I will have 2 checking accounts. One will be for myself, and the second will be for the realty company. By having separate accounts, it will be easier for a tax preparer, or accountant to manage any would be accounting issues that would arise. My checking accounts can not go above $250,000 due to FDIC insurance limits. If need be, I will move money to my Swiss account, and use a spreadsheet to account for everything. All of my personal income will go to my personal checking account. This will include my investment fund, and the salary I will give myself for the realty company. The realty company will have a checking account as well. I will look for the best bank for small businesses, and will use that bank, even if I will have to travel a little bit to interact with a teller, or branch representative. I would imagine this would not be a common occurrence as I will encourage my tenants to use the Rent Payment Service.
