Sorry, I don't know what that is.
It's one I bought from Smiths that both parties have signed but after numerous requests for him to pay his rent as agreed, I sent him a letter stating that his tenancy would be renewed on a month by month basis on the understanding that he would pay his rent on time, ie the 1st of each month. This was last July and he hasn't kept to the agreement and I can't afford to carry on like this.
The STA was for 6 months but the monthly renewal was for 6 months on the understanding that he paid on time.
I've just checked and it's May 2011 - the original AST shows that he moved into the property in November 2010 and it was a 6 month short hold tenancy agreement.
