It seems that for an investment prooperty the greatest efficiency lies in paying an intrest only mortgage as you cannot sell the property for 10 years and the higher the interest repayments the more you claim for income tax purposes while preseving and lengthening the tax allowance against rental income under the Section 23 property.
Obviously this means a larger capital repayment when the 10 year period of the Section property is at and end.Is my understanding correct here ?
