How to rent out a flat — a landlord's guide

Renting out a flat can be steady income if you set it up right: a realistic rent, a vetted tenant, a clear lease, and declared income. This guide walks every step — from preparing the flat to handing over the keys.

Prepare the flat and the paperwork

A tidy-looking flat rents faster and holds a higher price. Before you post a listing, check:

  • Small repairs and cleanliness — taps, locks, paint, a clean bathroom and kitchen. First impressions lift the price.
  • Proof of ownership — a cadastre extract (property sheet) in your name. If the flat is unregistered or encumbered, sort that out first.
  • Settled utilities and debts — electricity, communal charges, property tax. Debt "travels" with the flat and causes trouble.
  • Good photos — bright, level, every room. A listing with poor photos goes unseen.
  • Inventory — list the furniture and appliances that stay (for the lease and the handover record).

Not sure the property is "clean" in the cadastre? See Checking a property in the cadastre.

How to set the rent

Too high = an empty flat; too low = money left on the table. Three checks:

  • Compare similar listings — same district, size, floor, furnishing. That is your market frame.
  • Rental yield — gross annual rent is typically around 3.5–5.5% of the flat's value. From the value you get a rough monthly rent.
  • Season — in university cities demand rises in summer, ahead of the academic year (see below).

On Kaza.rs valuation you enter the address and size and get a rough rent and value estimate for that exact flat — a good starting point before you price it.

Find and screen the tenant

A good tenant is half the job. You can do it yourself (a listing) or via an agency:

  • Yourself — more work showing and vetting, but no commission.
  • Via an agency — the agency finds and screens the tenant and prepares the lease; check it is licensed.

Before signing it is sensible to check employment/steady income and, for students, a guarantor (a parent). The deposit is your protection against damage and non-payment — more on that below.

Student rentals — the season and specifics

In Belgrade, Novi Sad, Niš and Kragujevac demand peaks from July to September, ahead of the academic year. If you target students:

  • Furnish the flat — students want it move-in ready; furniture and appliances mean a higher price and a faster let.
  • Lease term — often tied to the academic year (10–12 months); state the period clearly and whether it renews.
  • Guarantor — since a student rarely has steady income, a parent as guarantor in the lease cuts the risk.
  • List early — the content and the listing should be ready before the peak (June–July), not once the season has passed.

Lease, deposit and handover

Always write a lease, even when renting to someone you know — it protects both sides. The essentials:

  • Deposit — usually one month's rent; returned at the end if there is no damage.
  • Handover record — the state of the flat, the meter readings (electricity, water) and the inventory on move-in day.
  • Who pays the utilities — state it clearly (as a rule the tenant pays the running costs).
  • Filing and tax — rental income is declared and taxed.

We split the detail on the lease, deposit and rental tax into a separate guide: The lease — deposit, filing and rental tax.

What to watch out for

  • No lease, no protection. A verbal deal leaves you without evidence in a dispute or over damage.
  • Undeclared rent is a risk. Rental income must be declared; not declaring it carries a tax risk and leaves you without legal protection.
  • Deposit with no record. Put the amount and return terms in the lease and make a handover record — otherwise it is easily disputed at the end.
  • Skipped tenant screening. A few minutes of checks (income, guarantor) saves months of trouble.

Frequently asked questions

How do I set the rent for my flat?

Compare similar listings in the same district and estimate the yield (gross annual rent is typically around 3.5–5.5% of the flat's value). On Kaza.rs valuation you get a rough rent and value estimate for the specific address and size.

How big a deposit should I ask for?

Usually one month's rent. The deposit covers damage and non-payment and is returned at the end of the lease if there is no damage. Always put the amount and return terms in the lease.

Do I have to declare renting out my flat?

Yes. Rental income is declared and taxed. Who files depends on whether the tenant is a natural person or a legal entity — see the guide "The lease — deposit, filing and rental tax".

Do I need an agency to rent out my flat?

You do not have to, but an agency can find and screen the tenant and prepare the lease. If you go through one, check it is licensed (entered in the brokers' register).

When is the best time to rent to students?

Demand in university cities peaks from July to September, ahead of the academic year. The listing and the flat should be ready before that peak, already in June.
