A konut kredisi installment is not price divided by months. It is principal, rate, compulsory insurance, and a cap set by ekspertiz, not the asking price.
This is general information for English-speaking buyers, not a loan offer and not legal or title advice. Confirm the current product sheet, LTV cap, and insurance list with the lender before you sign anything.
The number on the sheet is not the listing price
Sellers quote a price. Banks lend against an appraisal (ekspertiz) and a loan-to-value (LTV) cap. If the ekspertiz comes in below the agreed price, you still owe the seller the gap in cash. The installment is calculated on the approved principal, not on the brochure.
That is the first failure mode foreigners hit: they divide the asking price by 120 or 180 months, then discover the bank will only finance a smaller figure. The monthly payment they planned was fiction.
For how the wider file is assembled (documents, registry, disbursement), read our konut kredisi overview. This article stays on one job: how the monthly amount is built.
What actually goes into an installment
A typical Turkish home-loan installment is an amortizing payment: part principal, part interest, on a fixed schedule for that product. On top of that, many banks collect insurance premiums in the same monthly debit, or they require you to keep policies current as a condition of the loan.
Ask the branch to split the figure in writing:
- Principal plus interest (the amortizing piece)
- Building / fire insurance if the bank bundles it
- Life insurance if the product requires it
- Anything else that will hit the same account (account fees are separate; do not assume they are inside the installment)
DASK (compulsory earthquake insurance) is usually a policy you must hold for the property. It is not always baked into the installment the way life cover is. Treat it as a cash cost you still have to pay, even if the amortization table looks clean.
Principal is capped twice
Two ceilings sit on the loan amount:
- Your affordability ceiling. The bank looks at documented income versus existing debts. Foreign income is only useful if that branch already knows how to verify it.
- The property ceiling. LTV is applied to the ekspertiz value (or the purchase price, whichever rule the product uses), not to what you hope the home is worth.
Illustrative example, not a market quote: you agree 4,000,000 TL. The ekspertiz comes in at 3,600,000 TL. If the product’s maximum LTV is 80 percent of appraisal, the bank’s principal cap is 2,880,000 TL. You fund 1,120,000 TL plus fees, not a neat 20 percent of the asking price. The installment is then calculated on 2,880,000 TL, not 4,000,000 TL.
Do not treat any percentage in this paragraph as the rule in force today. Caps change with regulation and with the bank.
Rate, term, and why “small” differences compound
The advertised rate is not a trivia number. Over 10 to 15 years it dominates total cash out. A longer term lowers the monthly debit and raises total interest. A shorter term does the opposite.
Illustrative only: on a 2,000,000 TL principal, stretching from 8 years to 12 years can drop the monthly amortizing piece by a noticeable amount while adding years of interest. The “affordable” installment is often the more expensive loan in total. If the branch shows you only the monthly figure, ask for total repayment on the same sheet.
Fixed versus variable matters for planning. If the product can reprice, the installment you start with is not a promise for year seven. Read the contract clause, not the campaign landing page.
Fees that never appear in a web calculator
File fees (dosya masrafı), ekspertiz fees, and land-registry costs for the ipotek are usually paid up front or deducted at disbursement. They do not vanish because the amortization table looks round.
Some buyers mentally “spread” those fees across months and then forget them. That is how a file that looked fine on a phone calculator becomes a cash crunch in the week of tapu transfer.
Insurance is the other silent add-on. Life cover sized to the outstanding principal, plus building cover the bank accepts, can add a second line to the monthly debit. If you earn in a foreign currency and the premium is in TL, a weak lira month hits you twice: the installment and the premium.
How banks check that you can actually pay it
The installment is not approved because you say it fits. The desk runs a ratio: proposed installment plus existing loan and card minimums, versus documented net income. High revolving use on Turkish cards, or several consumer loans, can kill a file even when the property looks clean.
If your income is paid abroad, the branch may haircut it, ignore bonuses, or refuse the product. That is not a moral judgment. It is an operations problem: they need a format their system already knows.
Early repayment and the installment you think you will “just pay extra”
Many konut kredisi contracts allow partial or full early repayment with a fee defined in the agreement. Do not assume you can overpay freely the way some other countries allow. If your plan is “I will smash the principal when I get a bonus,” read the early-pay clause before you size the loan around that hope.
Missed payments are not a polite reminder cycle. The ipotek is the bank’s security. Persistent default can lead to enforcement against the property. Budget a buffer in the same currency as the installment.
What to demand on the written offer
Before you treat a monthly number as real, get a sheet that states:
- Approved principal (after LTV and ekspertiz, even if still estimated)
- Rate type (fixed or variable) and the installment of principal plus interest
- Compulsory insurance list (DASK, building, life) and whether premiums are collected with the installment
- File, appraisal, and registry costs as separate lines
- Early repayment rules
- What happens if ekspertiz is below the purchase price
If the branch will not put those lines on paper, you do not have an installment. You have a conversation.

Before you apply
Ask how the installment is split (amortization versus insurance), what the ekspertiz costs, and what you pay in cash if appraisal comes in below the agreed price. If you are not a Turkish citizen, confirm the branch can board your ID and income type before you pay a large deposit.
