Or Flip It Move Into the Flat and Lease the House
Feeling weighed down by a large home with rooms nobody uses? Consider the reverse approach: downsize into a brand-new, purpose-built granny flat and lease the main house to tenants.
You benefit from a modern, energy-efficient dwelling with lower running costs and minimal upkeep — while the rental income from the larger property covers far more than a granny flat mortgage ever would.
Smaller home. Smaller bills. Bigger income.
