What you will learn
For most Iranian households a home is both a shelter and their single largest asset. In this lesson we look at a house through the lens of an asset and learn how its price is expressed (price per square meter), how you can earn income from it instead of selling (deposit and rent), what hidden costs every transaction carries (commission, tax, and fees), and why housing prices in Iran usually move in "sudden jumps followed by long lulls" rather than a smooth, steady climb. Every number here is hypothetical and for teaching, except where a date and source are given.
Definitions
Real asset: an asset that is itself a physical, usable good, such as a house or land, as opposed to a financial asset like a stock or a bank deposit. Housing is a real asset.
Price per square meter: the price of one square meter of residential floor area. The total value of a unit is roughly: total value ≈ price per square meter × area. It varies with district, building age, floor, build quality, and amenities.
Deposit (rahn): a sum the tenant hands the owner at the start of the lease and gets back at the end. Rent (ejareh) is the monthly amount the tenant pays. In a full deposit (rahn-e kamel) arrangement the monthly rent is zero and everything is paid as a deposit.
Transaction cost: every sum of money and amount of time that buying or selling an asset takes from you, separate from the price itself: agent commission, tax, municipal fees, and registration costs.
Mechanism 1: how a home's price is expressed
Unlike a gold coin or a dollar, which each have a single daily price, every house is unique. So the market uses a common language: price per square meter. When an "average price per square meter" for a district is announced, it means the district's transactions were summed and divided by total area. Note that this is only an average: within the same district, a brand-new unit and a teardown can differ several-fold per square meter. Price per square meter is good for broad comparison, but it does not replace inspecting and appraising each unit.
Mechanism 2: how deposit and rent convert into each other
Owner and tenant can shift the mix of deposit and rent: a larger deposit for lower rent, or the reverse. The rate that converts the two is called the "conversion rate," and it is a market custom, not a fixed legal number; it rises and falls with bank deposit rates and inflation.
Hypothetical example: suppose the customary conversion rate is 3 percent per month. Then every 100 million tomans of deposit is roughly equal to 3 million tomans of monthly rent. So if an owner asks for "200 million deposit and 5 million rent," a tenant with cash could offer to eliminate the 5 million rent by adding about 167 million tomans more to the deposit. This is only a teaching calculation; the real rate is agreed between the parties.
Worked example: the true cost of a purchase (hypothetical)
Suppose you buy a 75-square-meter apartment at a hypothetical price of 100 million tomans per square meter. The total value is 7,500 million tomans, that is 7.5 billion tomans. Now set the transaction costs beside the price:
- Agent commission (buyer's share): per the tariff, 0.5 percent on the first 500 million tomans and 0.25 percent on the excess. That is (500 × 0.5%) + (7,000 × 0.25%) = about 20 million tomans, plus value-added tax. The seller pays a similar amount separately.
- Property transfer tax: 5 percent, but not on the market price; on the "assessed value (arzesh-e moamelati)" set by the Tax Administration, which is usually far below the real price. If this unit's assessed value were, say, 500 million tomans, the tax would be 25 million tomans (paid by the seller).
- Side costs: registration and notary fees, and settling municipal and tax dues that must be cleared before the deed is transferred.
The lesson of this example is clear: the price in the listing is not the last figure that leaves your pocket.
In the Iranian market
The commission tariff is set by the Real Estate Brokers' Union (Ettehadiyeh-ye Moshaveran-e Amlak). For sales, it is that 0.5 percent up to the cap and 0.25 percent on the excess, charged separately to each party. For rentals, the common custom is 25 percent (one quarter) of one month's rent from each party. Value-added tax is added on top of all these commissions.
The tax on the outright transfer of real estate is set out in Article 59 of the Direct Taxes Law: 5 percent of the assessed value for transferring the property, and 2 percent for transferring a business-location right (sarqofli). Because the base of this tax is the "assessed value" rather than the day's price, the tax burden of buying and selling housing in Iran is, in practice, light; this is one reason a home carries a low tax-holding cost alongside its potential gain.
The "jump and lull" pattern. Nominal housing prices in Iran usually do not rise steadily; during currency-shock and high-inflation episodes (for example the years 2011 to 2013, 2018, and 2020 to 2021) prices multiply within a short window, and then enter a recession and a "nominal lull" in which the toman price stays roughly flat while general inflation slowly erodes its real value. Rents behave more smoothly: per the Statistical Center of Iran, the year-on-year rent inflation in Khordad 1405 (June 2026) was about 31.2 percent, well below general inflation that month. The reason is that rent is reined in by a household's monthly ability to pay, not by expectations of a price jump.
Common mistakes
- "Housing always makes a profit, for everyone." In a lull, the toman price is flat but the real value (after subtracting inflation) can fall. Real return must be measured against inflation, not by the toman figure alone.
- Confusing nominal and real prices. A home price doubling in a year when inflation was also high does not necessarily mean "getting richer." To understand this difference, see the lesson What is inflation.
- Ignoring transaction cost and low liquidity. Selling a house takes months and eats a percentage of the money as transaction cost; this differs from quickly selling gold or a stock. The lesson Liquidity unpacks that difference.
- Treating "assessed value" as "market price." The base of the transfer tax is the official assessed value, not the price that actually changes hands; the two should not be swapped.
Summary
Housing is a real asset whose price we express through "price per square meter," from which we earn income through "deposit and rent," and in every transaction we must count the "transaction cost" (commission, tax, and fees) separately from the price. In Iran its price behaves in a jump-and-lull pattern rather than a steady climb, and to judge it correctly you must measure return against inflation and alongside its low liquidity. In the previous lesson on liquidity we saw why turning a home into cash is slow and costly; that very feature sets housing apart from other assets. For an overview of the household's asset map, see the lesson What is an asset and the Sahmino Academy series.
