Baden‑Württemberg L‑Bank housing loans on 18 Sep 2026: rates for ‘Wohnen mit Kind’, Kombi‑Darlehen, Mietwohnungsfinanzierung—and pairing with KfW 297/298 or 300

What changed on 18 September 2026

L‑Bank published new rate sheets for housing programs on 18 September 2026. The sheet for “Wohnungsbauförderung im Hausbankenverfahren” is dated 17 September 2026 and took effect from 18 September 2026. It shows a small upward adjustment in several rows (“Änderung Sollzins” +0.06 percentage points). L‑Bank fixes the interest rate on the day of its loan approval; if the rate was lower on the day the application arrived at L‑Bank, the lower rate applies. Effective APRs can differ if your commercial bank adds fees under the German Price Indication Ordinance (PAngV).

Wohnen mit Kind sits alongside the state’s Eigentumsförderung BW. L‑Bank’s product page notes that for families in Baden‑Württemberg it further reduces the already subsidised KfW rate. ([l-bank.de](https://www.l-bank.de/produkte/wirtschaftsfoerderung/wohnen-mit-kind.html?etcc_cu=onsite&etcc_med_onsite=Interne+Suche&etcc_st_onsite=wohnen&utm_source=openai))

Kombi‑Darlehen Wohnen explicitly requires at least one base subsidy and may sit next to KfW programs such as Klimafreundlicher Neubau (297/298) or Wohneigentum für Familien (300). The program page also links back to the same rate sheet. ([l-bank.de](https://www.l-bank.de/produkte/wirtschaftsfoerderung/kombi-darlehen-wohnen.html?etcc_cmp_onsite=Ergebnislink&etcc_cu=onsite&etcc_med_onsite=Interne+Suche&etcc_st_onsite=wohnen+mit&utm_source=openai))

Mietwohnungsfinanzierung: two distinct paths—and where the rate comes from

L‑Bank runs two different rental‑housing offers, and the way their interest is set differs:

• Mietwohnungsfinanzierung BW – Neubau (socially bound). This is part of the state program “Wohnungsbau BW 2022”. You select a binding period of 10, 15, 25, 30 or 40 years; the interest is fixed for the first 10 years; 25‑ or 35‑year total terms are common; the loan has 2 repayment‑free years and no commitment interest. L‑Bank sets current terms project‑specifically; rates are given on request. Applications go through the local Wohnraumförderstelle and must meet “Neubaustandard Plus”, with an energy‑efficiency expert and, for QNG projects, a QNG assessor. Cumulation with other public programs for the same measure is excluded. ([l-bank.de](https://www.l-bank.de/produkte/wohnungsunternehmen/mietwohnungsfinanzierung-bw-neubau-mw10-mw15-mw25-mw30-darlehen.html))

• Mietwohnungsfinanzierung L‑Bank – Neubau (no social binding). Here L‑Bank passes on KfW’s Klimafreundlicher Neubau funds (programs 298 and 296) to developers and municipalities. Loan amounts per unit are up to €150,000, with 25‑ or 35‑year terms (2 repayment‑free years) and 10‑year fixed. Crucially, for this KfW‑linked route the decisive date is the day KfW receives your application; starting works before KfW has the application is harmful. For the same dwelling you cannot take both KfW 296 and KfW 298, and cumulation for the same eligible costs with BEG or other public programs is barred. ([l-bank.de](https://www.l-bank.de/produkte/wohnungsunternehmen/mietwohnungsfinanzierung-l-bank-neubau.html?etcc_cmp_onsite=Ergebnislink&etcc_cu=onsite&etcc_med_onsite=Interne+Suche&etcc_st_onsite=Mietwohn))

Because these rentals offers tie to either state rules (BW) or KfW rules (KFN), L‑Bank does not publish a single public rate table for Mietwohnungsfinanzierung. Expect pricing tied to project, binding choice and the KfW day rate when you use the KfW‑linked route. Confirm with the Wohnraumförderstelle (BW path) or your Hausbank/L‑Bank contact (KfW‑linked path) before you sign construction or purchase contracts. ([l-bank.de](https://www.l-bank.de/produkte/wohnungsunternehmen/mietwohnungsfinanzierung-bw-neubau-mw10-mw15-mw25-mw30-darlehen.html))

