I'm putting in an offer for my first ever Duplex this month and I have been fully catching up on laws, fees, security deposits, etc but I can't seem to come around the correct article to help me make the correct choice in choosing between a personal checking account or a business one. And also how to benefit the best with collecting rent. So the duplex is both 3bed 1bath, one side is rented currently with the other vacant which I will move into, I will also have 2 roommates on my side to gain more income. I do not know where to keep the income I make from my roommates and tenants... I want to grow my portfolio and eventually get into apartment buildings and create a large portfolio so I want to start all of the baby steps now for that path. I do not want to keep the income I make in my own personal account I know that for sure but I also would like to put my own personal money into that rental account so that I can have more money to put towards future renovations and also a security blanket, is that even possible for me to do? And last for the security deposit account would I just create another chacking account and keep all of the deposits in there and not touch it at all? Or would I need to create a new account for every new property I own? I do plan on creating an LLC but personally would like to wait until I'm getting closer on getting a second property before creating one is that also a good idea or would it be better to create an LLC now for this property and future ones?
