This article will combine the hot topics and hot content on the Internet in the past 10 days, analyze in detail the calculation method and influencing factors of second-hand housing loan amount, and provide structured data for reference.
1. Main factors affecting the amount of second-hand housing loans

The determination of the second-hand housing loan amount is affected by many factors. The following are the core factors:
| factors | Description |
|---|---|
| house appraisal price | The bank will determine the loan base based on the valuation of the house by a professional appraisal agency, which is usually 70%-80% of the appraisal price. |
| home buyer income | The monthly income must cover more than twice the monthly payment, otherwise the loan limit may be reduced. |
| Credit record | A good credit record can improve the loan approval rate, while overdue loans or excessive debt may reduce the amount. |
| Loan term | The longer the loan term, the smaller the monthly payment pressure, but the total interest cost is higher. |
| down payment ratio | The higher the down payment ratio, the lower the loan amount, and vice versa. |
2. Calculation method of second-hand housing loan amount
The calculation of the loan amount is usually based on the following formula:
Loan amount = appraised value of the house × loan-to-value ratio - down payment
For example, if the appraised value of the house is 3 million yuan, the loan ratio is 70%, and the down payment is 900,000 yuan, the loan amount is:
| calculated item | numerical value |
|---|---|
| house appraisal price | 3 million yuan |
| Loan ratio | 70% |
| down payment | 900,000 yuan |
| Loan amount | 3 million × 70% - 900,000 = 1.2 million yuan |
