I am Jerron and me and my wife just had twin boys. I've been trying to get in the rental business for a while and I think my wife might finally be onboard as kind of a college fund for the boys. I am looking at a duplex for around 130k rent is 1350$ per month. What are some key components to look into deciding whether 20% down would be worth the drain on my free capital. I may have a lender willing to go to 10 or 15%. What would be considered good to great cash flow on a property? Looking forward to getting more serious about rental investments and learning from all of you. Thanks and hope to hear from you soon.
