How do you check the age of a property? ——The impact of building age on property value and its evaluation method
When buying or investing in property,Building ageis a key factor that cannot be ignored. It not only affects the living comfort of the house, but is also closely related to the loan period, future appreciation potential, etc. Recently, discussions on topics such as "renovation of old communities" and "age restrictions on housing in school districts" have been hot across the Internet. This article will combine structured data to analyze the importance and evaluation methods of building age.
1. Definition and classification of building age

The age of the building refers to the time span from the date of construction to the present. According to market practice, it is usually divided into the following categories:
| Building age classification | Year range | Features |
|---|---|---|
| new house | 0-5 years | New facilities, easy loans, but higher prices |
| sub-new house | 6-15 years | High cost performance, mature community |
| old house | 16-30 years | Facilities may be aging, but location advantage is obvious |
| dilapidated house | More than 30 years | Structural safety needs to be assessed, making it difficult to obtain a loan |
2. Three major impacts of building age on real estate
1.loan restrictions: Banks are stricter in approving housing loans for properties over 20 years old. Some cities stipulate that "house age + loan term ≤ 50 years".
2.cost of living: Maintenance costs for older homes (e.g., plumbing, elevators) can increase significantly.
3.Appreciation potential: Old houses in core areas may appreciate in value due to demolition or renovation, but old houses in non-core areas have poor liquidity.
3. How to accurately obtain building age information?
| channel | method | Things to note |
|---|---|---|
| Real estate certificate | Check "Registration Date" or "Built Year" | Some old houses may have been renovated and require on-site inspection. |
| Housing and Urban-Rural Development Department | Query original house files | Proof of property ownership required |
| Community property | Inquire about completion record form | Information may be incomplete |
4. Correlation data between building age and housing prices (taking first-tier cities as an example)
| city | Average price of new homes within 10 years | Average price of houses over 20 years old | spread ratio |
|---|---|---|---|
| Beijing | 82,000 yuan/㎡ | 65,000 yuan/㎡ | -20.7% |
| Shanghai | 78,000 yuan/㎡ | 59,000 yuan/㎡ | -24.4% |
| Guangzhou | 45,000 yuan/㎡ | 32,000 yuan/㎡ | -28.9% |
5. Suggestions on the “golden balance point” for building age
Based on comprehensive market data, it is recommended to give priority toBuilding age 8-15 yearsReal estate: It avoids the premium of new houses while retaining sufficient loan space. At the same time, the community facilities are mature. If you buy an old house, you need to pay attention to:
- Whether to be included in the old renovation plan
- Whether school district qualifications are restricted by the age of the building (some cities stipulate that a degree requires "the age of the building ≤ 20 years")
-Have any important facilities (such as circuits, waterproofing) been replaced recently?
Conclusion
The age of a building is not an absolute measure of value and needs to be judged comprehensively based on the location, policies, and building maintenance conditions. The recently hotly discussed "urban renewal" policy has brought new opportunities to some old houses. It is recommended that home buyers make dynamic evaluations and seize the low value areas.
