“Dear Landlord,
We were surprised to receive your text message regarding your intention to change our rental agreement with you.
We very much enjoy living in this property and have made it our home, looking after it accordingly. We are model tenants, always paying our rent in full on time and have been commended by the letting agency for being one of the best tenants they have ever dealt with.
Therefore we are shocked that you would risk losing us as good tenants in order to gamble on charging well over the market value for a flat in this area.
We hope you understand that financially we would be very foolish to pay the 40% increase you suggest as it is hugely over the market value for this property and would mean we were paying an unnecessary £4250 on accommodation over a year. This is obviously far above inflation and with the price of living and energy costs rising, it’s just not good financial sense for us (or indeed any other propective tenant). Even factoring in the costs of moving, we would still be financially better to move into any other similar property in the area as you would have made yours very uncompetitively priced.
We would really hope you would reconsider your intention, as we are very happy in the property have no intention of moving , meaning that you still have guaranteed income from your flat, avoiding any costly empty period when you try to find new tenants at your new uncompetitive rent.
We would be really happy to negotiate a rent increase in line with market value and inflation and would suggest “£?”
If this makes good financial sense to you then we’d be happy to accept and continue looking after the property. You would need to serve us a Section 13 Notice to increase the rent and allow a full rental period of notice before the new rent can take effect.
If after careful consideration you still feel that you want to risk acting as an agent yourself to rent a property 40% over the market value in the current financial climate, then we will sadly need you to start eviction proceedings towards us. We understand that these can be costly and take a long time and would urge you to reconsider.
All the best
Us “
I’d email something like this with appropriate links to information about legal processes etc.
