4. Space is a relative concept
The spacious double room they advertised online will probably turn into a small closet with a queen-sized bed in it, you have ever seen. Be aware that 'spacious' is in the list of the top 5 words in an agent's vocabulary, and it's often misused.
5. "It's at a great price for the area"
Nothing is ever too expensive for the London lettings market. No matter what, "this is the best price you will ever find in this area" - yes, sure.
6. "That will be fixed before your start of tenancy"
Perfection doesn't exist, we may all agree to this one. But every London home will have that "minor thing the landlord will fix before you move in". Chances are, it will never get fixed for a long, long time.
7. They have an answer to everything, even when they don't
When an agent doesn't know the answer to your question, they will make up something - no matter what. Need I say more?
8. referencing = easy cash for the agent
Referencing is not such an expensive process as most agents try to make you believe. Mostly, it is simply another good opportunity to make some easy extra cash at your expense.
9. Cheapest furniture only, please!
Have you agreed for a furnished home and let the agent choose the furniture? Expect your mattress to be quite uncomfortable: agents always know where to find the cheapest and ugliest furniture in town.
