Do you also help finance real estate for commercial purposes (such as a B&B)?
Financing in Spain of a Bed&Breakfast or commercial property
Yes a mortgage can also be arranged for these purchases, but again the same mortgage criteria apply as all other property purchases in Spain. That is, there is a minimum purchase price, the age applicant does not exceed 65 and the income requirements of Spanish banks are met.
In addition, for a Bed&Breakfast, people often look at a Rustic property (in the countryside), which banks in Spain are generally not eager to finance. You can read more about this in the article Finca Rustica vs Finca Urbana.
Note: for commercial property financing are expected revenues NOT included in the mortgage application. The purchase is equivalent to a purchase for private use and thus the requirements for income or assets are the same. Both for Spanish banks and in culture, it is not customary to look to the future for your application, but your history and the present.
