I have had steady employment except when I took a break from work to focus on school. Less than a year later, I re-entered the workforce as temp to perm for 3 months and then full-time permanent. How long do I need to wait to apply for a home loan or do I need to wait at all?

you should be Ok as long as the present full time job is not all commission position ...did you get a degree from the education / school you mention ....are these jobs are simialr in nature ?? .a good letter of explanation will be helpful as well ....get pre approved with a loan officer so you can know for certain
