Rent or buy an office? How to decide right
Price-to-rent ratio, mortgage repayment versus rent, equity and transaction costs: a structured decision framework for a business weighing whether to buy its office.
The question worth millions
A stable business paying high rent for years sooner or later asks itself: why not buy? The right answer depends on the numbers — not on the feeling that paying rent "throws money away".
Three central figures: the property's price-to-rent ratio, the expected monthly return on financing, and the equity the purchase locks up.
Price-to-rent ratio: the first compass
Divide the property price by the annual rent it would generate. The result — how many years of rent "buy" the property. A ratio below 15 suggests the purchase is relatively cheap; a ratio above 20 says the rental market is more attractive.
In Israel, quality commercial real estate in the centre typically trades at a ratio around 12–18 — depending on city, property age and tenant quality in the area. The ratio for any specific property can be calculated in seconds using Walz's calculator.
Monthly payment versus monthly rent
A commercial mortgage is typically available up to 60%–70% of property value — meaning 30%–40% equity is required. Compare the monthly mortgage payment to the rent you would pay: a payment below rent — first sign the purchase makes sense.
But this is only a partial comparison: the payment includes a principal component that builds equity, whereas rent is net expense. On the other hand, ownership carries costs the renter doesn't know — structural maintenance, building insurance, and periods of vacancy.
Transaction costs that add 8%–10%
Purchase tax on a commercial property in Israel is 6% of price — flat, no brackets. Plus legal fees (customary 0.5%–1% plus VAT), brokerage if applicable (1%–2% plus VAT), appraisal, due diligence and fees.
In practice, the true cost of entry into a transaction is about 8%–10% of property price. Walz's transaction cost calculator does the full breakdown.
What the equity could have done instead
Equity of 30%–40% of property price is capital that could serve the business for growth: inventory, recruitment, marketing, development. The opportunity cost of this capital is part of the calculation — especially for young businesses with high returns on internal capital.
The practical rule: purchase suits a mature business with stable cash flow, a long horizon in the current location, and spare capital not needed for growth. A rapidly growing business almost always benefits more from the flexibility of rent.
And what about VAT?
VAT at 18% applies to the purchase of a commercial property by an active business. An eligible business recovers it as input tax in most cases, so the cash-flow effect is temporary — but needs to be planned upfront, as it's a large sum paid at transaction time.
Bottom line: a correct calculation compares total cost of ownership (mortgage repayment, maintenance, tax, insurance, cost of capital) against total rent cost — not just "mortgage versus rent."
