LTV Calculator: Loan-to-Value Explained

1. Short answer

LTV (loan-to-value) is the outstanding loan divided by the property's value, as a percentage. It says what share of the property was paid for with borrowed money.

LTV = (loan amount ÷ property value) × 100%

A € 199,500 loan on a € 285,000 property gives an LTV of 70%. Watch the denominator: that is value, not your total investment. This makes LTV fundamentally different from gross and net yield, which do use total investment.

2. What LTV is — and what it is not

LTV is a risk measure, not a return measure. It says nothing about what a property earns; it says how much buffer sits between the loan and the value. For a lender that is the central question: in a forced sale, the proceeds must cover the loan.

Two things that are often conflated:

3. The formula, component by component

Numerator — outstanding loan. All loan parts together, not just the largest. A second or subordinated loan counts: the lender looks at total debt secured on the property.

Denominator — value. Which value depends on who is asking:

Value basis When it is used
Purchase price At acquisition, absent a more recent appraisal
Market value in let condition What lenders normally use for rental property
Market value with vacant possession Owner-occupation, or sale after tenant departure

Those three can differ substantially on the same property. Always ask which value an LTV is based on before comparing two offers.

4. Worked example

The same apartment as on the other pages: bought for € 285,000, with € 44,740 of transfer tax and acquisition costs, financed with € 199,500.

Item Amount
Purchase price (= value at acquisition) € 285,000
Loan amount € 199,500
Acquisition costs (not financed) € 44,740
Total investment € 329,740
Own equity € 130,240

LTV = (199,500 ÷ 285,000) × 100% = 70.0%

Metric Value What it means
LTV 70.0% Seventy percent of value is borrowed
Equity as a share of investment 39.5% What you actually put in
Difference 9.5 points The acquisition costs the lender does not finance

Anyone hearing "70% LTV" and assuming they contribute 30% will be € 44,740 short on this property. That is not a detail when planning your equity.

5. How LTV changes over time

LTV is not fixed. It falls with amortisation and with rising value, and rises when value falls. The same property after five years on a 5% annuity loan:

Scenario Outstanding Value LTV
At purchase € 199,500 € 285,000 70.0%
After 5 years, value flat € 183,200 € 285,000 64.3%
After 5 years, value +2% a year € 183,200 € 314,663 58.2%
After 5 years, interest-only, value flat € 199,500 € 285,000 70.0%

That last row is the argument against interest-only that is rarely made explicitly: your LTV then moves only with the market, never with your own effort.

6. What counts as a good LTV?

Range What it usually signals
below 60% Low risk premium, comfortable financing margin
60% – 70% Standard for Dutch rental property
70% – 80% Higher rate premium; not every lender will go here
above 80% Rarely available for investment property

A low LTV reduces your rate and your risk, but also your return on equity: you commit more of your own money for the same rental income. LTV is a trade-off between risk and leverage, not a number to minimise.

7. Three mistakes that distort the number

Using vacant-possession value on a let property. That makes LTV look lower than the lender calculates, and can derail a financing application unexpectedly.

Counting only the main loan. A second loan part belongs in the numerator. The lender looks at total debt on the security.

Confusing LTV with leverage. Leverage is measured against total investment, not value. In the example above LTV is 70% while equity is 39.5% of the investment — those two do not add up to 100.

8. Frequently asked questions

Will a lender finance the transfer tax?

Usually not for investment property. LTV is calculated on value, and acquisition costs fall outside it. Expect your own contribution to be higher than "100% minus the LTV" suggests.

What is the difference between LTV and LTC?

LTV compares the loan to value; LTC (loan-to-cost) compares it to the total project cost. On a conversion or renovation these diverge sharply: cost is what you put in, value is what it is worth afterwards.

Does my LTV change when the market rises?

Yes, it falls. With a flat loan and rising value the ratio improves. That can justify asking for a lower risk premium at a rate review — though most lenders will want a fresh appraisal first.

Why is the lender's value lower than I expected?

Rental property is appraised in let condition. A sitting tenant limits what a buyer can do, which depresses value relative to the same property without a tenant. How much varies by property, tenancy and market segment; ask the appraiser for the reasoning rather than applying a rule of thumb.

Does a renovation count towards value?

Only once carried out and appraised. Some lenders will finance against post-works value, but with a construction escrow and staged inspections. Base your application on current value unless you have that commitment in writing.
