We just have to put the medicine cabinet in the bathroom and install the light fixture in the first apartment that is almost ready,  We have advertised the apartment for $1,000 and have gotten some response but no one has come to see it yet.  

There's a reason that certain profession, like medicine, law, and real estate appraisal are regulated by the government, because when they are performed by someone without the proper training there can be bad consequences.

Just got my 1099 for last year and those fees (to which we never received) were included (even the $1 ACH fee they collect).

@Hjiorst FjioordsHere are considerations in choosing a Solo 401k provider and bank to provide the account:Solo 401k Bank Account Considerations:Here are some general considerations:If you want access to bank checks, a debit card and/or the ability to ACH funds out, you will need a bank, credit union etc. rather than a brokerage.There are 100s of banks and credit unions that have opened accounts for a Solo 401k.Keep in mind that the bank's role is limited to simply providing the account (i.e. no tax reporting, no recordkeeping, etc.) such you may wish to de-prioritize familiarity with Solo 401k plans and focus on other things that are important to you (i.e. branch locations, fees, etc.).If you want the ability to invest in stocks, mutual funds, etc., you will need a brokerage account.Many brokerage firms will open "free" accounts (i.e. no setup fee, no maintenance fee), which will also come with checkbook access and the ability to wire funds out such that they function as a "hybrid" between a bank and/or brokerage account.If you are looking for names of banks that open bank accounts for Solo 401k plans, there are many banks where we have received positive feedback including Wells Fargo, Bank of America, PNC along with local banks and credit unions just to name a few.

Can anyone give me some recommendations, or banks/credit unions that have caused them head aches?

I am also a physician and RE investor and think it's great that you are looking at options outside of medicine to build your wealth.
