Mortgages

What to record for every mortgage payment

Date, cash out, interest, principal and remaining balance — the five fields that keep a loan honest.

Maintenance

From tenant report to resolved repair

Keep the original report, the vendor, and the close note on the same unit — so a repair does not become a chat thread.

Documents

A simple version history for property files

Stop renaming PDFs. Keep the current lease, insurance and house file on the property, with access that stays scoped.

The five numbers worth checking every week

Tenant operations

Lease-linked access without oversharing

Tenants should see their home, their lease and the files you chose — not the rest of the portfolio.
