Should I remortgage residential to pay off higher buy to let mortgage?

[gottogetthroughthis]

Should I remortgage my very small residential mortgage and use that to pay off my buy to let mortgage which is much higher?

No, even with new rules coming in next year, you will still get some tax relief on your BTL mortgage (full tax relief if the rent doesn't take you over the higher tax threshold) so it is always worth keeping the mortgage higher on a rental property than your own home.
