Rent to Rent Cashflow Spreadsheet:
How to Use One and What to Track
A cashflow spreadsheet is the most important financial tool for any rent to rent operator. This guide explains what your spreadsheet must track, how to structure it, and how to use it to make better deal decisions.
What This Guide Covers
Why Every Rent to Rent Operator Needs a Cashflow Spreadsheet
Operating rent to rent without a cashflow spreadsheet is like driving without a dashboard — you have no idea how fast you are going until something goes wrong. A well-built spreadsheet gives you:
- Deal analysis before signing — model the income and costs for any potential deal before you commit. Know your break-even occupancy, your monthly profit at various occupancy levels, and your ROI on setup costs
- Portfolio tracking — see your total income, costs, and profit across all properties in one place. Identify which properties are performing and which are underperforming
- Cash position visibility — track your bank balance, maintenance reserves, and upcoming payments. Never be caught short by a quarterly expense you forgot to budget for
- Tax preparation support — categorised income and expense records make your accountant’s job easier and reduce your accounting fees
What Your Spreadsheet Must Track
For each property, your spreadsheet should track:
- Income: Monthly room rates by room, occupancy status, total monthly income collected, total monthly income expected
- Fixed costs: Landlord rent, utilities (gas, electricity, water, internet), insurance, council tax, HMO licence (monthly equivalent)
- Variable costs: Maintenance and repairs, cleaning costs, tenant sourcing fees (SpareRoom, Rightmove), compliance checks (gas safety, EICR renewals)
- Net monthly profit: Gross income minus all costs
- Vacancy status: Which rooms are occupied, which are void, expected re-letting dates
- Contract details: Landlord rent contract start and end date, break clause dates, rent review dates
Portfolio-Level Tracking
In addition to per-property tracking, your spreadsheet should have a portfolio summary tab that shows:
- Total monthly income across all properties
- Total monthly costs across all properties
- Total monthly net profit
- Portfolio occupancy rate — total rooms occupied divided by total rooms
- Total capital deployed — cumulative setup costs across all deals
- Portfolio ROI — total annual net profit divided by total capital deployed
- Cash reserve balance — your float fund and maintenance reserve
Frequently Asked Questions
Should I use Excel or Google Sheets for my rent to rent spreadsheet?
Either works well. Google Sheets has the advantage of cloud-based access from any device and easy sharing with your accountant or VA. Excel offers more powerful formula and pivot table functionality for complex analysis. For most operators managing up to 10 properties, Google Sheets is the more practical choice. For more detail, see finding the right accountant.
How often should I update my rent to rent cashflow spreadsheet?
Update the income section monthly when rent is collected. Update costs monthly when invoices are received or payments made. Review the portfolio summary monthly as part of your business review. The goal is that your spreadsheet is always an accurate reflection of your business position — not something you only look at at year end.
Does my accountant need access to my spreadsheet?
Your accountant will typically want to see your income and expense records, which your spreadsheet provides. Many property accountants work from spreadsheet exports or accounting software exports rather than the spreadsheet itself. Discuss with your accountant what format they need your records in — and make sure your spreadsheet is structured to produce it easily.
