Thanks for the confirmation Sarah.
Some follow on queries/observations.
If I up my residential mortgage prior to actually final 'topping up' to buy new PPR is this newly increased amount assessable for mortgage interest tax relief?
EG.
Now 50K of 100K oustanding
Increase to 60K or 100K outstanding
Later, do a 'top-up' to 70K when purchasing new PPR
Is interest on the 60K now allowable for tax relief? (Assuming the 60K is less than what was originally agreed when mortage was taken out).
Also,
as the rent-a-room scheme allows 7600 odd in tax free earnings it may be better to keep current house as PPR and new one as investment - yes I know you can't decide but seems crazy that one potentially gets more relief under the rent a room scheme than simply moving PPR.
On that note though couldnt one stay in current PPR and remortgage to but an investment property. Then rent out that investment property for say 1 year then do the switch of PPR? What percentage of mortgage would then be allowable?
Apologies if thats a bit confusing - typing fast to catch bus.
Cheers,
Noobie
