Fit Out Calculator
Estimate fit-out budget, rent uplift, added value, ROI, and break-even timing.
Valuation assumptions & building age
Israeli residential gross yields average ~3.15% nationally (Tel Aviv ~2.6%, Jerusalem ~3.1–3.3%), so 3.2% is a realistic cap-rate default. Older buildings often surface plumbing/electric surprises — hence the surcharge toggle. Structural or layout changes may need a permit (heter bniya); cosmetic work usually does not.
For planning only — not a loan, tax, or legal offer. Israeli property, mortgage, tax, and bank rules vary by buyer profile and deal structure.
Is that renovation actually worth the money? If you own commercial property in Israel, you probably ask that often. A high-quality fit-out attracts better tenants and lets you charge higher rent, but revenue is vanity, profit is sanity, and yield is reality.
Most investors only weigh the construction cost against the rent increase and miss the bigger picture: asset valuation. Because of how cap rates work, a small rise in rent can produce a large jump in the property’s total value. This calculator runs those numbers for you, so you can see the value you create, your break-even point, and your true ROI before you commit.
How to read your results
Once you have run the numbers, three figures matter most.
1. The cap-rate multiplier
This is the most important number on the screen. Commercial property is valued on the income it produces, so every shekel of extra annual rent is divided by your cap rate. In an 8% cap-rate market, every 1 NIS of added annual rent lifts the property value by roughly 12.5 NIS. That is how a fit-out builds equity even when the monthly cash flow looks modest.
2. Amortised cost vs rent uplift
This is your sanity check. Rent uplift is the extra rent the tenant pays because of the work; amortised cost is the fit-out spread across the lease term. For the deal to make sense, the rent uplift should be clearly higher than the amortised cost. If the two are close, you are funding the tenant’s renovation for free.
3. The break-even point
This shows how long it takes to earn back the cash you put in. In commercial real estate a break-even under 24 months is strong. If it runs longer than half the remaining lease, the risk rises sharply.
The bottom line
Do not build for the sake of building. Use these figures to confirm that every shekel you spend on the fit-out comes back to you as equity in the building. When you are ready to pressure-test a real deal, talk to the Semerenko Group team.
