Mixing personal & rental funds (sole prop)

[Andrew S.]

Hey everyone, I have separate bank accounts for my rental business. The properties are owned in my personal name. Since I don't have an LLC, is there any concern/ caution/ potential future issue if I transfer funds to my personal brokerage account? My cash reserves has excess that I'd like to invest.

To protect myself, I have an umbrella policy versus the LLC. I do a lot of the work myself, so I don't feel I can argue that it's "separate from me".

Thanks in advance!
