Rent out an apartment in 8 clear steps
This is how a rental with MIA Immobilien works – structured, legally sound and with clear responsibilities. You stay in charge throughout.
A residential rental follows eight steps: onboarding, market-rent analysis (§§ 558, 556d BGB), listing, marketing, qualified viewings, GDPR-compliant credit check, contract under § 535 BGB and documented handover. Typical time: 2–6 weeks.
1. Onboarding & property intake
We review floor plan, energy certificate, utility statement and align on your goals – duration, tenant profile, target rent.
2. Market rent analysis
Local comparable rent (§§ 558 ff. BGB), check of the rent cap (§§ 556d ff. BGB, state regulation) and comparables from our 23-year regional practice.
3. Professional listing
High-end photography, floor plan, transport, energy data – fully compliant with GEG and GDPR.
4. Marketing
ImmoScout24 Premium (Gold Partner), Immowelt, our applicant database, and on request discreet off-market from our waiting list.
5. Qualified viewings
Individual and group viewings, pre-screened applicants. You only meet candidates who fit economically and personally.
6. Credit check
Tenant self-disclosure (admissible questions per Federal Court of Justice), SCHUFA with consent, income proof – GDPR-compliant throughout.
7. Contract & deposit
Legally sound residential contract (§ 535 BGB), deposit up to 3 cold rents (§ 551 BGB), utility agreement (§ 556 BGB, BetrKV).
8. Handover & aftercare
Documented key handover with meter readings, digital archive and – on request – continuous support throughout the tenancy.
The MIA flat fee: 1 % of annual rent.
One price, no small print, no success hurdles. You only pay once your property is let and the contract is signed. Everything else is included.
Residential rentals are governed by the orderer-pays principle (§ 2 (1a) WoVermRG): the commission is paid by the party who instructed the agent – usually the landlord. Our 1 % annual-rent fee is well below the statutory cap of two net cold rents. Tenants pay nothing.
The orderer-pays principle – what it means for you
Since 2015, residential rentals fall under the orderer-pays principle (§ 2 (1a) WoVermRG): the commission is paid only by whoever instructed the agent. If the landlord instructs us, the landlord pays – the tenant pays nothing. A tenant may only be charged commission if they themselves instructed the agent (§ 3 (2) WoVermRG), capped by law at two net cold rents plus VAT.
Legal basis: § 2 WoVermRG and § 3 WoVermRG.
Market rent, rent cap & ceiling
The right rent is the foundation of any successful letting – too low means lost yield, too high means vacancy and, in cities with a rent cap, legal exposure. We work only with robust data and current legislation.
The local comparable rent is the reference point under § 558 BGB. The rent cap (§ 556d BGB) limits new-tenancy rent to 10 % above the local comparable – in areas declared tight housing markets. In Baden-Württemberg this includes Heidelberg and Mannheim.
Local comparable rent
Derived from the rent index, rent database or expert opinion. Most cities in the Rhine-Neckar region maintain a qualified rent index under § 558d BGB.
§ 558 BGB →Rent cap (Mietpreisbremse)
Maximum 10 % above the local comparable rent when re-letting in designated areas. Exceptions: new builds from 1 Oct 2014, comprehensively modernised units, previous rent.
§§ 556d – 556g BGB →Rent-increase ceiling
For existing tenancies, rents may be raised to the local comparable by no more than 20 % in three years (15 % in tight markets) – § 558 (3) BGB.
§ 558 Abs. 3 BGB →Solvent tenants – GDPR-compliant screening.
A thorough credit check protects the landlord from arrears – but not every question is legal. We work with a standardised screening that is legally clean, non-discriminatory and GDPR-compliant.
We collect only data that case law allows (§ 1 AGG), obtain consent under Art. 6 (1) (a) GDPR, and delete all data after completion. Questions on marital status, religion or pregnancy are inadmissible.
What we ask – legal & necessary
- Name, address, date of birth
- Employer & type of employment
- Net income (3 months proof)
- Household size (number of people)
- Current and previous housing
- SCHUFA credit report (with consent)
- Previous-landlord reference (optional)
What we never ask – inadmissible
- Marital status & family planning
- Religion
- Party membership & political views
- Ethnic origin, nationality (unless required for residency)
- Pregnancy
- Sexual orientation
- Unrelated criminal records
- Impermissible data like the raw SCHUFA score (credit rating suffices)
GDPR-compliant process
Consent form up front, purpose-limited use, access only for the assigned advisor, automatic deletion after completion – documented in our internal processing register.
