One more point: how will the five bedrooms be let—under one lease for the whole condo or room by room? The second approach might change the rent potential, but it also changes turnover, vacancy patterns, management effort and wear. The current €739 figure needs to match the actual rental...
Is €739 supported by an existing tenancy, or is it an asking-rent estimate? That distinction matters more than fine-tuning the maintenance reserve. I’d also want the current condominium fee and clarification on whether water, parking or other building costs are included in that rent figure.
