Calculators for landlords
For buying, financing, rent, utility costs and management: the calculations landlords and property managers need every day. No account, no sign-up. Every calculation can be shared as a link.
Buying and financing
Purchase costs
Real estate transfer tax, notary, land registry and agent for your state – and the total you need.
Mortgage
Monthly payment, remaining debt after the fixed-rate period and a repayment schedule.
Follow-up financing
What your loan costs after the fixed-rate period – new payment or new term.
Gross rental yield
Annual net cold rent relative to the purchase price – the quick figure for every listing.
Rent and deposit
Rent increase
The calculated ceiling up to the local comparative rent – with capping limit (Kappungsgrenze) and earliest date.
Index-linked rent
New rent based on the consumer price index – with index values and the earliest date.
Rent brake
The highest permitted rent when re-letting in areas with a rent brake (Mietpreisbremse).
Utility billing
CO2 cost split
Which share of CO2 costs you carry as a landlord – based on the tier model.
Heating cost split
Split heating costs by consumption and floor area – under the Heating Costs Ordinance.
Allocation key
Allocate operating costs by floor area, units, persons or co-ownership shares.
Statement deadline
When the utility statement must reach the tenant – and how long they can object.
Management and tax
Default interest
Interest on unpaid rent and claims – to the day, with the current base rate.
WEG deadlines
Notice period for owners’ meetings (WEG) and the deadline to challenge resolutions.
