INSERT INTO houses(house_id,hname,howner,hpass,x,y,z,a,cpx,cpy,cpz,hint,hvalue) VALUES(0,'House For Sale!','INVALID_PLAYER_ID','INVALID_HOUSE_PASSWORD', %0.2f, %0.2f, %0.2f, %0.2f, %0.2f, %0.2f, %0.2f, %d, %d)", X, Y, Zp, (180.0 + Angle), Xp, Yp, Zp, interior, cost);

Why are you setting the house ID as 0, do you have AI enabled for house id on MySQL DB/PhpMyAdmin?
