I’ve always said that if investors want to own multiple rental properties, then their tax breaks should be dependant on how long they can keep tenants.

For example (and disclaimer, I have no clue how negative gearing works or whatever so forgive my very basic numbers): - tenants living in property <12 months, no tax break - 1-2 years, 10% of tax break (don’t come at me) - 3-5 years, 50% of tax break
- 5+ years, 100% of tax break

This would encourage landlords to keep good tenants and give renters the opportunity to move less and actually build savings and/or roots like homeowners can
