1) If your property is not under rent control, you have the ability to raise rent to market prices with proper warning. In SF, I have to give tenants a one month warning for up to a 10% increase and a two month warning for up to 60%. Rent control limits to an inflation index, usually around 2% a year, which is why initial pricing and tenant turnover is important for better profitability.

I truly believe generating $10,000 a year online can be done by anybody who is willing to dedicate at least two years to their online endeavors. Here is a snapshot of what a real blogger makes through his website and because of his website. Roughly $150,000 a year is semi-passive income followed by another $186,000 a year in active income found through his site. Check out my guide on how to start your own blog here.
One aspect you might want to add to your scoring is “inflation protection”. At one end, bonds and CDs generally pay a fixed nominal coupon that doesn’t rise with inflation. Stock dividends and Real estate rents (and underlying property value) tend to. Not reallly sure how P2P lending ranks- though I suppose the timeframes are fairly short (1 year or less?) and therefore the interest you receive takes into account the current risk free rate + a premium for your risk. Now that I think about it, P2P lending probably deserves a lower score in the activity column than bonds too (since you probably need to make new loans more often).
Freelance writer: If you have a knack for writing, you can earn great money writing for others. Not sure how to start? Contact bloggers, who are always looking for great writing. As blogs grow, they can afford to pay freelancers good money for quality articles. Websites looking to build links also hire freelancers to write guest posts to be published on blogs and websites.
The one thing I learned though from all those childhood experiences though is that you never can depend on one source of income. Eventually my mom caught on and stopped giving me all those extra bags of chips and I had to figure out a new way to make money. No matter how safe something seems there’s always the chance that you could lose that income and be stuck with nothing.

I like the way you have listed the ways to earn extra income and was quite surprise that you did not make mention of network marketing, which is a way to make extra income without quitting your regular, though most people view mlm as a pyramid scheme but the real pyramid scheme is a regular 9 to 5, because you can only have one president of a company at any given time and network marketing business model to promote product that can be used is really cheap to join and can offer a substantial extra income or what do you think?
I have had a LC account for almost 2 years. Invested 5k. A lot of very small loans. Unfortunately I had to invest though Folio FN. The fees reduce your return. Now, they are not even allowing that. My interest and return of principal are not being reinvested. I talked with LC and they are working on it for my state. Even if I can obtain access to the prime portfolio, I would only place 10 percent of my cash here and would reinvest for at least 3 years. I am still concerned about what would happen when a recession hits.
I had to get out. I actually had this random Facebook ad come up in my news feed (go figure) and it eventually led me to a webinar that taught on how to start an email marketing business (which is, by the way, the most profitable form of affiliate marketing – or ANY marketing for that matter). I listened through the whole 2 hours, completely mesmerized. By the end of it, I knew what I was going to be focusing on to help my family out of the pit of debt we were in and into a world free of financial stress. I didn’t know if it would actually work, but eventually it lead to EXCESS income!
That $200,000 a year might sound like a lot to you, but the median home price in San Francisco is roughly $1.6 million or almost eight times our annual passive income. For a family of three in 2018, the Department of Housing and Urban Development declared that income of $105,700 or below was "low income." Therefore, I consider us firmly in the middle class.
Another way to generate passive income is to invest and be a silent partner in a business. This is very risky, but with risk comes the potential for high returns. For example, several years ago both Lyft and Uber were looking for private investors to invest in their companies. Today, they are worth billions - but you as an investor would only reap that benefit if they go public via an IPO, or get acquired. So, it's risky.
Let us start by creating a corpus to invest your money. Let us say you are 25 years of age and earning Rs.75,000 per month after completing your MBA. You can save Rs.10,000 per month in an equity fund as you have other commitments with the rest of the money. But starting off with Rs.10,000 per month in an equity fund SIP is not bad enough. Here is why.
Who cares, especially when very conservatively, the ultimate passive income includes a six digit or more base lease, plus an estimated additional six digits or more for rate increases and another six digits for more for various smaller and one bigger technology increase at 25 years. All four (base, rate, smaller and mega technology increases) combined, certainly could yield much more depending upon inflation, rate increases and technology increases?
Which all goes back to my point – since companies change in a lot of unpredictable ways, it makes more sense for passive income to just ride the market by investing in a Total Domestic Stock Market, Total Bond Market, and Total International index funds, with allocations that depend on your goals and time horizon. For income, withdraw 4% or less, depending on what research you believe, and you’ve got a pretty low risk strategy.
The reverse can also be expected unless the rents rise too.  This rental increase might occur if we imagine interest rates are rising because the economic environment is improving.  At present, it is widely expected that rates will rise ever so slowly over many years.  Indeed the US has been looking for the courage to do this over recent months and they may start rising there soon.
