Did short sale 2 years ago...wanting to buy..need advice?

Did a short sale with a hardship...hubby lost job and we had to move for new one. Now I really want to settle down. Have paid down most of debt got scores to 690's but he became unemployed again so I took out a loan to consolidate payments of his personal debt and watched my scores plummet. WHat the heck? I make well over 6 figures and have saved about 10% of house type I desire in 2 years...have been steadily employed and am considering making a move for a promotion but won't do it if I can't buy...any advice? We have no children and can easily live on my salary. My debt to income ration is <30%