How to pair L‑Bank with KfW 297/298 or 300

Owner‑occupied new build or first purchase: use KfW’s Klimafreundlicher Neubau (297/298) or Wohneigentum für Familien (300, if you have at least one child and meet KfW’s income and occupancy rules) as the base, then add L‑Bank’s Kombi‑Darlehen for the remaining financing need. L‑Bank’s Kombi‑Darlehen page lists KfW 297/298 and 300 as eligible base programs. Family borrowers can also consider “Wohnen mit Kind”, which L‑Bank positions as an additional interest reduction alongside KfW for Baden‑Württemberg families. ([l-bank.de](https://www.l-bank.de/produkte/wirtschaftsfoerderung/kombi-darlehen-wohnen.html?etcc_cmp_onsite=Ergebnislink&etcc_cu=onsite&etcc_med_onsite=Interne+Suche&etcc_st_onsite=wohnen+mit&utm_source=openai))

Numbers: KfW rates change daily and are published to partner banks; two recent signposts help calibrate expectations. On 2 March 2026, KfW announced that for “Klimafreundlicher Neubau” a 10‑year term with 10‑year fixed could be as low as 0.6% effective APR. On 3 August 2026, KfW and the Federal Government improved “Wohneigentum für Familien – Bestandserwerb / Jung kauft Alt”; on that date KfW quoted 0.53% effective APR for a 35‑year term with 10‑year fixed. Treat these as dated examples; check the day’s rate with your Hausbank when you file.

Rental projects: if you take the “Mietwohnungsfinanzierung L‑Bank – Neubau” route, your base funding is already KfW 298/296 passed through by L‑Bank; you can add L‑Bank’s own complementary tranche if there is remaining need, but the product bars stacking with BEG or other public programs for the same costs. If you take the social “Mietwohnungsfinanzierung BW – Neubau” route, coordinate with the Wohnraumförderstelle early; pairing with separate KfW loans for different measures may be possible at project level, but the state program excludes cumulation for the same measure. Document boundaries in your cost breakdown to avoid a repayment claim. ([l-bank.de](https://www.l-bank.de/produkte/wohnungsunternehmen/mietwohnungsfinanzierung-l-bank-neubau.html?etcc_cmp_onsite=Ergebnislink&etcc_cu=onsite&etcc_med_onsite=Interne+Suche&etcc_st_onsite=Mietwohn))

Process points and risks: • Rate lock: for L‑Bank house‑bank programs, the approval‑day rate applies, with a “lower‑of” protection if the application‑day rate was lower. For KfW‑linked rentals, the decisive date is KfW’s application receipt. Starting works too early voids eligibility. ([l-bank.de](https://www.l-bank.de/download/version/1a0ec707-4c52-4a4c-862f-6d2edc100f9d/2026-09-17-konditionen-wohnen-internet_17-09-2026.pdf)) • APRs: your bank’s fees under PAngV can slightly lift the effective rate above L‑Bank’s table. ([l-bank.de](https://www.l-bank.de/download/version/1a0ec707-4c52-4a4c-862f-6d2edc100f9d/2026-09-17-konditionen-wohnen-internet_17-09-2026.pdf)) • Cumulation: read the exclusions carefully—KfW 296 and 298 cannot be used for the same unit; BEG and other public programs cannot fund the same eligible costs. ([l-bank.de](https://www.l-bank.de/produkte/wohnungsunternehmen/mietwohnungsfinanzierung-l-bank-neubau.html?etcc_cmp_onsite=Ergebnislink&etcc_cu=onsite&etcc_med_onsite=Interne+Suche&etcc_st_onsite=Mietwohn)) • Professional help: engage a German energy‑efficiency expert early; they are mandatory under KfW rules and often under BW social funding.
