Here are some tips to help you survive a bar crawl: Read The Communication Beforehand: we will send out information to you via email before the Crawl to know where and when to go to check in and register. Arrive On Time: If you arrive late to registration you might miss out on some of the fun. Pace Yourself: It's essential to pace yourself and drink responsibly during a bar crawl. Stay Hydrated: Drinking plenty of water can help you stay hydrated and reduce the risk of a hangover the next day and help with your overconsumption of alcohol during the Crawl. Eat Beforehand: Eating a substantial meal before the bar crawl can help absorb alcohol and prevent you from getting too drunk too quickly. Dress Comfortably: Wear comfortable shoes and clothing that allows you to move freely and stay cool. Stay Safe: Stick together with your group, and make sure to have a designated driver or plan for transportation at the end of the night. Conclusion In summary, a bar crawl is an event where a group of people visit multiple bars or pubs in a single night. And it can be a great time as you travel from bar to bar.

Columbus in-person chapter meeting: Your 2026 Buy Box + Successful Rentals 101
(Note: RSVPing here on meetup does NOT reserve your seat. To do that, you’ll need to register at our website, **[HERE](https://www.coreerocks.com/Events.aspx?ID=Columbus-in-person-chapter-meeting-Your-2026-Buy-Box-Successful-Rentals-101-14-3-3-2026)**.)
Let’s be honest. In 2026, you can’t use 2023 strategies and “hope” a deal works out.
Demand for rentals, wholesale deals, retail deals, and even loans has changed, and that means that the most active, experienced investors have changed the way they do deals (and maybe even the kinds of deals they’ll do).
Here at COREE, our job is to shortcut your learning curve by introducing you to the people and concepts you need to take the shortest path from here to financial freedom, and we think you’ll agree that this meeting is a no-brainer, if you’re serious about making wealth-building deals this year.
Here’s the detailed agenda:
From 6:00–7:00 p.m.,
From 7:30–9:00 p.m.,
Agenda:
5:00–6:00 p.m. Complimentary Light Dinner & Networking
6:00–7:00 p.m\*\*. New Investor Meeting: Basics of Making Money in Rentals with Vena Jones-Cox\*\*. If you’re planning to buy rentals today, you have to know how to evaluate the REAL income and expenses before you make an offer. If you’re new, you’ll finally understand how rentals really produce profit. If you’ve been around a while, you’ll see how today’s numbers change the math.
7:00 –7:30 **Buy-Sell-Trade (Members Only)**
Bring your deals, money, buyer lists, referrals, and requests.
Fast-moving. Bring flyers or business cards.
Guests get a quick orientation with Executive Director Vena Jones-Cox.
7:30–9:00 p.m. **Main Meeting: Your 2026 Buy Box: What Experienced Investors are Buying in 2026 (and what they won’t touch).** Our panel of active, experienced investors will lay out their 2026 buy boxes. Not hypotheticals. Not “in theory.”
What they are actually buying—and what they won’t touch.
They’ll share:
* What property types investors are actively pursuing
* What strategies they’ve stopped using
* The exact numbers they require before they say yes
* How insurance, taxes, and rates have tightened the buy box
* What instantly disqualifies a deal in today’s market
* How to define your own 2026 buy box based on capital and risk tolerance
Members and non-members at any level of knowledge and experience are welcome—as long as you’re serious about real estate, value experience-based, no B.S. education, and want to give as much as you get.
Remember, to actually reserve your seat, you have to go **[HERE](https://www.coreerocks.com/Events.aspx?ID=Columbus-in-person-chapter-meeting-Your-2026-Buy-Box-Successful-Rentals-101-14-3-3-2026)** and register on our website!
