While popular expat hubs like Puerto Vallarta and the Riviera Maya grab most of the attention, a wave of foreign residents is looking at Mexico's second-tier cities and coastal towns — places with colonial character, decent infrastructure, and price tags that haven't yet caught up with the famous names. Here are the spots gaining traction.

Mérida, capital of Yucatán, is arguably the one closest to going mainstream. It offers authentic Yucatecan food and culture, well-kept streets, strong services, and direct flights to Mexico City and the US — plus easy access to Maya ruins, cenotes, and restored haciendas. The catch is climate: winters from November to March are lovely, but spring and summer highs hit 40-45°C, making it one of Mexico's hottest cities. Many residents simply overwinter and leave in the heat.

In the central highlands, Guanajuato is a steep, mountain-ringed colonial capital about 90 minutes from San Miguel de Allende. It's beautiful and seeing growing foreign investment, though its narrow alleys and hillsides demand decent fitness. Nearby Querétaro is a different proposition: a booming, pristine colonial city within easy reach of Mexico City, drawing both Mexicans and foreigners with jobs, prosperity, and a growing wine scene. Its weekend-getaway neighbour Tequisquiapan could be next.

Michoacán's pairing of elegant Morelia and indigenous-rooted Pátzcuaro has stayed under the radar, helped recently by direct US flights to Morelia and a fast toll road from the capital. The bonus: you can drive to the Pacific at Ixtapa-Zihuatanejo in under four hours when mountain winters bite.

On the coast, Mazatlán is emerging as a value pick on the Pacific — cooler than southern beaches, affordable, close to the US, and seeing serious infrastructure and real estate investment. Further south, Manzanillo is even less discovered: a working port town with a laid-back feel, split between resort bays and a downtown core, and among the cheapest coastal property markets in the country compared with Los Cabos or Puerto Vallarta.

Oaxaca City, often called the soul of Mexico, offers a temperate highland climate, a gorgeous historic centre, and nearby sites like Monte Albán and Mitla — though the Pacific at Huatulco or Puerto Escondido is a long mountain drive away. And for something more exclusive, Tepoztlán near Cuernavaca sits in a dramatic valley with a mystic, New Age-tinged reputation. It's pricey to buy or rent, but has a small, well-established foreign community and an easy run to Mexico City.

The common thread is choice: whether you want colonial streets, beaches, mountains or wine country, there's now a credible option outside the established hotspots — often with better value and a lighter concentration of foreign residents. For travellers, most of these places work equally well as extended-stay destinations or scouting trips for a future move.
