Buy-to-let property for civil servants: status, bank and honest calculation

Michael Pauker · 2026-10-13

Your salary arrives on time, every month, until you retire. After the probationary period, the employer practically cannot dismiss you. Banks know this too, and many providers of capital investments therefore specifically target teachers, police officers and administrative officials.

Advertising often makes it sound as if tenants and the tax office pay the instalment. For some, this is roughly true. For many civil servants it is not, because their tax rate is lower than the calculations in the brochure assume. A civil servant teaching couple with income splitting often ends up with a marginal tax rate of around 36%, not 42%.

We show what the status actually achieves at the bank, what the civil servant loan is all about and what a let flat costs for a typical civil servant income before and after tax.

01What civil servant status achieves at the bank

Since 2016, every bank must check before granting a real estate loan whether you can repay it from your income. The value of the flat alone is not sufficient for this (§ 505b Para. 2 BGB). This is precisely where the advantage for civil servants lies. Your income is predictable until retirement, and the pension is also known.

Many banks evaluate this favourably. Some are more likely to also finance the purchase closing costs for life-tenure civil servants; some offer slightly better interest rates. However, there is no fixed civil servant discount. Equity, loan-to-value ratio and the household budget calculations are what primarily change the interest rate.

One item is often forgotten for civil servants. Private health insurance for the part that the allowance (Beihilfe) does not cover is a fixed expense. It belongs in the self-disclosure. If you leave it out, it will be noticed at the bank at the latest, and in the worst case, the notary appointment will fall through.

02Civil servant loans and secondary activities: two terms often confused

What is a civil servant loan?

End-of-term loans are usually offered under this name. You only pay interest over the term. At the same time, you save into a life or pension insurance policy, the payout of which is intended to repay the loan at the end. Because nothing is repaid, the interest remains high over the entire term.

The risk lies in the insurance. If the payout is not enough at the end, a residual debt remains that you must repay from other money or with a new loan. For a let flat, a normal annuity loan with fixed repayment is usually easier to oversee. With a civil servant loan, always have it shown what interest rate the insurance calculates with and what happens if it turns out lower.

Do I need permission to let?

No. For federal civil servants, managing one's own assets is expressly not a secondary activity requiring approval (§ 100 Para. 1 No. 1 BBG). The civil service laws of the states contain comparable rules. Check this for your state if you want to build up many units or offer services related to letting.

03Customer questions with example calculation

Sarah, 38, and Daniel, 40, are both civil servant teachers, she full-time, he with reduced hours. Together they have a taxable income of £105,000 and are jointly assessed. The names are fictitious, the figures are a calculation example and not a forecast.

They are looking at a let existing flat: built in 1998, 65 sqm, purchase price £230,000, cold rent £11 per sqm. They pay the purchase closing costs of £18,400 from savings. They finance the purchase price with 3.7% interest and 2% repayment because they deliberately see the rate as a savings rate.

"How much do I have to pay out of my own pocket each month?"

Interested parties ask this question in almost every conversation, and it is the right first question. Here is the answer for Sarah and Daniel, first before tax.

Before tax, around £508 per month is missing; after tax, it's around £371. At the same time, you pay £383 per month in repayment. Purely economically, you are therefore building up slightly more assets than you are paying in, as long as rent and interest remain the same.

"How much do I save at my tax rate?"

The tax side looks like this. The tax office calculates with interest, depreciation and deductible costs. Repayment and reserves do not count.

Every euro of loss brings Sarah and Daniel back around 36 cents. That is decent, but far from the 47 cents that many brochures calculate with. Anyone who sets a tax rate of 42% for you with a teacher's salary with splitting is sugarcoating the property.

Existing or new build?

For a new build flat with degressive depreciation of 5%, the tax loss would be significantly larger. With the example flat from our guide for doctors, £300,000 purchase price and 60 sqm, the teaching couple would achieve £5,164 in tax savings. Before tax, however, this flat costs £585 per month, and after tax around £155.

The new build looks better after tax but requires £70,000 more in credit and a purchase in the year of completion. The degressive depreciation decreases slightly every year. Which variant fits depends on what you can carry before tax and how long you want to hold.

"Why monthly? Isn't the tax return done annually?"

The question comes from one of our conversations and affects civil servants just as much as employees. Without further action, the tax savings only come with the assessment, i.e., up to one and a half years later. You can, however, have the losses entered as an allowance (§ 39a Para. 1 Sentence 1 No. 5 EStG). Then the payroll office deducts less wage tax each month. For purchased flats, this is possible from the year after acquisition (§ 37 Para. 3 EStG).

What remains of your rent after tax? Enter cold rent, interest, depreciation and your income.

04Pension and tax in old age

The pension is predictable. For federal civil servants, the retirement salary is 1.79375% of the pensionable emoluments for each year of service, up to a maximum of 71.75% (§ 14 Para. 1 BeamtVG). The states have similar rates.

What often gets forgotten: Civil servants must pay full tax on their pension. While employees only pay tax on a portion of their statutory pension (depending on the year of retirement), the pension is considered income from employment (§ 19 Para. 1 No. 2 EStG).

If you then have rental income from a paid-off flat, this is added to the pension. Your tax rate in retirement remains relatively high. A flat is therefore a good supplement, but it is not a "tax-free" pension.
