From 1 to 4 Doors- banking questions

[Cole Nardi]

I have 1 condo that has been rented for 5+ years. I am now scaling up and moving out of my SFH (will rent this) into a house hacked duplex by the end of the month. I had a few questions now that I am starting to scale. I own all these properties in my name and do not have an LLC at this point.

1) can I use my business checking for all of my rentals, or would you recommend separate checking accounts for all 3 doors?

2) how do I manage the expenses for moving in and mortgage payments on the house hacked duplex? Does any one have a good site detailing preferred methods for paying mortgage/expenses when you are part owner occupant?

Thanks!
