We have never used Banaque de MTL.  

I am looking for a CPA in the Delaware County, PA area that has experience with real estate investors who own single family rentals.

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. 

This is the world of Delaware Statutory Trusts.

I was optimistic on the project until I read this:https://www.expressnews.com/real-estate/article/De...Does anyone know if he has ever actually finished a development?

Bennett, have you looked into Delaware County?

:https://www.immobilienscout24.de/expose/119411702#/Current owners are getting ~14.6 EUR/m2/m and selling for about 5K/m2. 

My only debt is my 4 bed 3 bath home in Dover Delaware where I live that I'm currently renovating and will cashflow ~$300 when finished. 

I concur with @Ned Carey that wholesaling by an agent, at least using the method of an assignable contract is a de facto net listing.
