In order to better assist you in a search, we need to understand what category it fits. In fact, the criteria to be refined in order to target research clearly implies that the main objective pursued is clearly stated beforehand.
This will depend on your own location, but also on the conditions of access (distance, ease of travel, visa or not), taxation and exchange rate conditions prevailing in the area sought after, the equipment of the targeted region, the security of premises, legislation on real estate investments for foreigners and/or non-residents, etc.
The choice of a specific destination, based on the criteria listed in the list above (or more personal ones), is a prerequisite for conducting effective targeted research.
Before engaging in an active search based on the criteria defined for the aspects listed above, it is also necessary to investigate further the targeted market, to evaluate the type of property that you will be able to acquire according to the total budget that you have decided to allocate to your investment (both down payment and + mortgage loan).
This step should include the costs related to the acquisition in itself (notary fees, taxes, travel, and living expenses), then, if it is to modify a property, or renovate it heavily, or to build on an adapted site, to add the expenses of architect, direction of building site, of works and equipments, of decoration / furnishing, of garden, creation of swimming pool (villa), of roadworks if necessary, or still connect to existing networks (making sure they are available, including available power ... mainly). This is to ensure the accounting of the results obtained with those of your budget. Of course, these elements will vary greatly according to the preferred location for the investment. For example, the purchase cost per square meter of an old castle in the countryside in France will be around at 10.000 / 15.000 € / m2. While for a villa of two or three bedrooms in St Barthelemy we will be rather to 15.000 / 20.000 € / m2 ... But significantly less in Bali or Thailand.
