Completely passive income is too strict a requirement and realistic only for the wealthy. A minimal amount of /legwork/ is usually unavoidable and acceptable to the retail investors:

• cross-border fund transfer
• tax filing
• currency conversion
• monitor a stock position in order to receive dividends.
• /keeping tabs/ of passive income accounting

Now, one level above these effort, some inactive management effort may be required, but some laid-back investors will refuse to put in such simple efforts like:

• maintaining the relationship with the local agent. Is she reliable and diligent?
• property maintenance
• monitor market trends, make long term, gradual adjustments to fend off competition and stay relevant. Gradual adjustment is less stressful.
• Avichal suggested another form of inactive management —

Form a partnership with a trusted local agent and run it like a business. Perhaps like airbnb. He feels such a business could grow.

Perhaps you could find gainful employment to keep yourself engaged and helpful to your customers and other people. Better than passively collecting rent.
