How long does it take to move a portfolio across?

Plan an afternoon, not a week. Each property takes a few minutes: address, tenancy, rent schedule. Bank accounts link once through Open Banking and cover every property paid into them, and certificates you upload are read by Magic Upload and turned into renewal reminders automatically. There is no template to fill in and nothing to import by hand. Most landlords add their busiest properties first, watch a week of rent match itself, then bring the rest across.
