The difference between a mortgage and an installment plan when buying an apartment

The main difference
The main difference between a mortgage and an installment plan lies in the source of financing and the payment structure:
- with a mortgage, the bank provides the money and you repay it with interest;
- with an installment plan, payments are made directly to the developer in stages.

1. Payment term

A mortgage usually runs for 10 to 25 years.
An installment plan is usually much shorter, more often 1 to 3 years and sometimes up to 5.
That directly affects the size of the monthly payment.

2. Total overpayment

A mortgage includes interest, so the total overpayment can be substantial.
An installment plan is often interest-free or has only a minimal markup.
From the perspective of total cost, an installment plan is often more beneficial, but not for every buyer.

3. Monthly burden

Because the mortgage term is longer, the monthly payment is usually lower.
With an installment plan, the term is shorter, so the monthly burden is higher.
This option requires a stronger and more stable cash flow from the buyer.

4. Buyer requirements

A mortgage usually requires income verification, credit history, and official employment.
An installment plan is often easier to obtain and may not require proof of income.

5. Where it can be used

A mortgage can be used for both new developments and the secondary market.
An installment plan is usually available mainly in new developments and directly from the developer.

6. Ownership rights

With a mortgage, the apartment is usually registered in the buyer’s name immediately, although it remains pledged to the bank.
With an installment plan, ownership often transfers only after full payment.
This is an important legal distinction.

7. Flexibility of terms

Mortgage terms are mostly fixed by the bank.
Installment plan terms may sometimes be discussed with the developer.

Conclusion

If a lower monthly payment matters most, a mortgage is usually the better choice.
If minimizing overpayment is the priority, an installment plan can be stronger.
If it is difficult to confirm official income, installment plans are often more practical in real life.
The right choice always depends on income, timeline, and your tolerance for financial pressure.
