New Landlord/Investor from Chattanooga, TN

Hello! My husband and I are buying the duplex we live in. There is currently another tenant, so we are just beginning our real estate investment journey and becoming brand-new landlords! I'm going to focus mostly on the landlord side and financials, and my husband is going to be the handyman/maintenance guy and will be completely remodeling the basement on our half of the duplex. This opportunity kind of sprang up on us, but now we're really excited about the opportunity and want to buy more multi-family homes in the future to bring in monthly income and build up money for retirement. Right now I'm doing as much research as possible in my spare time. I currently work full time but have a desire to make landlording my part-time job (and eventually full-time).
