Morttgage Payment Issues

Hi All,

I bought an off plan leaseback in Normandy in 2010. Unforunately the builder has gone bust and the leasback company with it. This after having drawn down 80% of my mortgage but completing none of the building works. So I have been left with a mortgage effectively on a plot of land with no sight of any rental income. I am seriously considering not paying the mortgage but am worried as do have property assts in the Uk. Has anyone else simply stopped paying the mortgage and have they been legally chased?

Thanks

Paul
