For flips, developments, holiday lets and the tax at the end of it.
FIVE TOOLS
1. House Flip & BRRR Profit Calculator — both exits, side by side. Profit,
return on cash, bridging interest, and how much money you'd leave in on a
refinance.
2. Development Appraisal (GDV-based) — multi-unit schemes. Total development
cost, development finance, profit on GDV, profit on cost, profit per unit.
3. CGT on Property Calculator — gross gain, Private Residence Relief, the 18%
and 24% slices, and what you're actually left with.
4. Holiday Let Income & Expense Tracker — month by month. Occupancy, ADR,
RevPAN and annual profit. Built after the FHL regime was abolished, so it
assumes no reliefs that no longer exist.
5. Service Charge & Ground Rent Tracker — every leasehold demand logged, with
outstanding, overdue and a monthly set-aside figure.
PLUS the How-to-Use Guide (PDF).
5 x Excel files (.xlsx) + guide (PDF). Works in Microsoft Excel and Google
Sheets. Instant download.
Educational tools only. Not financial, mortgage, tax or legal advice.
