Obviously, you want the best tenants you can find. If you’ve chosen a property in a more affluent and stable neighborhood, your tenants are more likely to be responsible with your property and reliable about paying the rent. Properties in lower income areas are more likely to attract tenants that become delinquent in paying the rent, move out without notifying you, and damage your property. This is part of the higher risk of this type of investment property. You’ll end up with the expense of repairs and less income to spend on those expenses.

Of course, there’s nothing to say you can’t do both. You can manage your own commercial real estate rentals and flip houses while you have someone else help manage residential rentals. You can invest in REITs and real estate crowdfunding. You’ll get the higher returns of active management while benefiting from the diversification and ease of passive income through other sources.
As I mentioned in a previous post on the 3 Types of Affiliate Marketing Explained, the way I earn money with affiliate links in ALL of my online businesses is by promoting only products that I have used, and only what I would recommend to my friends who want to achieve similar results. I feel that anyone with an audience has a responsibility to do the same thing.

Repackage your products. If you've already created successful content on a blog or website, you can convert that information into another form and sell it. For example, you can compile what you've written into an ebook and sell it on one of the ebook markets like Amazon or Barnes and Nobles. Alternately, you can use it to create an online course to sell on a website like Udemy. Reworking your content can earn you additional income streams without requiring you to actually produce new content.[13]
Good suggestions. I have many of these. One word about the “app” idea. I had a great idea related to personal taxes that I tried to get off the ground with my accountant as a partner. I would say it’s difficult to do this unless you have a coder on your team. Hiring someone is not really viable financially unless the app is simple. When we finally got the quote for a coder to write what we wanted (and after doing lots of mock ups ourselves and getting a demo for investors) the estimate was about 750k just to really get started.
A REIT is a company that owns, operates or finances real estate and allows anyone to invest in portfolios of real estate assets, the same way as stocks: you can purchase individual stock or exchange-traded fund (ETF). You can then earn a share of the income produced through the real estate investment without having to own, manage or finance a property.
* I use Personal Capital to track all my finances in one place. It’s much easier to use their free software to follow 28 accounts on one platform than to log into various accounts to check my balances. They’ve also got great tools for x-raying your portfolio for excessive fees, recommending a more optimized asset allocation, and planning for retirement with their Retirement Planner.
