Track rent, expenses, tenants, and ROI per property - without the complexity of tools built for 500-unit portfolios.
A landlord managing 3 rental properties posted on r/Landlord: "I am drowning in spreadsheets. I have separate files for rent tracking, expense logs, tenant info, maintenance requests, and I am constantly worried I am missing something come tax time."
Real people asking for this
What software/tools do you actually use to manage your rental properties?
I am managing 3 rental properties and honestly drowning in spreadsheets. Separate files for rent tracking, expense logs, tenant info, maintenance requests. Constantly worried I am missing something come tax time. Currently using Google Sheets and my email inbox.
64 comments. Every small landlord with 1-10 units lives this reality. They track everything in Google Sheets, their email inbox, and a folder of lease PDFs. Rent reminders are manual texts. Expense tracking is a mess of receipts in a shoebox. Tax time is a scramble to reconstruct the year.
The existing property management tools - Buildium, AppFolio, RentManager - start at $50-100/mo and are designed for property managers with 50-500+ units. They have maintenance portals, tenant screening integrations, accounting modules, and owner reporting. A guy with 3 duplexes doesn't need any of that. He needs: who owes rent, is it late, what did I spend on repairs, and what's my net income per property.
Build a mobile-first app with four core views: (1) Rent tracker - each unit shows paid/unpaid/late with automatic text reminders, (2) Expense log - snap a receipt, tag it to a property, categorize it, (3) Tenant profiles - lease dates, contact info, payment history, uploaded documents, (4) Dashboard - net income per property, YTD expenses by category, Schedule E-ready tax export.
The tax export is the killer feature. Every small landlord's accountant asks for the same thing: income and expenses by property, categorized for Schedule E. One-click export in January saves hours of shoebox archaeology.
Price at $9/mo for 1-3 units, $19/mo for 4-10 units, $39/mo for 11-25 units. Low price point matches the audience - these are side-hustle landlords, not real estate moguls.
At 20,000 subscribers averaging $15/mo, that's $3.6M ARR. Expansion: add tenant screening ($25 per check, pass cost to applicant), online rent payment processing (2.9% fee), and maintenance request portal.
