Purchase type

Single property or Scottish portfolio

Purchase

Required basics + optional cost detail

Borrowing (Purchase)

Deposit + mortgage + monthly finance cost

Interest-only uses (loan + arrangement fee) × rate ÷ 12. Repayment uses standard amortisation on (loan + arrangement fee).

Buy-to-let (BTL)

Rent + running costs + yields
Operating-cost breakdown (optional)

If you fill any of these in, they are added together with voids and bad-debt allowances and replace the single "Monthly running costs" figure above (no double counting). Letting fees stay in the letting fee field.

BTL Refinance (BRR)

Cash-out + money left in + ROI

Net cash released: refi loan − debt repaid (original mortgage including any financed fee, or the full bridge redemption balance including rolled-up interest and exit fees) − any refinance fees and costs taken from the proceeds. Gross borrowing is not cash released. Money left in: total cash invested − net cash released. If money left in is negative, you've pulled out more cash than you originally put in.
