Fix the property. Rent it or sell it. But there’s another side of real estate that can create cash flow, flexibility, and opportunity without only focusing on owning more property. At this month’s Columbus Investors Club, Tiffany and Josh High are sitting down with Eddie Speed - a real estate veteran with 40 years of experience who has closed more than 50,000 note deals. He has spent decades helping investors understand how to structure deals through seller finance and notes, and how to think more like the bank instead of just the buyer. This will be a practical conversation around a part of real estate most people have heard about, but very few truly understand. If you’ve ever wanted to know how to create more opportunities in deals, generate cash flow in a different way, or understand how seller finance actually works in the real world, this is a night you want to be in the room for. You’ll walk away thinking about deals differently, seeing new possibilities, and understanding how creative structuring can open doors that traditional investing alone can’t. **What You’ll Learn** * How seller finance works in real estate deals * How notes fit into real estate and create opportunity * How to structure deals more creatively * How investors generate cash flow by focusing on the payment * How to think like the bank instead of only focusing on owning the property * How this strategy can create flexibility in today’s market **Open Q&A - Ask Eddie Anything About** * Seller finance and how to use it in real deals * How notes work in a practical, beginner-friendly way * Creating cash flow without only relying on rentals * Structuring deals that others might miss * How experienced investors think differently about financing * Common mistakes investors make when they only focus on the property **Why You Should Be in the Room** Because the investors who win in the long run know how to do more than just buy houses. They know how to structure.They know how to create terms.They know how to see opportunities other people miss. This is the kind of conversation that can expand the way you think about real estate entirely. Come ready to learn, ask questions, take notes, and connect with people who are serious about growing in this business. **Reserve your free seat now - and be part of the conversation.** Grab your spot here ➡️ https://www.eventbrite.com/e/how-to-structure-real-estate-deals-using-seller-finance-and-notes-tickets-1984826171509?aff=cicmeetupapp

This is a free, in person meeting. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.
