Have you received an offer to invest in overseas real estate? Were you told about impressive returns, potential for appreciation, and attractive rental income? Now is the time to move from promises to numbers.
Between the salesperson’s flashy presentation and the actual return you’ll see in your bank account, there’s a gap created by costs that are sometimes “overlooked” along the way: purchase tax, attorneys’ and notaries’ fees, management fees, taxes on rental income, ongoing maintenance expenses, and periods when the apartment stands vacant.
The return calculator below is designed to give you a realistic and transparent picture of the expected return— gross and net, before and after taxes—while taking into account all relevant expenses and taxes. This will allow you to make an informed decision based on your realistic estimates.
How Does a Real Estate Calculator Work? The Factors That Determine the Actual Return
To get an accurate picture of the expected return on a real estate investment, you need to enter several key parameters into the return calculator.
First, the purchase price of the property—this is the basis for all calculations.
However, the purchase price alone is not enough: you must add the associated purchase costs, which include attorney fees, purchase tax, registration fees, appraisals, and brokerage fees. These costs can amount to the transaction price and, in some cases, even more, and directly affect the final return.
In addition, the costs of renovation and furnishings (if required) must be included in the cost calculation. Depending on the equity and the level of leverage, financing costs must also be calculated.
In addition to one-time costs, you need to consider the expected annual income. This is where the expected monthly rent and the annual occupancy rate come into play—that is, the percentage of the year the apartment will actually be rented out (usually less than 100%). Multiplying these two parameters will give you the actual annual income. The type of lease (short-term/long-term) affects maintenance costs, the occupancy rate, and, consequently, the income rate.
From this income, you must deduct the following fixed annual expenses: property management and building maintenance fees, building and contents insurance, annual property tax (in accordance with the state’s tax policy), and ongoing maintenance costs. Finally, it is important to enter the tax rate on rental income, which is calculated according to local tax policy.
The result? The calculator will show you several key figures: net cash flow, principal repayment, appreciation, total profit, net return, return on investment, total expenses, and more.
Real Estate Return Calculator
The return on overseas real estate is one of the key indicators for assessing an investment’s profitability, and it is calculated in several stages to provide a complete picture—from the initial review to a detailed analysis that includes expenses and risks.

Calculating Gross Rental Yield – Real Estate Calculator
Gross rental yield is the simplest and quickest calculation, providing an initial picture of the income potential before any expenses. To calculate it, real estate investors use the apartment’s price, excluding closing costs and furniture. The total cost includes not only the purchase price but also purchase tax, brokerage fees, notary fees, initial renovations, and startup costs such as setting up a company if required. The result is then multiplied by 100 to obtain a percentage. For example, if a property costs €200,000 including all associated costs, and the monthly rent is €1,000, then the annual rent amounts to €12,000, and the gross yield is 6%. This calculation is useful for an initial market assessment, such as comparing cities or similar properties, but it ignores ongoing expenses like maintenance or property taxes, so it can be misleading if you don’t proceed to the next step.
Calculating the Net Yield (Cap Rate)
Net yield, also known as the cap rate, provides a more realistic picture because it deducts all annual operating expenses. Start again with the annual rent, but this time multiply it by a realistic occupancy rate based on the type of lease and the property’s location—for example, 90% or 92% to account for periods without tenants. Then we subtract expenses such as local property tax, property tax, property insurance, day-to-day management (if renting through a company), routine maintenance, initial furnishing costs, advertising an empty apartment, and a reserve for major repairs. The result is divided by the total investment and multiplied by 100. In the same example of the property with a total investment of €210,000, an annual income of €12,000, and expenses of €2,000, the net yield drops to 4.76%. This metric is particularly important for comparing properties because it focuses on net operating income (NOI) relative to the property’s value, and is also used by banks and institutional investors to assess property values.
Cash-on-Cash Return for Leveraged Investments
If you use financing such as a mortgage, the most relevant return is the Cash-on-Cash Return, which measures profitability based solely on your equity. Here, you take the annual net cash flow—that is, NOI minus annual mortgage payments (monthly payment multiplied by 12)—and divide it by the equity invested, such as a 25–30% down payment on the property price and transaction costs out of your own pocket. For example, if you invested €60,000 in equity, and the net cash flow after the mortgage is €4,000 per year, the return is approximately 6.67%. This metric is critical for private investors abroad because it shows how much real money goes into your pocket each year relative to the capital risk, and takes into account the mortgage interest rate and local market conditions.