Legally robust outcome
You receive a structured tenant recommendation with credit rating, income-to-rent ratio and previous tenancy – as a basis for your decision, never as an automated rejection.
Documents we need from you as landlord
Complete paperwork shortens time to let measurably. On request we obtain missing documents for you – from the energy certificate to the land register extract and the WoFlV area calculation.
Mandatory: energy certificate (§ 80 GEG) and correct WoFlV area statement. Recommended: prior-year utility statement, house rules, floor plan. For the contract: legally sound template, handover protocol with meter readings.
Energy certificate
RequiredMandatory under § 80 GEG, to be shown by the viewing. Valid for 10 years. Fines up to € 10,000 for non-compliance.
Floor plan & area calculation
RequiredPer WoFlV. Basis for correct area disclosure in listing and contract – discrepancies over 10 % give tenants rent-reduction rights (Federal Court case law).
Utility statement (prior year)
RecommendedLets applicants assess the realistic warm rent. Transparency raises conversion.
House rules
RecommendedFor condominium properties: declaration of division + community rules. Become part of the contract.
Tenant self-disclosure form
RequiredWe provide the current, legally vetted template.
Handover protocol
RequiredMeter readings for electricity/gas/water, key count, condition – documented with photographic evidence.

Let privately or with an agent?
Letting privately saves the commission on paper (1 % annual cold rent) – but takes 20–40 hours of your time and usually leads to longer vacancy due to weaker reach. Our take from 23 years in practice: the 1 % flat fee almost always pays for itself in reduced vacancy and preventive credit checks.
Letting privately saves the flat fee but costs time, tends to extend vacancy and raises the risk of void contract clauses and GDPR breaches. With an agent you gain reach, structured credit checks, a legally sound contract and liability protection.
The 7 most common mistakes when letting property
These are the mistakes we see over and over in rental practice – each one can lead to arrears, refund obligations or fines. Here is how to avoid them from day one.
Most common: asking rent above the cap (§ 556d BGB), inadmissible questions (§ 1 AGG), no energy certificate (§ 80 GEG), excessive deposit (§ 551 BGB), vague service-charge clause (§ 556 BGB / BetrKV), missed utility-statement deadline and a superficial credit check. Each one can get expensive fast.
Rent above the statutory cap
In cities with rent-cap regulation (e.g. Heidelberg, Mannheim), new-tenancy rent may exceed the local comparable by no more than 10 % (§ 556d BGB). Excess rent can be reclaimed under § 556g BGB – tenants have formal objection rights.
Inadmissible questions in the self-disclosure
Questions on marital status, pregnancy, religion or political views are inadmissible (§ 1 AGG and Federal Court case law). Using them risks damages claims and reputational harm.
Missing or incorrect energy certificate
§ 80 GEG requires it to be shown by the viewing. Non-compliance attracts fines up to € 10,000. Energy values in the listing are also mandatory.
Deposit above the statutory cap
For residential, a maximum of three net cold rents (§ 551 (1) BGB). Any excess demand is void; the tenant can reclaim it – even years later.
No concrete service-charge clause
§ 556 BGB together with BetrKV require allocable costs to be named concretely. A blanket reference to BetrKV is not enough (Federal Court XII ZR 164/16). Consequence: the tenant owes only the base cold rent.
Missing the utility-statement deadline
The statement must reach the tenant within 12 months of the billing period's end or any follow-up claim lapses – § 556 (3) s. 3 BGB. We remind you in good time.
Superficial credit check
Without income proof and a SCHUFA report, arrears risk spikes – in our practice the single most expensive mistake a landlord makes. A solid up-front check pays back the 1 % fee many times over.
How long does letting actually take?
In our Rhine-Neckar practice, a market-rate apartment typically lets within two to six weeks from listing to signed contract. Excessive rent or incomplete paperwork visibly extend vacancy.
Realistically 2–6 weeks for an apartment in the Rhine-Neckar region. There is no official benchmark – it depends on price, location, condition and size.
Note: the time ranges are our own practice in the Rhine-Neckar region, not industry statistics. Properties needing renovation or with special locations may differ.

Frequently asked questions about letting property
The ten questions landlords in the Rhine-Neckar region ask us most often – with pointers to the relevant statutes.
For residential rentals, the "orderer-pays" principle in § 2 (1a) WoVermRG applies: the agent's commission is paid only by the party that instructed the agent – usually the landlord. The tenant may be charged no more than two net cold rents plus VAT, and only if they instructed the agent themselves (§ 3 (2) WoVermRG). Our MIA flat fee of 1 % of the annual cold rent per unit is paid by the landlord – the tenant pays no commission.
