Switching part time to full time

[Julian Riezgo]

I just graduated college and start a job soon that is directly related to my degree(Since banks count college as "job experience" so long as the job and degree are related to each other)

I have about 70% of a downpayment saved up for an investment property. I want to work part time to free up time to look for deals and also retake some classes online for my future schooling. If I worked part time, would I still be able to qualify for a loan even when I have all the cash in my checking account?

My thinking is what if I work part time for let's say 4 months, and then if the bank wants 2 months of pay stubs, just switch to a full time position at the same job for months 5 and 6.

Is that a thing? I've tried looking into this and I can't find anything
