1. All real estate is local. The US is FAR from a homogeneous market. Most real estate investors buying single-family homes are NOT buying $1 mil houses in coastal states. They are buying 5- and low 6-figure houses in suburbs of growing or stable inland cities.
2. Analyzing real estate investments is not at all like analyzing a purely financial instrument like a bond. Practically none of the numbers are set in stone and every single deal is different from the next in every way you can imagine. It takes a lot of education, practice, and some experience to get good enough at this to not lose your shirt.
3. All successful real estate investors are also good at networking. They go to meetups, they have mentors, they hang out with each other and share information. They form amicable business relationships with real estate agents, contractors, and property managers.
4. There are many kinds of real estate investors, each with their own set of goals, skills, and strategies. It is virtually impossible to just copy whatever someone else is doing and do it well because you are not them. Some investors are at it full-time and end up being multi-millionaires. Some investors want extra income to supplement their full-time job or pay for their kids' college tuition. Some are retired and want a way to grow their nest egg. Some just want the park their cash in an appreciating asset for a few years. Some are good at finding properties well below market rates, some are good at negotiating, some are good at renovating homes at low cost, some are good at being landlords. ALL are good at analyzing deals. You have to figure out what you are good at and whether those things can help make you successful.
If this is something that truly interests you, I would suggest reading a few introductory real estate investment books from well-regarded authors and hanging out on the Bigger Pockets forums. There is a staggering amount to learn and it's not for everyone.
