.: I set up LLC's on the secretary of state website for $50 and it takes about 10 minutes. 

I recently signed up for BP and found the calculators on this site to be very helpful.  

For example, to get up-to-date property tax data you would need to scrape every county's tax data website (thousands of different websites, data formats, issues, etc...) then aggregate and clean the data.

At my age, I wonder if it’s too late to "get rich slow," as is the case with most real estate investing.I’m curious: is there a section of this website or a community that focuses on late-start investors?

This website is a nice starting point as you are deciding on what location to choose from.

TIAMichigan is fairly easy on Michigan Lara website it’s $50 to open a new LLC and they’re fairly quick with their turnaround.

There are a lot of websites that offer the course online, or if you have a college near you, they also typically offer a class that satisfies the pre-licensing requirement.

I would also look at the availability of public water and public sewer, if not at the site how far away are those services.

What specific websites will they advertise your vacant property on?

But consumers all are on the site for free where real estate agents are constantly hawked to buy leads or participate in what is now a 35-40% referral business for unvetted leads who think they are contacting the listing agent.Their business model has always been flawed.
