I’m self employed so I try to pay as low in taxes as possible.For additional income I recently started to house hack my primary home (4bed 2bath) I am currently house hacking renting 3 room each per month to international students for $650. 

So I am trying to close on my first home, and have been getting a couple of offers of employment for the past couple of months that are significantly higher pay than what I am making right now.
