Compare Two Retirement Planning Strategies

You are in your forties and wondering whether to pile everything into pensions or spread it across pension, ISA, and property. This compares the two approaches across five dimensions, tax efficiency first, so you can see the trade-offs for a UK worker like you. It is education to inform your thinking, not regulated advice about what to actually do.

**Compare the two strategies across five dimensions:**
1. Tax efficiency: pension tax relief vs ISA tax-free growth vs property capital gains treatment
2. Liquidity: accessibility before retirement age under each strategy
3. Risk profile: concentration risk, market risk, and property market risk
4. Complexity and management burden: what each strategy requires the investor to do each year
5. Flexibility at retirement: what options each strategy creates for drawing income

If the person has significant existing property debt, note how this changes the comparison.
