Where they talk

  • r/Landlord
  • r/smallbusiness
  • r/uklandlords
  • r/OntarioLandlord
  • r/CommercialRealEstate
  • r/realestateinvesting
  • r/shitrentals

Tools they use today

  • Excel
  • Zillow
  • Claude
  • DoorLoop
  • Apartments.com
  • Word
  • AppFolio
  • Beagle

Why those fall short

  • no approval step, support uninformative, tenant claim taken as correct
  • AI makes tenant emails longer and harder to process
  • flagged applications still need manual review; fake docs get cleaner
  • Recoveries resolve at building and tenant level simultaneously; spreadsheets cannot handle the circularity
  • governing docs outdated; no automated process; enforcement depends on board discretion
