Programme profile 297/298

Terms and application

€150k max per residential unit
25% repayment subsidy
EH 40 standard required
QNG-Plus certification

Important: application sequence. KfW funding lapses if applied for retroactively. I make sure the application sequence is correct — this is the most common and most expensive mistake when financing buy-to-let property.

KfW 297/298 for investors — what is decisive

Apply before the purchase contract — no exceptions. The KfW application must be filed before signing the purchase contract or before construction starts. With new-build investments this is the most common mistake: buyers sign the purchase contract before the application is through — and the funding is gone. I make sure the sequence is right.

KfW 297 vs. KfW 298

KfW 297 applies to owner-occupiers, KfW 298 to investors/landlords. Both programmes offer up to €150,000 per residential unit and a repayment subsidy of up to 25%. The interest rates are well below market terms — typically 0.5–1.5% below the best bank loan.

Combination with §7b special depreciation

A QNG new build combines KfW 298 with §7b EStG (5% special depreciation over 4 years) and declining-balance depreciation under §7 (5a). For investors at the top tax rate this results in up to 38.5% depreciation over 4 years — on top of the favourable KfW loan.
