Feel free to contact me if I can be of any further assistance. Good Luck!
Every lender I have dealt with has wanted you to at least start the job befor closing and many want you to get the first paycheck. July is not that far away start the house hunt and plan on a July closing
Good Luck and Congatulations on the job
To qualify for a mortgage, you have to demonstrate the ABILITY to make the payments. If you start working in July, you likely won't begin getting paid until late July/early August. For now, you probably wouldnt be able to get a loan unless you had a qualified co-signer, however if you are looking at homes closer to your start date you may have a better chance.
Best of luck
