I earned it by having to endure tenants sit outside, drink lemonade, and watch me paint the outside of their house. 

I bought the biggest house I could afford because that was the conventional wisdom then, not realizing there were other alternatives that would have let me achieve financial independence much sooner than I did ("live and learn").I never ran a business as a kid (lemonade stand, deliver newspapers, whatever).

In fact, I know they will be thrilled and perhaps bring me a glass of cold lemonade. 

Buying stocks on dips a bit, consulting for free on BP (and the advice is worth what you pay for it), considering a crypto dab below $7k, maybe notes, maybe another nap or a franchise of lemonade stands now that it's getting hotter.Seriously, stick with good real estate.

So if this year you sell lemonade and put it on Schedule C as "lemonade sales," and then next year you sell lemonade and put it in a "lemonade sales" S Corp, some investors (particularly jumbo) will view that as 1 year Schedule C, 1 year S Corp, no two year history of receipt on tax returns, loan denied.In general, for self employed folks that want to qualify for a mortgage within the next few years, pick how you're going to report that income to the IRS, and stick to it.

If aren't going to operate with integrity and deliver something of value, then heck, doesn't even matter what the activity is - running a lemonade stand would get a bad name.

@Bill Brandt congrats on making lemonade from lemons.

Winter Strawberry Capital of the World! 

We have learned to turn lemonades into lemonade.

I don't care if you're operating a lemonade stand on your street corner every other Sunday, a business is a business.
