Build vs buy a house in Costa Rica: a 2026 guide for overseas buyers

Buy an existing home if you need to move in within months, want a known price, and can find a well-built house in the right spot. Build if you want a specific design, a better lot, or modern construction, and you can wait for design, permits and 5 to 8 months on site. In 2026 a new build with Decentra costs about $1,000 to $1,200 per m2 for an upper mid-range finish and $1,500 to $1,800 per m2 for luxury, before land.

We are a design-build company in Guanacaste. We build new homes and we renovate existing ones, so we work on both sides of this decision. Here is how we would think it through. This guide is general information, not legal or tax advice; confirm closing costs and taxes with your Costa Rican attorney or accountant.

Build or buy at a glance

What buying an existing home really costs

The purchase price is only the start. Closing costs for a straightforward residential purchase run roughly 3.5 to 5% of the price (Tico Times; RE/MAX Costa Rica). That covers:

• Transfer tax: 1.5%, charged on the declared sale price or the registered fiscal value, whichever is higher.
• Stamps and National Registry fees: roughly 0.5 to 0.8%.
• Notary fees: generally 1 to 2% of the price, following a schedule set by the Colegio de Abogados.
• Escrow: about 0.25% or a flat fee near $1,000, if you use a registered escrow agent.

One 2026 change older guides miss: the 20% reduction in transfer tax and other incentives under Law 9996 expired on July 14, 2026 (Tico Times). Budget for the full 1.5%.

Then come the repairs. Existing homes, especially older ones, often need some of this work:

• Roof leaks and poor drainage that show up in the rainy months
• Termite damage in wood ceilings, doors and trim
• Corroded steel, railings and fixtures near the ocean
• Mould from poor ventilation
• Old wiring and plumbing, or a septic system that is too small
• Rooms, decks or pools added without a permit

That last point matters more than buyers expect. If a past owner added a room without permits, the house on the ground does not match the registered plans. That can slow a resale or block the permit for your own remodel later. Ask for the permit history and compare it with what is built before you sign.

If you buy, plan a renovation budget from day one. Our renovations page explains how that work is handled once the house is yours.

What building a new home really costs

These are Decentra's 2026 construction figures, before land:

Add to that:

• Design and plans: about 5.5% to 6% of construction value, under the CFIA fee schedule.
• Contingency: 10 to 15%.
• Pool: about $2,500 per m2 of pool, all in (excavation and grade work, the shell, the finish and filtration). Lighting and custom features add to that.
• Land: the purchase price, plus the closing costs above on the land deal.
• Studies: a topographic survey and a soil study, paid separately.

A worked example: a 350 m2 home at an upper mid-range finish of $1,000 to $1,200 per m2 is $350,000 to $420,000 in construction. Design adds about $19,000 to $25,000, and a 10 to 15% contingency adds $35,000 to $63,000. Land and closing costs come on top. For the full breakdown, read our cost to build a house in Costa Rica guide.

For Decentra new builds: Minimum construction budget $350,000 USD, before land. This does not apply to renovations.

Time: how long each path takes

Buying is faster. Once you find the right house, the purchase itself is a matter of weeks to a few months, depending on title checks and how you pay.

Building takes longer. First comes the lot work, then design, then permits, then 5 to 8 months on site for a typical Decentra home. Permit times depend on the municipality, and some are adding steps. In the Osa municipality, for example, a new review procedure applies to land-use applications submitted after June 15, 2026 (Osa Tropical Properties). Our guide to how long it takes to build a house in Costa Rica breaks down each stage.

The lot decides more than the house

When you buy a house, the hard land questions were answered, or ignored, by whoever built it. When you build, you answer them yourself. Before you buy a lot, check:

• Water: a water availability letter from the local provider. Without it there is no building permit. See permits and water letters.
• Zoning and setbacks: what the municipality allows on that lot, and how much of it you can build on.
• Soil and slope: a soil study and a topographic survey tell you what the foundation and grading will cost. On steep lots, retaining walls and drainage can move the budget a lot.
• Access and power: road access in the rainy season and the distance to electricity.
• The maritime zone: the first 200 meters inland from the high tide line belong to the state. The first 50 meters are public. The next 150 meters are a restricted zone where the municipality grants concessions, not title (Tico Times).

Foreign buyers can own titled property in Costa Rica with a valid passport. No residency or local partner is needed (Tico Times).

We check lots for clients before they buy through our land and construction consulting.

Taxes after you move in

Both paths carry the same yearly taxes once you own the home.

• Municipal property tax: 0.25% of the registered value each year (RE/MAX Costa Rica; Tico Times).
• Luxury home tax (impuesto solidario): for 2026 it applies when the value of the construction and fixed installations is above ¢143,000,000. Rates run from 0.25% to 0.55% in brackets, and payment for each year is due by January 15 (EY; AG Legal). Tico Times put the threshold at about $318,000 at the September 2026 exchange rate.

This matters for new builds. A new home can pass the threshold, so check the likely valuation with your accountant from the start. Owning through a company does not exempt the home (AG Legal).

When buying makes more sense

• You want to live in Costa Rica within the next few months.
• You found a well-built home in the right spot, with clean permits.
• The area you want has few good lots left.
• You would rather renovate one or two rooms than manage a full build.

When building makes more sense

• You want a layout, view or size the market does not offer.
• You found a great lot, or you already own one. Our guide to building on your own land covers that case.
• You want current construction: a concrete structure, modern waterproofing, efficient glass and new systems.
• You plan to stay for many years and want the house to suit you.

A third option: buy and renovate

Good value often comes from a solid home in a good location that needs work. The structure and the lot are proven, and you change the parts you dislike. The risk is the same as any purchase: you need to know what is behind the walls before you buy. Have a builder or engineer look at the structure, roof, drainage and permit history first.
