About the product
AAC20 controller (iSMA-B-AAC20) with inbuilt display is an advanced device to control building automation and HVAC systems. Use of SVM (Sedona Virtual Machine) allows you to finish the setup quickly and easily. It is ideal for smaller projects where you want to stay open protocol while keeping the development simple and the cost under budget.
With the large number of inputs and outputs allows to integrate with other devices and sensors (AAC20 provides 8xUI, 4xDI, 4/6xAO and 4xDO). Its fast processor allows to control of even very large objects. Built-in RS485 can be used to expand number of I/O by connecting MINI or MIX series I/O modules using Modbus ASCII/RTU. In addition, to increase the versatility of the controller, it supports many open communications protocols like: BACnet, Modbus, SOX, DALI, M-Bus, 1-wire or oBIX (optional). AAC20 is mounted in a housing adapted for DIN rail mounting or directly on a panel. Separate, easy to remove connectors allow quick wiring without removing the entire module.

This 2-in-1 boxset is an absolute must-have for anyone looking to break into real estate investing, regardless of experience or financial situation. The first book is a step-by-step guide that breaks down the intimidating world of real estate into 7 simple steps, perfect for beginners.

I especially appreciated the practical advice on how to finance your first deal even if you're starting with little money or poor credit.
The second book dives deep into rental property investing, offering a wealth of knowledge on both long-term and short-term rental strategies. Whether you're aiming for mid-term rentals or vacation properties, this guide equips you with the tools to confidently manage your investments. The inclusion of expert tips on property management, deal analysis, and exit strategies is invaluable for anyone looking to scale their real estate portfolio.
The extra bonuses, including guides on tax planning, apartment investing, and property checklists, are just the cherry on top.

Extremely thorough yet easily readable...
Format: Kindle
Describing this book as thorough is an understatement. The title starts off with a bold claim, one that might seem skeptical, but the authors actually delivered. I'm beyond impressed, to say the least.
I've had my nose in this book off and on all day and yet I'm still only exactly 33% through it. I'm not even sure I can say I'm reading this book. It's more like I'm studying it.
Chapter 6 in particular rang a bell. "Buy on the fringe and wait. Buy land near a growing city!" This reminds me of an approach I know and love which is self-titled "the borderlands strategy." Hello places like Frisco, TX / Dallas suburbs.
This book is a masterclass in professional, knowledgeable people offering an extremely high-quality product at a great price. There are even enticing offers at the end of each chapter, which is something marketers (and real estate individuals) can really take note of. (Lead gen.)
So many good things to say. Probably the most concise way of doing so is by saying it really is a real estate bible, yet is still easy to read. No complex terms or challenging math. No walls of text. (Examples that do include math are straightforward and easy to follow.)
Great buy that has been extremely enjoyable and thought provoking. Can see myself referring back to this constantly for years and years.

Solid breakdown of real estate investing for beginners
Format: Kindle
Aye, this book actually surprised me. It’s super beginner-friendly and doesn’t just throw a bunch of complicated real estate jargon at you. I think in Chapter 5, they covered creative financing options, which I found pretty dope. There’s a part where they explain “subject-to financing” basically, how you can take over a mortgage without making a new one, which could mean little to no down payment. Didn’t even know that was a thing.
The book also lays out step-by-step strategies for getting started, from choosing a strategy to closing deals. Some parts felt a little surface-level, and I kinda wish they went deeper into financing for people with bad credit, but overall, it’s solid.
If you’re new to real estate and want a simple, no-BS breakdown, this one’s worth checking out.
