San Juan, La Unión, Cartago real estate: investing guide

Overview

San Juan, La Unión, Cartago real estate covers the third district of the canton of La Unión, in the province of Cartago, Costa Rica. It spans 3.9 km² (1.5 sq mi) and uses postal code 30303. The district is small and sits inside the Central Valley, away from the coast.

Buyers here find houses, apartments or condos, lots and farms. Because the district is compact, the choice often comes down to which type of property fits your plans and how much work you are ready to take on.

What people buy here

The mix of listed property supports several buyer profiles. Someone who wants a home to live in can look at houses or apartments and condos. A buyer who plans to build can compare lots and land. Farms suit those who want more open space and are prepared to manage it.

Buying to rent is another path. Houses and apartments are the types that tend to be rented out, so a purchase of either can become long-term investing if you plan to earn rental income later. When there are enough listings, this page shows above what is listed by type and typical prices, which helps you compare options before contacting anyone.

Property types

  • Houses: check the condition of the roof, walls and plumbing, and whether the built area matches what is registered.
  • Apartments or condos: ask about monthly fees, what they cover, and the building rules.
  • Lots and land: confirm legal access, the shape of the terrain, and whether water and electricity reach the boundary.
  • Farms: look at access, water sources, the state of any buildings, and what the land can legally be used for.

Why buy here

San Juan is close to several reference points. The canton seat, Tres Ríos, is 2.0 km (1.2 mi) away in a straight line, and downtown San José is 7.5 km (4.7 mi) away in a straight line. Juan Santamaría International Airport (SJO) is 24.0 km (14.9 mi) away in a straight line.

The district is not coastal, so there is no beachfront land to consider. It belongs to the Central Valley region, in the province of Cartago, which matters for the highland climate and the usual rainy and dry seasons of that part of the country.

What to check before buying

  • Run a title search at the National Registry (Registro Nacional) to see who owns the property and whether it carries mortgages, liens or annotations.
  • Ask for the registered survey plan (plano catastrado) and compare it with the title and with the boundaries, size and access you see on the ground.
  • Request a land-use certificate (uso de suelo) from the Municipalidad de La Unión, plus the canton's zoning plan where one exists, to learn what can be built.
  • For lots or farms, get written water availability from AyA or the local ASADA, confirm electricity, and check protection areas around springs and rivers (Forestry Law 7575).
  • For apartments or condos, read the condominium bylaws and get proof that fees are paid (Law 7933).
  • Confirm property tax (Law 7509) and municipal services are current.

Getting around

San Juan borders six districts: Sánchez (canton of Curridabat), Tirrases (canton of Curridabat), Tres Ríos, San Diego, Concepción and Río Azul. That puts it in a built-up part of the Central Valley, with several neighboring districts nearby.

Official neighbourhoods in the district include Araucarias, Danza del Sol, Herrán, Loma Verde, Unión and Villas de Ayarco. Real travel time depends on the hour and the road, so test the routes you would use at the times you would use them before you decide.

How to buy

A purchase usually starts with comparing several properties and their asking prices. A local agent can help with that and with access to owners. Agencies and agents with listings in the zone appear further down this same page.

The transfer is done by public deed before a Costa Rican notary, and it pays the transfer tax (Law 6999). Ask for the full closing-cost breakdown before signing. Foreigners can own titled property in Costa Rica with the same rights as citizens (Article 19 of the Constitution), with the exceptions the law sets. Before investing, have the title search and survey plan reviewed before you pay a deposit.
