Mecklenburg‑Vorpommern LFI: 'Wohnungsbau Sozial' portal — which loans remain interest‑free, how to register, and documents to prepare before notarisation

What changed on 5 August 2026 — the portal and the programme

The Landesförderinstitut Mecklenburg‑Vorpommern (LFI M‑V) put its new Förderportal into operation on 5 August 2026; from that date selected programmes — including "Wohnungsbau Sozial Darlehen" — can be submitted digitally through the portal. The LFI has published an announcement and the portal entry point. ([lfi-mv.de](https://www.lfi-mv.de/meldungen/wohnungsbau-sozial-darlehen-jetzt-im-foerderportal-verfuegbar/?utm_source=openai))

The underlying Wohnungsbau‑Sozial programme itself remains the state instrument for subsidising the creation of belegungsgebundene (allocation‑bound) social rental housing by means of long‑term construction loans and, historically, repayment allowances. The LFI describes the Baudarlehen under the Richtlinie as being granted interest‑free for the life of the loan ("zinsfrei bis zur vollständigen Darlehenstilgung"). ([lfi-mv.de](https://www.lfi-mv.de/foerderfinder/wohnungsbau-sozial/?utm_source=openai))

Which LFI loans remain interest‑free (short answer)

The programme page and the LFI guidance state that the Wohnungsbau Sozial Baudarlehen are granted interest‑free for the duration of the loan. This applies to the Neubauförderung (new‑build path) and the modernisation path that are part of the Wohnungsbau Sozial scheme. ([lfi-mv.de](https://www.lfi-mv.de/foerderfinder/wohnungsbau-sozial/?utm_source=openai))

Maximum eligible amounts per square metre are set administratively and published in the state Amtsblatt. For the 2026 notices the Amtsblatt lists maximum Baudarlehen of €3.800/m² on the first Förderweg and €3.540/m² on the second Förderweg; press statements published by the ministry around the same time mention a figure of up to €3.990/m² for the renewed rules. These figures come from different official publications — check the current Amtsblatt or LFI programme page for the authoritative rate that applies to your application.

How to register and authenticate on the LFI portal

You must use the Förderportal for new applications. Registration uses Germany's federal identity services. For private persons the portal accepts BundID; you may authenticate with the online‑Ausweisfunktion or with an ELSTER certificate. Organisations (companies, associations, municipalities) register through "Mein Unternehmenskonto" and typically use ELSTER for authenticated messages. The LFI FAQ describes these routes and links to the BundID / Mein‑Unternehmenskonto guidance. ([lfi-mv.de](https://www.lfi-mv.de/faq-foerderportal/))

Practical tips: create or verify your BundID/ELSTER account well before you start the form; the portal only accepts PDF uploads (max 20 MB per file) and allows one PDF per required attachment — if you have multiple small documents combine them into a single PDF before upload. After submission you cannot edit the form; status and messages appear in the portal and you also receive e‑mail notifications. For technical support the LFI provides a hotline (0385 6363‑8338) and an e‑mail servicedesk address. ([lfi-mv.de](https://www.lfi-mv.de/faq-foerderportal/))

Documentation to have ready before notarisation

The LFI requires that planning and financing for a Mietwohnungsbau project be presented to the authority before application; the formal, form‑bound application must be submitted prior to the start of works unless a special early‑start permission has been granted. That obligation means you should assemble your project and financing papers well before you sign a purchase or construction contract. ([mv-serviceportal.de](https://www.mv-serviceportal.de/leistung?leistungId=112781248&utm_source=openai))

Common documents the LFI will ask for (and which are sensible to have before you meet the notary) include: (a) the completed LFI application form; (b) project description and site plans; (c) current building permit or permit application evidence; (d) detailed cost estimate / financing plan and bank financing commitment; (e) proof of applicant identity or corporate registration and ELSTER tax number for organisations (the portal explains the 13‑digit ELSTER format); and (f) documents that demonstrate compliance with the occupancy/mietpreis rules (the programme sets maximum permitted rents for supported units). Prepare these as single PDFs per required item and confirm the exact checklist in the relevant LFI application form. ([lfi-mv.de](https://www.lfi-mv.de/export/sites/lfi/.galleries/wohnungsbau-sozial/antrag-wohnungsbau-sozial.pdf?utm_source=openai))

If your purchase or build contract is to be notarised, tell your notary you intend to apply for LFI Wohnungsbau Sozial funding and bring the LFI confirmation of receipt or any preliminary case number to the appointment. Notaries cannot substitute for LFI assessments; lenders will expect bank commitment letters; if the timing of a notarial signing depends on the subsidy confirmation, discuss an appropriate condition precedent or postponement clause with the notary and your legal advisor. (This paragraph is explanatory — for legal structuring consult a German notary or lawyer.)

Timing, practical steps and where to check

Processing times depend on completeness. The MV Service Portal and LFI indicate processing can take several months — typically the authority estimates about 3–6 months but this depends on the application quality and programme year budgets. Use the portal to follow your case; once submitted the status and documents are visible there. ([mv-serviceportal.de](https://www.mv-serviceportal.de/leistung?leistungId=112781248&utm_source=openai))

Before you sign anything: (1) verify the applicable per‑m² caps in the current Amtsblatt and the LFI programme page; (2) create/verify your BundID or ELSTER account and gather PDFs; (3) obtain a firm bank financing commitment if you need a bridging mortgage; (4) ask the LFI caseworker about conditional notarisation language if subsidy confirmation may arrive after your intended signing date.
