I heard it looks more stable income if you create a business LLC and then connect a business checking account to it. Then just schedule regular self paying withdrawals around the same amounts. Creates a stable trail of income on paper and makes you look more professional but haven’t tried it yet myself.

Ya just do manual verification and make sure you select regular deposits at the highest amounts

mortgage companies will do mortgages for self employed borrowers with Bank statements.

Keep a paper trail and file taxes

File a 1099 make sure you deposit the money into a new Bussiness account to prove you have a gig job that pays regular
