Real Estate Investment Tracker: Track ROI Across All Your Properties

Managing multiple investment properties means juggling dozens of spreadsheets—income from five rental properties, acquisition costs from three fix-and-flip projects, monthly expenses, mortgage payments, and tax deductions. Professional real estate investors need one centralized system to track cash flow, ROI, and performance across their entire portfolio.

SheetLink solves this by automatically syncing all your property-related expenses and income to Google Sheets, turning your spreadsheet into a real-time real estate investment dashboard that calculates ROI, cap rates, and cash-on-cash returns for every property.

Why Real Estate Investors Need a Dedicated Tracker

Unlike traditional businesses with a single revenue stream, real estate investors manage:

• Multiple properties - Each with different purchase prices, loan terms, and cash flows
• Complex expense categories - Mortgage interest, property taxes, repairs, depreciation, capital improvements
• Tax optimization - Tracking deductible expenses, 1031 exchanges, depreciation schedules
• Performance analysis - Calculating ROI, cap rates, cash-on-cash returns, comparing properties
• Strategy tracking - BRRRR properties, fix-and-flip timelines, rental vs. flip decision-making

Real estate accounting software like AppFolio or Landlord Studio charges $50-300/month and locks you into their interface. Google Sheets + SheetLink gives you complete control—plus automatic transaction syncing—for a fraction of the cost.

Tracking Multiple Rental Properties in Google Sheets

The key to managing multiple properties is separation with aggregation—each property gets its own detailed tracking sheet, plus summary sheets that compare performance across all properties.

ROI Calculations for Real Estate: Cash-on-Cash, Cap Rate, and IRR

Real estate investors use three main metrics to evaluate property performance:

Annual Cash Flow = Rental Income - Operating Expenses - Debt Service Cash-on-Cash Return = (Annual Cash Flow / Initial Cash Investment) × 100

Net Operating Income (NOI) = Gross Rental Income - Operating Expenses Cap Rate = (NOI / Property Value) × 100

=IRR(array of annual cash flows including final sale proceeds)

SheetLink tip: Build these calculations into your Google Sheet once, then update them automatically with synced expense data. You'll always know your portfolio's true performance.

Fix-and-Flip Expense Tracking

Fix-and-flip projects are all about margin—you need to track every acquisition cost, every renovation expense, and every holding cost to know your true profit.

Create a dedicated "Flip Projects" spreadsheet with tabs for each active project. Use a master tab to track:

Project | Purchase Price | Renovation Budget | Actual Renovation | Carrying Costs | Exit Price | Total Profit | ROI | Timeline (Days)

SheetLink integration: Sync all flip-related expenses from your business account (contractor payments, materials, holding costs). Tag each transaction with the project name, so you can SUMIF all expenses by project. This gives you real-time profit tracking as the project progresses.

BRRRR Strategy Tracking (Buy, Rehab, Rent, Refinance, Repeat)

BRRRR investors need to track each phase of the strategy to ensure projects are profitable:

Track BRRRR deals in a dedicated sheet with columns for each property showing:

Property | Status | Buy Price | Rehab Budget | Rehab Actual | Refi Value | New Loan | Cash Out | Monthly Rent | Monthly Expenses | Cash Flow | Cash-on-Cash (post-refi)

The goal of BRRRR is to recover your initial cash investment through refinancing, then repeat with new properties while those refi'd properties generate positive cash flow. Your spreadsheet should show cash recovered vs. cash deployed for the repeat cycle.

Monthly & Annual Expense Tracking

Rental property expenses come in three varieties—monthly recurring, annual, and variable. Organize them accordingly:

Use a matrix to track all expenses by month and property:

Expense | Property A Jan | Property A Feb | Property B Jan | Property B Feb | ... Mortgage Interest | $1,500 | $1,495 | $2,000 | $1,998 Property Tax | $300 | $300 | $400 | $400 Insurance | $120 | $120 | $140 | $140

SheetLink advantage: Expenses from your business accounts sync automatically, categorized and tagged by property. You see real-time cash flow trends without manual data entry.

