What you say ,could well be the case and because I do not know your circumstances and I cannot see into the future .I would recommend that you take the loss and play safe
My circumstances would allow me to hold on and enjoy and wait ,because a place in the sun is pure pleasure,and if it never sold it would not matter.
The other -side of the coin,my friend bought as an investment on a mortgage ,and he/she expected the value to rise and to rent meanwhile.
Historically property prices rise long term ,can you avoid to wait and just enjoy meanwhile .,but if it makes you miserable because it is eroding your standard of living sell.
The same situation for my UK home,I enjoy the location and the neighbours are good ,so treat it as a home not an investment.
