Landlord & BTL Toolkit — Complete (4 tools)

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.

4 x Excel files (.xlsx) + guide (PDF). Works in Microsoft Excel and Google

Sheets. Instant download.
