TRS on mortgages

Being a ftb on the first property and using up just over two years of the higher relief. would the higher relief carry over to my current property(until the 7 years is up)
Yes. You carry the remaining 5 years of "FTB" relief over over.
 

Does this mean that the mortgage needs to be in both names or just that i am married? - the thresholds mentioned are now 20k for married person - i am + FTB however the house is solely in my name ( not sure about the mortgage - i think that is in both names ) should i be entitled to the upper limit? my wife has a separate mortgage on another property as a FTB ( for which she is not claiming TRS )
