Storage Units and Commercial Premises – Getting More from Your Property Portfolio

A 12 m² storage unit brings in €150 a month with zero management effort. A 60 m² commercial unit in a decent location — €2,500 on a three-year lease. Many landlords own these assets alongside an apartment or building and either don't let them at all, or do so with no system in place.

That's wasted potential. And wasted time when billing comes around.

Storage Units – Underrated Passive Income

A storage unit doesn't need an elaborate contract. A simple tenancy agreement covering rent, deposit and notice period is enough. The tenant is usually a neighbour from the same building — a straightforward relationship with little conflict.

The problems come at settlement time: who paid for which month, when does the lease expire, was the deposit returned. In SmartRentier, each storage unit is its own property in the system — with a payment history, documents and a lease-expiry reminder. It works exactly like a flat.

Commercial Units – Different Rules, the Same Tools

Renting commercial premises differs from residential in several important ways: leases are usually long-term, tenants are often VAT-registered businesses, deposits tend to be higher, and utility billing is more complex — separate meters, different tariffs.

SmartRentier handles all of this without modification: you can assign any utility rate, issue a settlement for a specific period, generate a confirmation document. Whether the tenant is an individual or a company — the transaction history is consistent and accessible in one place.

One View of the Entire Portfolio

The owner of a mixed-use building can manage everything in SmartRentier at once: four flats, a ground-floor shop, a garage and two storage units. Each property with its own profile, each tenant with a complete history.

The main dashboard shows at a glance: which units are let, which are vacant, where payments are overdue, which leases expire within the next 60 days. No separate folders or spreadsheets — everything is visible on the first screen.

ROI for Each Property Individually

A commercial unit may bring in higher rent than a flat, but can also generate higher costs: property tax, business insurance, more expensive repairs. Only by setting all income against all costs for a specific property do you get a true picture of profitability.

SmartRentier's financial analysis module does this automatically. You can compare the ROI of the ground-floor shop against the fourth-floor flat — and make an informed decision about which property to develop and which to potentially sell.

Maximising Income Starts with Knowledge

A landlord who has a full picture of their portfolio — all property types, all income and costs, all tenants — can make investment decisions rather than just reacting to day-to-day problems. Raise the rent on a unit that's below market rate. Sell the property with the lowest ROI. Invest in the one that pays back fastest.

SmartRentier gives landlords that knowledge — whatever types of property they hold.
