Helsinki new-build at €1,122,000 and €5,002 monthly rent: does the net yield work?

A first look at financing sensitivity has raised a harder question: how much room is there for vacancy or higher building costs before this stops being worthwhile?

The Helsinki property is a 4-bed new-build flat priced at €1,122,000, with projected rent of €5,002 per month. That is around 5.3% gross. I have budgeted for management, ordinary upkeep, empty periods, insurance and a maintenance reserve, but I do not yet understand the full flow of property tax and housing-company charges.

The rent assumption is therefore only useful if it is supported by comparable signed rents and if I know what it includes. I am also testing higher financing costs rather than relying on one rate. Which would you resolve first: the achievable rent and likely vacancy, or the building-level charges that cannot easily be changed after purchase? What net return would leave enough margin for the remaining uncertainty?

The gross calculation is fine: €60,024 annual rent against €1,122,000 is about 5.35%. I would concentrate on the housing company’s charges rather than property tax in isolation. Establish exactly what the monthly charge covers, whether the land is owned or leased, and whether any company financing creates a separate charge. Also, is €5,002 supported by comparable signed rents or just the asking estimate?

Tenant turnover could move the result more than a modest error in property tax. One vacant month cuts annual rent to €55,022, or about 4.9% gross before any other expense. At this rent level, I’d want to know the likely tenant group and whether €5,002 includes utilities, parking or furnishings.

I’m not convinced turnover should automatically be treated as the main danger; a suitable tenant for a larger flat may stay longer. The missing fact is financing. Are you judging this as an unleveraged purchase, or will there be a mortgage? A deal that produces an acceptable property-level net yield can still have weak cash flow if borrowing costs reset higher. I’d calculate the net yield before financing first, then stress the actual debt separately.

There isn’t one net-yield threshold that fits everyone, but the decision can be made less subjective. Get the housing company budget and full fee schedule, clarify land ownership, insurance responsibilities and how property tax reaches the owner, then rebuild the model from those figures. Run at least three rent and vacancy cases rather than relying on €5,002 throughout. Finally, compare the stressed net income with both your financing cost and a lower-effort alternative for the same €1,122,000.
