ULTIMATE "CONCRETE GOLD EGG-LAYING WOOL MILK PIG INVESTMENT"
FACT: A target-market-tailored, turn-key furnished apartment in a prime city location as an investment is absolutely unique. It optimizes one of the last legal tax havens (real estate depreciation) into leveraged, double-digit yields that are automatically increased every year. Yields are more than double the long-term benchmark yield of stock investments (MSCI = 7%), while exhibiting zero volatility and minimal “concrete gold” risk. PLUS the long-term guaranteed appreciation of a prime property. In short – it’s THE ultimate investment for tax-optimized wealth accumulation and retirement planning. In a nutshell – THE standalone “Concrete Gold Egg-Laying Wool Milk Pig Investment”!
PROBLEM: The rental price cap tightening already approved by the federal cabinet and coming into force at the end of the year will make furnishing and profitable furnished rentals impossible in the future.
SOLUTION: The purchase of an already furnished and rented apartment with unassailable, statutory rent protection (according to § 556e Abs.1 BGB).
OFFER: In the very central city location of the increasingly in-demand Belgian Quarter among the core target groups, on the 2nd and 3rd floors of a modernized building from the 1950s, four fully furnished, turn-key smart home studio apartments are for sale. Units 9 and 18 are currently rented, unit 10’s rental period is expiring, and unit 16 is vacant. All come with the aforementioned statutory rent protection. Units 10 and 16 are additionally suitable for owner-occupancy (e.g. for parents with children in vocational training or university).
Through rent and tax advantages, you can achieve capital yields of up to an effective 19% (pre-tax yield according to the profit and loss statement compared to other investments).
After deducting all costs, interest, and repayments, a four-digit surplus remains, which continuously increases with index/step rent adjustments.
PLUS the secured appreciation of the prime property. PLUS the generous rental reserves at consistently higher prices than the competition. PLUS the tailwind of the tightened rent control, which cements the uniqueness and future security of your investment in “golden concrete.”
