Net rental income doubles before/after property manager

Average net rental income from a property over about 1.5 years was $5000. Three months ago, we sacked the estate agent who was managing the rental, and our net rental income doubled.

Context:

1. Husband's parents had a property whose parents let out via an estate agent, with a full service arrangement (find a tenant, KYC, manage repairs, fire, safety, legal & compliance, etc.)
2. His parents were elderly and were unable to find repairmen, effect online bank transfers, check if work was done to a satisfactory standard, etc.
3. Net rental income was low. Estate agents were slow to effect repairs and negligent in some respects (long story – we are considering suing them)
4. We sacked the estate agents, and for the past three months have been self-managing the property.
5. Tenant satisfaction is much better, repairs are done within at most, a few days of the tenant raising an issue.
6. Our net rental income has roughly doubled.

Results:
On paper the agent's fees are 13% to find a tenant and 7% for managing the rent. But they seem to always find the most expensive repairmen, and in the end the net rent my parents were getting was consistently about 50% of the gross rent.

Moral of the story:
Self manage your properties if you can.
