Thank you for your replies and info.
What annoyed me about this situation is that they requested work done on the property and 3 weeks after I completed this for them they gave me their notice. I did this work at a substantial cost and although it probably will add value to the property when I enventually sell, it wasnt a very suitable time for me at the time to do it as regards my cash flow. I also treated them cosiderable well at christmas (ie. some cash refund on rent.)
I consider myself a fair man in all circumstances and I dont want to be paid rent on the double by holding their deposit, if I can get someone in immediatly, but I could be at a loss of 2-3 weeks rent after they move out, before I can identify a suitable tenant to rent the property again.they did sign the lease for a year !!
ps: The property is advertised and I did have a viewer today and the property was a mess and absolutly no effort was made to make it in a presentable manner for the viewers by them. how fair is this , They dont give a s... if I re rent or not once they go.
