Owning your own home

Difficult to get a loan for - few lenders; difficult to get a mooring of any length in London; expensive mooring fees; depreciating asset with expensive maintenance costs; sea sickness....

They not perfect but no solution is. You can buy them from about 12-15k so most people should beable to save at least a few grand over a few years and then get a loan for the rest if need be. The girlfriend sister just moves ever 2 weeks during the summer, stays put in the winter, simple. Maintenance is the biggest issue but everything has maintenance and I hope you are joking about sea sickness.
