loan - anwar azam khan

Hi all.

Just looking for a quick piece of advice. I recently got a 100% mortage for a property ive been in for about 4 months.

Is it possible for me to get a secured loan on it if i have a 100% mortgage?

Also..........if you take out a secured loan........does it mean you can seel your house and buy another one during the time of the loan period?

Sorry if these questions are a little dumb.........just really unsure of this sort of thing and was told the advise on here is first class.

thanks all.
