I want to make 
everybody aware of how you can get caught out. The sales man tells you that you will be offered a 
guaranteed rental agreement after completion
which will cover your mortgage repayments. He also says that you will
be able to sell 'Off plan' and make money so you don't need to worry
about getting a mortgage. In reality the 
gauranteed rental
is not enough to pay the mortgage and you can't sell because the
developers are still building and have plenty of apartments for sale
themselves. It means you get left with mortgage repayments you cannot
keep up or even worse you can't get a mortgage and 
loose the 30% deposit you paid.
Please be aware and get any promises
 in writing so you do not loose your money.
