A home appraisal technically does not have a “pass” or “fail” grade. Instead, an appraisal can come in lower than expected or reveal issues that prevent a mortgage from being approved, which is often referred to as a “failed” appraisal in real estate transactions. Here are the main factors that can cause serious problems or lower the appraised value, potentially stopping a sale or mortgage approval:
- Low Appraised Value Compared to Sale Price
- If the appraised value is lower than the agreed-upon sale price, the lender may not approve the full loan amount. The buyer or seller must renegotiate, or the buyer must cover the difference with additional cash.
- Major Structural or Safety Issues
- Structural problems such as cracks in the foundation, roof damage, or significant water intrusion can make a home ineligible for most mortgages until repaired. These issues raise concerns about the home’s habitability and safety.
- Deferred Maintenance and Poor Condition
- Homes showing signs of neglect-such as peeling paint, broken fixtures, leaky roofs, or outdated systems-can see a significant reduction in appraised value. Excessive deferred maintenance may also make the property ineligible for certain loan types, especially FHA loans.
- Outdated or Failing Major Systems
- Old or malfunctioning HVAC, electrical, or plumbing systems can hurt an appraisal. These are costly to repair and may signal broader neglect.
- Pest Infestation or Damage
- Evidence of termites, carpenter ants, or other pests-especially if structural damage is present-can lower the value and may require remediation before a loan is approved.
- Location Issues
- Homes in less desirable areas (high crime, poor schools, proximity to noise or environmental hazards) tend to appraise lower. Market conditions, such as a declining neighborhood, can also impact value and loan eligibility.
- Unique or Hard-to-Value Properties
- Unusual homes or those in rural areas with few comparable sales can result in uncertain or lower appraisals, complicating the mortgage process.
- Over-Personalization or Unusual Renovations
- Highly personalized decor, unconventional room conversions, or unique finishes that don’t appeal to a broad market can negatively affect value.
- Fewer Bedrooms and Bathrooms Than Comparable Homes
- If your home has fewer bedrooms or bathrooms than similar properties nearby, it may appraise for less.
- Legal or Zoning Issues
- Unpermitted additions or code violations can delay or derail a mortgage approval, as lenders require properties to meet local regulations.
Summary Table: Common Reasons a Home Appraisal “Fails”
| Issue Type | Effect on Appraisal |
|---|---|
| Low appraised value vs. sale price | May halt or renegotiate sale/loan |
| Major structural/safety problems | Can make home ineligible for mortgage |
| Deferred maintenance/poor condition | Lowers value, may block loan approval |
| Outdated/failing systems | Reduces value, may require repairs |
| Pest infestation/damage | Lowers value, must be remediated |
| Location/market decline | Lowers value, may require bigger down payment |
| Unique/hard-to-value property | Uncertain/low appraisal, loan issues |
| Over-personalization | Narrows buyer pool, lowers value |
| Fewer beds/baths than comps | Reduces value |
| Legal/zoning/code violations | Delays or prevents loan approval |
Key Takeaway
A home “fails” an appraisal when its appraised value is too low for the agreed sale price, or when significant issues (structural, safety, legal, or market-related) are found that prevent a lender from approving a mortgage without repairs or renegotiation. Most of these issues can be addressed ahead of time to avoid surprises during the appraisal process.
