They didn't do a proper check-through after previous tenants left, and didn't take care of most of the condition issues from previous tenants.
Forced a 13-month lease after 12-month was already agreed on.
Swapped between who needed to be paid.
Communication was a 1-way street, they sent us their problems and needs but completely ignored our requests to fulfill their obligations.
Unfulfilled obligations include: mold, general cleanliness, kitchen sink pipes leaking, carpet tack sticking through.
The only needs they fulfilled were mulch, and replacing the leaking kitchen faucet (a month before our lease was up, even though we told them initially).
