Here is a a ballpark estimate, based on my simple model...

Assumptions for ownership cost calculation

down_payment_rate = 0.20 # 20% down payment
loan_term_years = 25 # Common Finnish mortgage term
interest_rate = 0.014 # 1.4% (projected 12-month Euribor 2025 + 0% margin for simplicity)
maintenance_fee = 4.60 # €/m²/month (national average,)
apartment_size = 79 # m² (average 2-bedroom,)
insurance_cost = 100 / 12 # €100/year for 40 m², scaled to 79 m² ≈ €200/year ()
property_tax_rate = 0.0093 # Lower bound for residential buildings ()
repair_cost = 20 # €/month estimate for minor repairs
incidental_cost = 10 # €/month for miscellaneous

PS: This is better sorted