Cash-on-Cash Return: The true return on equity in a leveraged investment
How to calculate
Annual NOI
Rental income minus property operating expenses.
Mortgage payments
12 monthly payments, including interest.
Net cash flow
NOI minus annual mortgage payments.
Equity
Down payment and transaction costs paid by the investor.
Cash-on-Cash
Return on equity only.
Example
Equity: €60,000 · Annual net cash flow: €4,000 → Cash-on-cash yield ≈ 6.67%
What is considered a good return in the international real estate market and a good return in the Israeli real estate market?
A "good" return depends on location, property type, and risk, but there are general benchmarks based on global market data. In stable, developed countries such as the U.S., the U.K., Spain, or the Netherlands, a gross yield of 5–7% is considered reasonable, while a net yield of 3–4.5% is good and covers risks such as currency volatility or regulatory changes. In more expensive markets such as Germany, France, or Switzerland, yields are lower—2.5–4.5% gross—but are offset by long-term appreciation.
A rule of thumb for Israeli investors: A net yield of over 5% in a stable major city is considered excellent, while 4% is a reasonable figure if there is potential for appreciation; a yield of over 8% (on long-term leases) may indicate risks such as enforcement issues or dependence on a weak local market.
The average gross return in Israel in 2026 is approximately 2.5–3.5% nationwide, with a net return of 2–3% after expenses. A return of 3–4% is considered good in the center of the country, and 4–5% is considered excellent in the periphery.
It is important to note that in the popular destinations for overseas real estate investment among Israelis—Greece, Cyprus, Portugal, the U.S., Poland, and more recently Dubai—there is significant variation between geographic regions, property types, appreciation potential, old versus new properties, and many other factors. Be sure to enter all known details into the calculator and compare offers as accurately as possible.
Advanced profitability metrics: ROI, IRR
To assess long-term viability, metrics are used that take into account the entire investment period. ROI (Return on Investment) calculates the total profit—cumulative rental income plus capital gains from the sale, minus all expenses and taxes—divided by the total investment, and multiplied by 100. This metric is good for short-term investments, but it does not take time into account.
IRR (Internal Rate of Return) calculates the average annual rate of return over a 5- to 10-year period by discounting annual cash flows, including the final sale. An IRR higher than 10–12% is considered good in stable markets.
Tax on Rental Income in Greece (2026)
According to the updates for 2026, Greece is introducing a new progressive tax rate for rental income, with an intermediate rate of 25% for income between €12,001 and €24,000.

What does this mean for investors?
As rental income increases, the marginal tax rate rises, so it is important to calculate the net after-tax return.
Purchase Tax and Related Costs in Greece
Property Transfer Tax
- Standard purchase tax: 3% of the property’s “tax value” (the higher of the contract price and the objective value), plus a 3% municipal surcharge on the tax, resulting in an effective rate of 3.09%.
- 3.09% applies to most apartments classified as “standard” that are not subject to VAT.
VAT Exemption/Suspension for New Apartments
According to the updates through 2026, the government is extending the VAT exemption/freeze on the sale of new apartments (24%) so that, for most new-construction transactions, the buyer pays only 3% purchase tax and no VAT, at least through the end of 2026.
This update results in significant cost savings on the purchase of new projects compared to the old model of 24% VAT on the sale price.
Additional expenses when purchasing property in Greece
- Attorney's fees: Typically around 0.8%–1.2% of the transaction value + 24% VAT.
- Notary fees: Typically 0.8%–1.5% of the property value plus VAT, depending on the scope and number of documents.
- Registration fees / Land Registry / Cadastre: Approximately 0.5%–0.7% of the property value.
- Brokerage fees (if applicable): Typically 2%plus VAT paid by the buyer, as agreed with the broker.
- Engineering inspections / Engineer / Appraiser: One-time cost (300–800 euros for a standard apartment in practice; in most residential transactions in Athens, total purchase costs—including purchase tax, attorney fees, notary fees, registration fees, and brokerage fees—range from 6% to 8% of the transaction price, and it is important to include them in the yield calculation.)
