Indie maker, first-time founder. Built RentSDK because a friend was managing 4 rental units with a Notes app (sometimes excel, ha!) and Venmo screenshots. Most property management software is built for companies, not independent small landlords. RentSDK fixes that. Track Zelle/Venmo payments, manage maintenance requests, store documents, and give tenants their own portal. Free for up to 3 units, forever. No bloat. No $100/mo subscriptions. No demo calls.
