Which other countries do you guys think of worth checking to buy a property for the purpose of getting rent and buy your rent in CH? sure, neighboring countries like Italy, Germany etc to consider but what other countries do you guys make sense offering good value in this current environment?
I'd say any other country where you have a network of people who can contribute to make it a successful business. So, a notary, a lawyer, a plumber, an electrician, etc. It doesn't hurt if you have a passport from there. Covid showed us that home ownership was not enough to travel there during the time with hardest restrictions.
Or, real estate investment funds, what Enohzee mentioned.
As for the OP, how long is a piece of string- just depends on so so many things. Portugal is very popular at the moment, but whether is it right for OP, who knows?
