Compare equivalent homes and change the holding period before drawing a conclusion.
Use the Rent vs Buy alongside this illustrative example.
A practical example
Run the same purchase and rental assumptions for a short stay and for a longer stay. Upfront buying costs have much less time to be spread out in the short scenario. Keep property quality and location comparable so a cheaper rent does not merely represent a different home.
Check the result
Record assumptions for maintenance, taxes, rent growth and property appreciation. Repeat with lower appreciation instead of treating an optimistic property-value increase as guaranteed.
Try a comparison
Run a scenario with an unexpected maintenance expense while keeping the rental assumption unchanged. Observe whether the relative outcome changes over your intended stay. A decision that depends on every optimistic assumption deserves closer examination of the actual local costs.
What this does not establish
The comparison cannot price flexibility, job changes or security of tenure. Its result is not investment advice and depends heavily on assumptions you supply.
