Current average purchase price per m² for houses in Oy: 4,850 €/m²
House prices in Oy have risen significantly over several years — driven by its proximity to Munich, high demand for family-friendly home ownership, and limited supply. Strong increases until 2022 were followed by a slight correction in 2023/2024, before the market recently showed renewed strength.

Current average land value per m² in Oy: 430 €/m²
The land value in Oy has developed significantly upwards — a reflection of the quality of the location and its proximity to the Munich market. Plots are scarce, and demand is structurally high. Strong increases until 2022 were followed by a brief consolidation before values stabilised.

The property market in Oy-Mittelberg can generally be classified as having limited supply and stable value. On the buyer side, the market is dominated by owner-occupiers, regional households with high residential standards, and those interested in holiday and second homes. On the seller side, relatively few listings meet consistent demand, which supports price levels. The market thus shows characteristics of a seller's market, even though increased financing costs since 2022 have dampened momentum somewhat. For buying a house in Oy-Mittelberg and buying an apartment in Oy-Mittelberg, the following applies: location, condition, energy efficiency, and plot quality influence the achievable price to an above-average degree. Demand remains robust, especially in well-connected, quiet, and scenically attractive locations. For capital investors, Oy-Mittelberg is interesting because rental demand is stable and vacancy risks remain limited in good locations. The rough gross rental yield range is usually around 2.5% to 4.0%, depending on property quality, micro-location, and price level. Compared to urban centres, yields are slightly lower, but value stability in high-quality locations is often higher.
Anyone wishing to make a sound assessment of the market in Oy within the Bavarian market, with its strong ties to Munich, should take a look at the multi-year price development. For detached and terraced houses in Oy, the average purchase price moved from 2,950 €/m² in 2017 to the current 4,850 €/m² (2026) — a total change of +64.4% over 9 years, which corresponds to an average value increase of +5.7% p.a. Condominiums in Oy started at around 2,650 €/m² in 2017 and are now at 4,250 €/m² (+60.4% over 9 years, Ø +5.4% p.a.). They are therefore often suitable as an entry point into home ownership or as a capital investment with a manageable ticket size. The average net cold rent in Oy developed from 7.90 €/m² (2017) to the current 11.80 €/m² — +49.4% over 9 years or Ø +4.6% p.a. For landlords, the continuous rent increase ensures a predictable adjustment to inflation and operating costs. The standard land value (Bodenrichtwert) in Oy rose from 180 €/m² (2017) to the current 430 €/m² (+138.9% in 9 years) — a key indicator of structural location quality and local demand for building land. Based on current values, a rented condominium in Oy yields a calculated gross rental return of around 3.3% — without taking into account vacancies, maintenance, and ancillary purchase costs. Experience shows that realistic net yields are 0.8 to 1.5 percentage points lower. With around 4,500 inhabitants, Oy forms a comparatively narrow market segment — which means: well-prepared properties priced in line with the market are usually sold quickly, while overpriced offers remain on the market longer and lose negotiating room. For owners in Oy considering a sale or letting, an individual, data-based valuation is the most important first step — it replaces estimates from online calculators, which cannot reflect micro-location, energy efficiency, and property substance. FREITAG® provides this valuation free of charge and without obligation.
Rental yield range (approx.): 2.5 – 4 % gross.

Frequently asked questions about buying, selling, financing, and living in Oy — concisely answered.
Many owners in Oy are sitting on an asset that they cannot access because they do not want to give up their home. This is precisely whatProperty annuity (Immobilienverrentung) is for: The sale takes place, but the move-out does not. Depending on the model — Usufruct, Right of abode, Life annuity or Leaseback — the purchase price is paid as a lump sum, as a monthly annuity, or as a combination of both.
Security is crucial: The right of abode (Wohnrecht) is entered in the land register (Grundbuch) in the first rank, before the buyer is registered as the owner. We will calculate for your property in Oy how much the usufruct (Nießbrauch) value reduces the purchase price — and whether this is more profitable compared to a traditional sale.
We approach this with an open mind. If a normal sale with a subsequent move is economically better for you, we will tell you — instead of trying to sell a property annuity (Immobilienverrentung) model that doesn't suit your needs.
For production halls, office buildings, medical centres (Ärztehäuser), and logistics areas in Oy FREITAG® brokers both classic sales and Sale & Lease-Back. Buyers include family offices, real estate funds, and private portfolio holders with a long-term horizon.
The process is discreet: contact is made off-market, without an advertisement and without a sign on the property. Employees, customers and competitors in Oy will not know anything, as long as you don't wish it.
It starts with a reliable valuation based on the income approach (Ertragswert) — not a desired figure. Based on this, you decide whether to sell, lease back, or hold.
Owners of hotels and restaurants in Oy who wish to sell their hospitality property or lease it want, will find FREITAG® to be a partner for the Horeca sector. We broker everything from traditional guesthouses and cafés to hotels and boarding houses to investors and successors who understand the industry.
Selling a hotel in Oy without business interruption is a complex task: We assist with valuation, discreet exposé creation, and approaching suitable buyer groups — for ongoing operations as well as for properties with conversion potential.
Alternatively, we lease: solvent tenants with industry experience, checking of creditworthiness and concept, long-term predictable lease income. For every hospitality property in Oy the right strategy.

Plot layout, building fabric, maintenance backlog, and neighbourhood determine the price. We objectively assess these points and align the marketing accordingly.
Whether rented or vacant: We assess which buyer group is realistic for your flat, and consistently align the exposé, price, and approach accordingly.
A plot of land sells based on what can be built on it. We determine the realistic building rights and approach property developers and private buyers in parallel.
Valuation based on the income approach (Ertragswert), review of rental agreements, and targeted approach to portfolio holders and family offices — without public advertising.

The right rental price determines whether a property stands vacant or has long-term tenants. We set it at a market-appropriate level and pre-filter interested parties, instead of holding mass viewings.
From defining the ancillary costs arrangement to the handover: We structure the letting of your house in such a way that no disputes arise later.
Right of residence (Wohnrecht), leaseback, life annuity (Leibrente), or usufruct (Nießbrauch) — we examine the most suitable option for you and advise on opportunities and framework conditions.
For inheritance disputes, divorce, banks or sales — a reliable valuation that stands up to scrutiny from third parties.
Contact us — we will advise you without obligation on valuation, marketing, and next steps.
