I live in an apartment in new york city.  It is a self contained housing unit on a single level.  I miss a garden though.  What kind of property do you live in?
I live in a house in the suburbs, how is the quality of life in New-York ?
Its ok.  It is a busy, thriving place but an apartment is all I can afford.  I sometimes think I should look into the affordable housing scheme where there is help to get a property from the government 
How much would you save if you lived in a affordable housing appartment ?
Not too sure but the literature states that it helps with mortgages and recognises a persons affordability index.   
You would be the owner of your appartment ? That would be great, but the taxes would be high, you would get financial aid for that ?
Some.  In australia it is a much better scheme. It is worked out that payments do not cost too much so that a householder can meet the basic needs easily. I have always thought of moving to australia maybe now is the time!!
