How should I compare two properties as potential investments?

Use a common comparison basis

Write down your investment aims, time horizon, household constraints and minimum liquidity needs before comparing homes. For each property, collect equivalent information on condition, documentation, access, services, intended use, management needs and expected availability. Label each claim by source and verification status. Differences in location or design may make direct comparisons imperfect; explain those differences rather than hiding them in a single score.

Compare full scenarios

Use matching assumptions for financing, operating periods, personal use and currency wherever possible. List purchase and ongoing cost categories, including repairs, management, insurance, utilities and periods without rental activity. Separate confirmed costs from estimates and request property-specific evidence. Compare rental histories with forecasts carefully and identify permissions or legal issues that could affect use. Model less favourable cases and consider the consequences if income is delayed, costs rise or a sale is not convenient.

A qualified financial adviser can assess suitability and concentration within your wider finances. Ask an accountant about tax and reporting in relevant jurisdictions, a Greek lawyer about title and contractual matters, and an independent engineer about condition and documentation. Include a “neither” option and record which unanswered questions would change your choice. Avoid selecting solely by projected income, marketing claims or a scoring total that conceals uncertainty.
