Its never Dumb to ask questions the more you ask the better informed you become!! and hopefully you won't end up buying a pig in a poke, unless you want one of course

Never trust an estate agent they are working for the seller!!
Get your own solicitor!!
Don't buy without a Cedula unless you want to camp in a barn!!
There are people selling who will do all white money!!
Don't believe anyone who says water and electricity close by and easily obtained!!
If you can't find evidence on the esquitura of the words vivienda don't buy!!
And look for the date of construction before 1984!!
Unless of course it has legal permissions to build very rare!!

Mind you as Jools says you will probably ignore everything you have been told and buy with your heart instead of your head

Ahh well ::) ::)
