Rent increase left unproven
An increase applied on the wrong date, with no trace of how it was reached: in a dispute, nothing backs it up.
JAREMS – rent history kept per lease, dated and auditable.

The real riskThe risk isn’t bad faith —
The risk isn’t bad faith —
it’s forgetting.
And it costs dearly.
Lease renewed by default
Notice served a few days late, and the lease is automatically extended for another full term (Law 820 of 2003).
JAREMS – alerts weeks before every key date, editable letters generated in time.
Insurance lapse
Tenant’s certificate expired, a mandatory service forgotten: in case of damage, the insurer can refuse to cover.
JAREMS – certificates and mandatory maintenance tracked, alerts weeks before each deadline.
Warranty lost
Water heater, AC, pump: one missed annual service and the manufacturer’s warranty is void – the breakdown is on you.
JAREMS – reminders weeks before each service, proofs filed per property.
Documents nowhere to be found
The lease, the inventory and the signed addenda are scattered across e-mails and folders: when a dispute starts, nothing turns up in time.
JAREMS – every document filed per property and per lease, archived as PDF.
Contested receipt
Missing VAT or legal mention: the document no longer holds up in a dispute.
JAREMS – receipts and invoices per lease, archived as PDF.
