Your gain would be broadly £85k. The tax due would depend on how much relief is available - that would depend on how far in the fure the property is sold.
JasmineR wrote:My second question: We will initially be paying the mortgage on an interest only basis, but eventually we may switch this to a repayment mortgage, or a series of one-off payments to reduce the capital owned. How will this affect the amount determined in the first question?
The mortgage will have no bearing on how much tax you pay on any gain.
JasmineR wrote:My third question: Does the equity built in the property during the let period get treated differently to that before the let period begins?
No. In equity you presumably own all of the property, albeit that you owe money to the bank which is secured on the property.
