If you are not able to get a mortgage on the property, there are still a few options available though rates can be fairly high. You might try approaching the seller for owner financing where they sell the property to you on monthly installments. This might not be possible if there’s a mortgage on the property since many carry a “due on sale” clause. If you do go this route, make absolutely sure you get a notarized contract with all the details.
We usually think of Craigslist as a place to buy and trade random stuff, but Craigslist can actually be a great opportunity to sell your services online to an active and engaged audience. Simply check the “jobs” section and “gigs” section for specific cities and see if anything matches your skills. The great thing about Craigslist is that it is one of the highest converting traffic sources on the internet (think active buyers) which can mean more opportunities at higher pay.
I had the same experience when my name’s frequency on the call schedule dropped for reasons that no one would discuss and were not easily discerned except by those in the know (who were staying mum). I went and found another job…. and I wish that I had found something with passive income – it’s been several years now that I’ve been working 2-3 part time jobs and I’m trying to figure out what my other thing is going to be… still working on that, but I am thankful that there are others out there discussing side gigs and alternatives to medicine.
Even if you don’t have the skills right now, it’s possible to develop them. Envato Tuts+ has a load of great courses that teach you how to make WordPress themes, Photoshop actions and so on. If you invest a few months into learning the necessary skills, you might well be able to carve out a spot for yourself in the Envato Market or in our new curated website Envato Elements. 
One of the best ways to build wealth is to get a handle on your finances by signing up with Personal Capital. They are a free online platform which aggregates all your financial accounts on their Dashboard so you can see where you can optimize. Before Personal Capital, I had to log into eight different systems to track 28 different accounts (brokerage, multiple banks, 401K, etc) to track my finances. Now, I can just log into Personal Capital to see how my stock accounts are doing, how my net worth is progressing, and where my spending is going.
One of the most appealing options, particularly for millennials, would be #12 on your list (create a Blog/Youtube channel). The videos can be about anything that interests you, from your daily makeup routine (with affiliate links to the products you use), recipes (what you eat each day) or as you mention, instructional videos (again with affiliate links to the products you use). Once you gain a large following and viewership, you can earn via Adsense on YouTube.
Absolutely Federico. I still invest in real estate but no longer carry the misconceptions that it’s passive income. Fortunately, I’ve held my real estate properties long enough that they cash flow even after paying for management but it was a lot of work in the beginning. Real estate is a great investment but passive income investors should look to REITs and other investments rather than direct investment.
Another benefit, which many online entrepreneurs do not even consider, is that you don’t need to create the whole product before launching it. You only need to create a small portion of your actual content, and complete it only after you get your first member during his membership - that means you get paid IN ADVANCE of actually creating your site content. It also means that you can modify your content based on LIVE feedback from paying customers. More importantly, this is a great way to VALIDATE your site and ensure you create a product based on what customers want, not just what you think they want.

If you have specialized knowledge in a certain topic, you can put together an online course to teach others. For example, if you have experience in real estate investing, you can create an online course “Real Estate Investing 101”. The benefit of an online course is that once you create the course material, you can sell it to as many people as you want.
