If you are thinking about buying a holiday home, second residence or investment villa on Kenya's South Coast, this is a long, plain-English guide to what you actually need to know — written by the people who design and build them. Take fifteen minutes; it will save you ten meetings.
Diani Beach is a 17 km uninterrupted stretch of reef-protected white-sand coastline on Kenya's South Coast, in Kwale County, about an hour's drive south of Mombasa International Airport (MBA). It is the most established second-home and small-resort destination on the East African coast, sitting between the Tiwi River to the north and Kongo River / Galu Kinondo to the south.
Within Diani, the two stretches that matter most for residential buyers are Diani Beach proper — the central, more developed strip with hotels, restaurants and beach access roads — and Galu Kinondo, the quieter southern end where new residential development is concentrated. Galu is where DIA Development builds, and where most of the new boutique residential supply has come online over the past five years.
Practically: from Ukunda Airstrip (5 minutes from Galu) there are daily scheduled flights to Wilson Airport, Nairobi, on Safarilink and AirKenya. From Mombasa International there are direct flights to Frankfurt, Zurich, London, Doha, Dubai, Addis Ababa and Johannesburg. Door-to-door from most of Europe is under twelve hours.
Three structural shifts have, over the past five years, made Diani materially more reachable, more livable and more investable than it has ever been before:
The completion of the Standard Gauge Railway (Nairobi–Mombasa) in 2017, the opening of the Dongo Kundu bypass in 2024–25, and the upgrade of the South Coast Highway have collectively cut the road journey from Mombasa Airport to Diani from 2 hours to under 60 minutes. Reliable fibre internet arrived along the coast in 2022. Power and water reliability in residential pockets like Galu has improved every year.
Where ten years ago Diani's residential building was largely informal, today the South Coast has a settled community of architects, engineers, quantity surveyors, tradespeople and finishing specialists working to international standards. DIA Development is part of this generation. The result is that international buyers can now expect the same standard of construction documentation, milestone payments, defects period and handover dossier they would receive in Spain, Portugal or the UAE.
The pre-2020 image of Diani as a December–January destination is outdated. The two long high seasons (December–March and July–September) are bookended by an increasingly busy April / June / October / November shoulder, and remote-work residency and digital-nomad presence has flattened the curve further. Holiday-home owners are arriving for two to three weeks at a time, four to six times a year, rather than once at Christmas.
Diani is a small, supply-constrained market. There is no glut, no overhang, and no large-scale apartment developer presence comparable to what you see on the Northern Mozambique or Pemba coasts. Most residential supply is brought to market by small, often family-run developers building 4–10 units at a time in walled compounds.
Indicative price bands as of 2026 for new-build, ready-to-occupy holiday homes in Galu Kinondo and central Diani:
Land alone, in good Galu locations, currently trades between KES 6m and KES 25m per acre depending on access, road frontage and proximity to the beach.
Annual price growth in well-built coastal residential has averaged 5–8% over the past five years, materially outpacing Kenyan retail inflation. The driver is supply scarcity in the <EUR 500k bracket, not speculative demand.
DIA Development has seven units across two active developments currently for sale in Galu Kinondo, from EUR 179,000.
Under the Constitution of Kenya (2010) and the Land Act, foreign nationals and foreign-owned companies cannot own land in Kenya on freehold terms. Freehold — perpetual ownership, unlimited in time — is reserved for Kenyan citizens.
What foreigners can hold is leasehold, with a maximum lease term of 99 years. A 99-year leasehold is, for all practical purposes during the lease, equivalent to ownership: you can build, mortgage, sell, inherit, lease and rent out the property. The lease runs from the date of grant, and is renewable at the end of the term subject to government policy at that time.
Two routes for international buyers:
Both routes are routine and well-understood by Kenyan advocates. We can introduce trusted advocates who handle both for international buyers every week.
Beyond the headline price of the property, a buyer in Diani Beach typically pays:
On a EUR 250,000 villa, the total acquisition overhead beyond price is approximately EUR 14,000–16,000 (i.e. ~5.5–6.5% of the price). On a EUR 179,000 bungalow, ~EUR 10,000–12,000.
VAT does not apply to residential property transfers in Kenya. There is no separate property purchase tax for foreigners (the 4% stamp duty applies equally regardless of buyer nationality).
Kenya levies Capital Gains Tax on the disposal of property at 15% of the net gain (sale price less acquisition cost less qualifying improvements). The tax is settled at point of transfer through the buyer's advocate. Improvements documented during the build phase are deductible, which is one of the reasons we maintain a comprehensive handover dossier — it is materially worth the few hours required to review and file it on receipt.
For a 2- or 3-bedroom DIA Development home held purely as a private holiday residence — i.e. not rented commercially — total annual running costs typically sit in the region of EUR 4,000 to EUR 8,000 per year all-in, depending on caretaker arrangements. Indicative breakdown:
If the home is rented commercially (Airbnb, agency, direct), expect income tax of 7.5% on gross rental receipts under Kenya's residential rental income regime, plus the booking platform's commission and a managing agent's fee of typically 15–25% of gross.
For a typical reservation-to-handover purchase of a new-build DIA home, the calendar looks like this:
Roughly half of DIA Development's buyers to date have been continental European (German, Swiss, Austrian, Dutch), about a quarter have been UK and Irish, and the remaining quarter has been a mix of Kenyan-resident expatriates, Middle Eastern and South African buyers. Almost all are second-home owners first, investors second — the home is bought to be used four to eight weeks a year, with occasional Airbnb let-out covering a portion of the running costs.
The typical age range is 40–65, often a couple. A growing minority are families with school-age children doing a 4–8 week stretch in Diani during the European winter as part of a year-round travelling-family lifestyle.
