just to point you in the right direction

What you can do is make a function that sends an item to 1 1 10 <map here>
foritems 7648 (i think thats the map size)
if (<basid>==i_multi_'house type'>) || (<basid>==i_multi_'house type'>)
remove
endif
endfor

anytime im doing massive item removal i do a function similar. above is just a basic idea of what you want to accomplish. hope that helps
