If your pension pot(s) are anything like half decent, they should be increasing a an annual rate of 5% per annum. A couple of mine are running at over 6. So I see no point in pulling huge lump sums out before you need the money, especially as it throws one into higher rate tax - something I for one have sought to avoid in my working life by investing in pensions. Point taken, though about the tax free sum, which I like the idea too of investing in UK property. It gives an annual income plus the reasonable expectation of capital growth in the longer term.
Not sure what point Talbot is making - property rental income is income for tax purposes, less any explainable expenses like mortgage interest. But it makes no sense to have a buy to let mortgage if one has the capital to fund outright.
