Plot to handover. Six tools, one build.
SIX TOOLS
1. Feasibility & Plot Appraisal — does the plot stack up? Land, stamp duty,
build cost per m², fees and contingency against end value, with sensitivity
on the build cost.
2. Budget Tracker & VAT Reclaim Log — eight build stages, budget versus actual,
plus a full DIY Housebuilders VAT reclaim log and eligibility guide.
3. Mortgage Drawdown & Cashflow — stage drawdowns against an 18-month cashflow,
showing the tightest cash point in the whole build.
4. Contractor Quote & Payment Comparison — three quotes across 13 trades, plus
deposits, interims and balances.
5. Build Programme & Gantt Chart — 20 pre-loaded tasks, bars that draw
themselves.
6. Snagging & Defects List — every defect logged by room, trade and priority,
through to closed.
PLUS the How-to-Use Guide (PDF).
Self-builds don't usually fail on the build. They fail on cashflow, on VAT
that never got reclaimed, and on a budget nobody was watching. These are the
tools for those three.

Everything you need to analyse, track and tax-plan a rental portfolio.
FOUR TOOLS
1. Rental Yield & ROI Calculator — appraise a deal before you buy. Gross and
net yield, cash flow, cash-on-cash ROI, break-even rent, and the lender's
stress test that decides whether you get the mortgage at all.
2. BTL Portfolio Tracker — one row per property, up to 20. Equity, LTV, cash
flow and yield each, rolled up on a live dashboard.
3. Section 24 Tax Calculator — what the mortgage-interest restriction actually
costs you, versus full deduction. Every rate editable.
4. HMO Room-by-Room Tracker — rent, deposits, occupancy and shared bills for
a shared house, with occupancy and net income on a dashboard.
PLUS the How-to-Use Guide (PDF) — a plain-English walkthrough of all four.
Buy a deal with the first. Track it with the second. Understand what the
taxman leaves you with the third.

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.
