You could stop using capitals for a start.

You are not liable for capital gains tax on your principal residence. If you own 2 houses, you can nominate one to be your principal residence within 2 years of buying the second. If you don't nominate, the principal residence will be decided by your local tax office by looking at the situation.

WE HAD A PROPERTY GIFTEDTO US @ £180.000 AND OBTAINED PLANNING PERMISSION ON THE SIDE GARDEN

TO BUILD ANOTHER PROPERTY.

MANY YEARS LATER THE ORIGINAL PROPERTY WAS SOLD FOR £245.000 AND THE NEW BUILD HOUSE BECAME

OUR HOME FOR JUST OVER 6 MONTHS.

DUE TO SCHOOLING DISTANCES WE HAD TO MOVE YET AGAIN AND LET THE PROPERTY AS THE CRASH

RESTRICTED THE SALE. WE HAVE NOW BEEN TOLD WE MAY BE LIABLE TO CAPITAL GAINS ON THE

PROPERTIES AND THE LAND USED AS THIS HAD ITS OWN VALUE? WE WERE ALSO

ADVISED BY A FRIEND THAT THE HOUSE CAN BE SOLD WITHIN 3 YEARS AND SHOULD NOT HAVE TO PAY ANY

TAX. WE ARE SO CONFUSED AND DON'T KNOW WHAT TO DO?