Rental Income vs. Expenses Analysis

The core metric for rental properties is monthly cash flow = Rental Income - Operating Expenses. This should be your spreadsheet's centerpiece.

Monthly Cash Flow Summary: Rental Income         $3,500 - Mortgage Interest     ($1,200) - Mortgage Principal    ($200) - Property Tax          ($300) - Insurance             ($140) - Maintenance Reserve   ($300) [set aside for repairs] = Net Cash Flow         $1,360

Create separate rows for:

• Gross Rental Income - Actual rent collected
• Vacancy Loss - Expected vacancy rate (e.g., 5%) deducted
• Operating Expenses - Everything except mortgage
• Net Operating Income (NOI) - Gross minus operating expenses, used for cap rate
• Debt Service - Principal + interest
• Cash Flow - NOI minus debt service, what you pocket each month

Depreciation and Capital Improvements

Two critical tax concepts for real estate investors:

Annual Depreciation = (Property Cost - Land Value) / 27.5 years

1031 Exchange Preparation

A 1031 exchange allows you to defer capital gains taxes by reinvesting sale proceeds into a similar property. Your spreadsheet should track:

• Property Cost Basis - Original purchase price plus improvements
• Accumulated Depreciation - Total depreciation deductions taken
• Sale Proceeds - Sale price minus closing costs and commissions
• Capital Gain - Sale proceeds minus cost basis (this gets deferred with 1031)
• Replacement Property - Must be equal or greater in value within 180 days

Create a dedicated "1031 Exchange" tab that tracks:

Relinquished Property | Sale Date | Closing Proceeds | Identification Deadline | Exchange Deadline | Replacement Property | Purchase Price | Deferred Tax Gain

Real Example #1: Investor with 5 Rental Properties

Meet Jennifer, an investor with 5 single-family rentals across different states:

• Property A (Ohio) - $150k value, $800/month cash flow
• Property B (Kentucky) - $180k value, $1,100/month cash flow
• Property C (Tennessee) - $200k value, $600/month cash flow (newer acquisition, not optimized)
• Property D (Georgia) - $165k value, $950/month cash flow
• Property E (North Carolina) - $190k value, $400/month cash flow (high-appreciation area)

Her Spreadsheet:

• Summary sheet ranking properties by cash flow, cap rate, and 1-year appreciation
• Individual sheets for each property with monthly income and expense tracking
• Master expense sheet showing where she's spending money (property taxes highest in Ohio, insurance highest in Georgia)
• Tax deductions sheet pre-filtered for her accountant (separated deductible vs. non-deductible)
• 1031 Exchange tracker showing Property C is underperforming and might be replaced

SheetLink integration: Jennifer's business checking account syncs all 5 properties' expenses automatically. She can see month-to-month trends and spot underperforming properties instantly. She discovered Property C has a management problem (renter issues) causing lower cash flow than expected—she's now evaluating replacement properties through 1031 exchange.

Real Example #2: House Flipper with 3 Active Projects

Meet Marcus, a professional flipper managing 3 simultaneous projects:

• Project A - Acquisition phase (just closed, starting renovations)
• Project B - Mid-renovation (2 months in, 4 months remaining)
• Project C - Ready to list (renovations complete, getting appraised)

His Spreadsheet:

• Master flip tracker with all 3 projects showing purchase price, rehab budget vs. actual, projected exit price, and estimated profit
• Individual project sheets tracking daily/weekly expenses by trade (plumbing, electrical, general labor, materials)
• Budget variance analysis (is Project B over budget? By how much?)
• Hold-time projection (when will cash be available for next deal?)
• Profit-to-date dashboard showing total capital invested vs. forecast return

SheetLink integration: Marcus's business account syncs all contractor payments, material purchases, and holding costs. He's notified instantly if expenses exceed budget (Project B was tracking 5% over budget on labor costs—he caught it early and adjusted). His accountant gets auto-updated tax deduction sheets monthly.
