**Based on what you’ve shared, I’d lean towards starting a pension before buying another rental property**, particularly if an employer would contribute. You already have exposure to property; a pension could help spread your retirement savings across other investments.

Assuming you’re in the UK:

- **A downturn can reduce a pension’s value, sometimes substantially. Losing everything in a broadly diversified pension would be extremely unlikely.** A pension is an account holding investments: the risk depends on what it holds. Funds can spread money across many companies and include bonds or cash. Your investment mix should reflect how soon you’ll need the money and how much loss you can tolerate.

- **Pensions have tax advantages.** For example, an eligible £80 contribution to a personal pension using basic-rate relief at source becomes £100 invested. Employer contributions can add further value. Most pension withdrawals are taxable, and access is normally restricted until age 55, rising to 57 from April 2028.

- **Property carries downturn risk too.** Prices can fall, tenants can leave, and repairs or higher mortgage costs can turn a break-even rental into a loss. Borrowing magnifies losses on your own equity. [MoneyHelper’s buy-to-let guide](https://www.moneyhelper.org.uk/en/blog/buy-or-rent-a-home/buy-to-let-mortgages-explained).

Your property’s “break-even” position needs a closer look. Does that include tax, maintenance and an allowance for vacant periods? If your mortgage payments include repayment of principal, you may also be building equity despite having no spare monthly cash.

My suggested next step is to keep a cash reserve for emergencies and rental costs, then check any workplace pension and the contributions available from your employer. Compare another property only after calculating its return after all costs. Pension protection can apply to certain provider failures, but **it does not reimburse ordinary market losses**.

Which country are you in, how old are you, and are you employed or self-employed? Those details would make the comparison much more useful.
