My dh and I found the perfect house in the perfect location. We live in the south (not London), but in a very very pricey town. I've been house hunting since January as the landlord is moving back into our current place. This is only the second time that a house like this has come up.
The landlord received five applications to rent the property. We offered 10% over asking and would pay 12 months upfront. We really really wanted the house. I assume that someone else either offered to pay more or would sign a 24 month lease.
Argh! Back to the drawing board it seems.
