@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.

We filed jointly and our income property is in both of our names.

I would go with cheap Male/Female or any sex large rooms, with a joint bathroom and kitchen area. 

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

The easiest way to make this work if you have a regular W2 that you don't want to quit is to have a spouse that doesn't work and file a joint return.

Joint venture.

His training is focused on buying single family houses with joint venture partners and then selling the houses on lease options.

This is expansion joint so as the ground heaves or thaws the road and the building pad move separately.Below is our existing office front. 

My thinking was to capture the added losses that cost segregation and bonus depreciation would provide us now and use them in future years when I move out of full time W2 and into REPS to then count against my wife's W2 income (we file jointly). 

We are in the contract under our respective entities names at this point but are contemplating whether or not it's beneficial/safe or whether it even matters whether we keep it that way or form a joint entity (LLC) once the loan is in place.
