaks that do not cause damage (such as dripping faucets)
(b)
Required permits
If there are additions or alterations that were made without required permits, the appraisal report should contain comments on the quality and appearance of the work.
(c)
Unusual floor plans
An unusual floor plan, such as a home with tandem bedrooms or a bathroom off the kitchen, does not make a property ineligible as security for a Mortgage delivered to Freddie Mac. The appraisal report should include commentary that addresses whether an unusual floor plan or similar obsolescence is found in other properties in the Market Area. To the extent possible, comparable properties should have similar obsolescence to demonstrate marketability and support value of the subject property.
(d)
Rehabilitated or renovated property
For properties that have recently undergone rehabilitation or renovation, the appraisal report must identify the changes made and contain photographs of the rehabilitation or renovation. The photographs must meet the requirements in
Section 5604.2(a)
.
(e)
Non-conformity to the Neighborhood and non-traditional or unique property types
When the subject property does not conform to its Neighborhood in terms of type, design, age, materials or techniques used in its construction, the appraisal report must reflect the effect of the nonconformance on the property’s value and marketability.
Mortgages secured by non-traditional types of properties are eligible for delivery to Freddie Mac. Examples of non-traditional or unique property types include, but are not limited to:
“Barndominiums” (barn conversions or barn-style buildings)
“Shouses” (living-space and work/storage combinations)
Geodesic dome dwellings
The appraisal report must include comparable sales that demonstrate the subject property’s dwelling type or style is marketable. Additional analysis may be required to determine whether the design or style represents a mixed-use configuration. (See
Section 5601.5
for mixed-use requirements.)
The appraisal report may contain traditional homes as comparable sales for non-traditional or unique properties if the appraiser identifies any differences between the subject and comparable sales and adjusts for any differences between the subject property and the comparable sales and can justify and support the use of the comparable sales in the appraisal report.
(f)
Outbuildings on a property
The Seller must consider outbuildings on a subject property, such as barns or stables, in the underwriting process to determine whether the subject property is primarily residential or non-residential. A subject property with a small barn or stable may be acceptable if the contributory value of the outbuilding is minimal in relation to the total appraised value of the subject property. The appraisal report must demonstrate (e.g., through the use of comparable sales, pending sales, listings) that these characteristics are typical for residential properties in the Market Area.
Note: When a subject property has a large outbuilding, such as a large barn or silo, or multiple outbuildings or facilities for farm animals, the subject property may be agricultural or non-residential and ineligible as security for a Freddie Mac Mortgage, regardless of whether the appraiser assigns value to these improvements.
