However, you should pick a niche and blog about that. If you're launching a money related blog, maybe it'll be about how to make money in real estate or simply how to make money online. Pick the niche and stick to it. If it's a diet and fitness related blog, maybe the niche is the Ketogenic diet, the Atkins diet or some other form of diet or fitness.
Add Leverage (Mortgage) and you greatly increase the ROI especially from the perspective of using Rents (other peoples money) to pay down the mortgage and increase your equity in the property over time. At this point then yes price appreciation is secondary bonus and we have an arguement of how and why Real Estate can be better than Growth Stocks in some scenarios and for some investors.
If your modified adjusted gross income (MAGI) is $100,000 or less ($50,000 or less if married filing separately), you can deduct your loss up to the amount specified above. If your MAGI is more than $100,000 (more than $50,000 if married filing separately), your special allowance is limited to 50% of the difference between $150,000 ($75,000 if married filing separately) and your MAGI.
One of the latest trends is crowdfunding / syndications where money is pooled together to directly invest in various real estate properties.  You do not get quite the variety and diversification you would in a REIT but it provides an opportunity to invest a smaller amount of money than purchasing a property directly.  Usually, you are a limited partner in a partnership.  Since you are not materially involved in the day to day activities, the income generated is passive income.

Let’s say a company earns $1 a share and pays out 75 cents in the form of a dividend. That’s a 75% dividend payout ratio. Let’s say the next year the company earns $2 a share and pays out $1 in the form of dividends. Although the dividend payout ratio declines to 50%, due the company wanting to spend more CAPEX on expansion, at least the absolute dividend amount increases.

I wanted these freedoms so I began pursuing a means to have those, which in my case ended up being starting my own company that I could work from anywhere and with no deadlines whatsoever (although the no deadline thing does make things hard sometimes). The income from that company is planned to continue buying more passive income investments so eventually I hit total financial freedom where I can keep living my current lifestyle minus the work part. All of this is called “lifestyle design.”

Blogging is still going to take work starting out. That path to $5,000 a month didn’t happen overnight but just like real estate development, it build up an asset that now creates constant cash flow whether I work or not. I get over 30,000 visitors a month from Google search rankings, rankings that will continue to send traffic even if I take a little time off.
Squidoo (which later became HubPages) is how I got my start with making money online and over the years, I’ve probably earned $5000+. It’s great for those who don’t want to bother figuring out the self-hosted website thing. HubPages’ drag and drop platform is ridiculously easy to use. What isn’t easy, however, is getting past their spam filters. My most certainly not-spammy Hubs have gotten un-featured and it seems that there’s nothing I can really do about it. I’ve given up on HubPages, but perhaps you’ll figure out the secret recipe and have more success than I?
I have only dabbled in drop-shipping before when I had an eCommerce platform 6 years ago or so. I think it is something that you could do on the side, but you would want to do in depth research on the industry you want to get into before setting up shop. It may be a little less passive up front, but over time you could take your hands off the wheel.
