Understand rental deposit
Why net base rent matters, how liquidity affects move-in and how § 551 BGB frames German deposits.
Use the right base
For German residential rent, the deposit is practically read from net base rent, not warm rent. This keeps service charges from inflating the security amount.
Liquidity still matters
Even if installments can be possible, the deposit competes with first rent, transport and furniture.
No contract review
The calculator shows the magnitude. Specific clauses need separate review when in doubt.
How to use this guide in practice
The guide does not replace a personal decision. It separates recurring cost, one-off cost, documents and uncertainty so a home is not only attractive but workable in daily life.
For German residential rent, the deposit is practically read from net base rent, not warm rent. This keeps service charges from inflating the security amount. Mark what comes from a source and what is only estimated. Housing offers, moving and service charges become error-prone when both are mixed mentally.
Before committing
- Note warm rent, additional costs and one-off start costs separately.
- Collect open points from viewing, contract or handover in writing.
- Carry only reliable numbers into the comparison.

Orientation model. Not tenancy-law advice, contract review or structural assessment. Contracts, defects, area disputes and legal deadlines need a qualified review.
