You have a tricky case for sure. Most Underwriters will be looking for a 24 month work history for any borrower today. Having said that, you are a text book example of the type person I have been able to help over the years. I assume at some point you had a previous job or career? And if so, you should have a least a 14 month previous work history?
All we require is proof that you had gainful employment prior to your maternity and the new job can be tied together, meaning you are in the same type of industry. It would really help seal the deal if you were on salary not hourly. If you are paid hourly you could be income averaged over the 24 months unless you can get a "At-A-Girl Letter". Something like:
To whom it may concern,
Although Mrs Smith has been with this company a short time, she has proven herself to be a valuable, trustworthy, and reliable employee. She is currently employed as a ______, and she is required to work a minimum of 40 hours a week. Her continued employment is excellent.
With a strong letter from the employer, I am sure can get a home loan having been on your current job less than a year. As far as credit, we and some other lenders do not require a minimum amount of tradelines reported on your credit, but do require a minimum 620 middle credit score. Inquiries are immaterial and can be explain as you have been shopping for home loan.
Hopefully this information has been helpful.
Best of Luck!
