Make 8-10k/ month but can't quality for FHA

[Johansen Sanchez]

I work as a Dental Hygienist in NY. Have been working all through school and landed my career job a year ago. First 6 months was paid hourly, since Jan 2018 have been on straight commission pay. Have tried multiple banks and lenders but nobody will approve me for a loan. I have great credit, barely any debt, make 8-10k per month. How do I get an FHA owner occupied 4 unit without waiting 2 years or putting 20% down?
