When I did her recent tax return she had $45,000 in passive losses from the rentals and $35,000 in income from her S-Corporation. I called her and found out how many hours she had only worked for three months in her S-Corp, which was less than 500/750 hours per year.  I changed the nature of the income from the S-Corporation to passive, thereby eating up the passive losses from the rental. 
There are basically three types of income: earned, portfolio, and passive. When it comes to filing your tax return, each of these types of income are taxed differently. Therefore, it is worth understanding the difference between the three to minimize your tax burden. Below are the three types of income, how they are categorized, and the tax implications for each.

My returns are based on full cash purchase of the properties, as it is hard to compare the attractiveness of properties at different price ranges when only calculating down payment or properties that need very little rehab/updates. I did think about the scores assigned to each factor, but I believe tax deductions are a SIGNIFICANT factor when comparing passive income steams.

According to Uncle Sam, you need to be "materially involved" in an enterprise to earn active income. With passive income, it's just the opposite, as the IRS deems you to be earning passive income if you're not materially involved with a profit-making enterprise. By and large, expect income to be taxable if you are engaged in a passive income enterprise. You will need to report earnings to the IRS.

If you do not meet any of the above criteria and you lose money on a real estate investment, you still may be able to reduce your taxes. First, use a loss on one real estate investment to offset a profit on another investment. If you make $20,000 on one apartment building but lose $3,000 on a duplex, you will end up with only $17,000 in taxable income from real estate activities. If you only own one property, the IRS usually allows you to carry that loss forward to offset profits in the future.
From what he describes, creating passive income definitely does not sound easy. It requires a serious ramp-up -- often requires 80- to 100-hour workweeks in the beginning, says Flynn. But once up and running, and depending on the content, some sites take fairly minimal maintenance. Green Exam Academy, the LEED exam study site he launched in 2008, takes just him four to five hours a month to maintain but brings in $250,000 annually.
My esteemed marketing colleagues initially balked at the idea of creating products that generate royalties, so I can understand how creating something from nothing might be daunting for those who aren’t even in creative roles. However, realize there is this enormous world out there of photographers, bloggers, artists, and podcasters who are making a passive income thanks to the Internet.
I’m not sure they’re screwed. They’re playing by the same rules as the rest of us. We can all become a capitalist just like you and I are doing. In fact, that’s really the goal for most of us- get to a position where our capital can support us. If they have a particularly low income, they’re not paying income taxes anyway (see famous 47% comment which as near as I can tell was true of federal income taxes and will continue to be true, although perhaps with a slightly different number, under the proposed House plan.)
Making legitimate passive income isn’t as difficult as you might think. Some of the best passive income ideas might take a little time to set up but can start cash flowing within a couple of months and will provide a consistent monthly income for years or more. The most important point is just to get started. You make exactly $0 on the passive income sources you never start.
Speaking from our own experience, you can’t be a passive McDonald’s franchisee. Every McDonald’s potential franchisee will need to complete at least thousands of hours of training before he/she would be approved to acquire a franchise and only if he/she has the financial resources to acquire a franchise. It could take years before one would get a single store franchise. Until the franchisee eventually has acquired multiple stores and established his/her own management team, the franchisee would have to put his/her nose to the grindstone and work his/her ass off every day. I won’t call it a passive investment by any stretch of imagination.
Despite the anger expressed by the tax community and business owners across the country, the government reiterated in October 2017 its intention to move forward with the proposed passive income rules and promised that further details will be revealed as part of the 2018 budget. February 27, 2018 was the date that the so anticipated federal budget was released and to the surprise of tax practitioners and private business owners, the government completely abandoned its July 2017 passive income proposals. The 2018 budget instead proposes to further restrict the access to the small business deduction (which will not be discussed here) and to refine the refundable taxes regime applying to CCPCs. The proposed new refundable taxes regime is less complex and less costly than the framework suggested by the July 2017 proposals, however, Finance proposes to limit another type of tax deferral allowed prior to the budget as discussed in more details below.
In most cases, all rental real estate activities (except those of certain real estate professionals, discussed later) are passive activities. For this purpose, a rental activity is an activity from which you receive income mainly for the use of tangible property, rather than for services. For a discussion of activities that aren’t considered rental activities, see Rental Activities in Pub. 925.
Investing in rental properties: Another form of real estate investment, rental investments (i.e. becoming a landlord) could steer you down the passive income path of steady monthly rent checks that you can use to pay off a mortgage loan on the rental property. After the mortgage is paid off, those monthly checks go right into your bank account -- potentially for years to come. 
Fulfillment by Amazon (FBA) is another model that has been gaining popularity in recent months. The major difference from the model that I described above is that instead of shipping it to a warehouse, you ship it directly to Amazon. For a cut of the money on each sale (and they also charge storage costs), they package it all up and send out your order. You make less money than doing it yourself, however once set up, it does have the hands-off factor going for it.
The rules in the next two paragraphs apply to any financing incurred after August 3, 1998. You also can choose to apply these rules to financing you obtained before August 4, 1998. If you do that, you must reduce the amounts at risk as a result of applying these rules to years ending before August 4, 1998, to the extent they increase the losses allowed for those years.
Passive income investments can make an investor's life easier in many ways, particularly when a hands-off approach is preferred. The four options outlined here represent differing levels of diversification and risk. As with any investment, it's important to weigh the anticipated returns associated with a passive income opportunity against the potential for loss.
My goal is to generate enough passive income (ultimately; for the next few years, I’m definitely working for it both with a day job and property managing my investments) to do what I want, when I want, how I want, and where I want. We all define that “what, when, how, and where” differently, and to each of us, financial freedom means something different.
One of his favorite tools is Personal Capital, which enables him to manage his finances in just 15-minutes each month. If you sign up and link up an investment account with $1,000+ within 40 days, you get a $20 Amazon gift card. They also offer financial planning, such as a Retirement Planning Tool that can tell you if you're on track to retire when you want. It's free.

If you can save a lot early on in life, you can build up sources of unearned income, and this income will be exempt from payroll taxes. This is good news for investors and for retirees. Any pre-tax salary deferral contribution made to a retirement account, pension plan, or other pre-tax contribution will lower the amount of federal and state income tax liabilities, however, they do not lower your payroll/FICA tax - the FICA tax has already been taken out of gross wages. 
I have to agree. Our Duplex cost us 200k initially in 1998. Over time and completely refurbishing the property with historically appropriate sensitivity, we invested another 200k or so. We just had a realtor advise us we could ask 700k for it today. It nets us 30k annually after taxes, insurance and maintenance. We still have a loan on it which I have not taken into account, that will be paid off within 5 years if we keep it. My mental drama now is, while I am quite giddy over the prospect of earning a tidy sum of profit if I sell, what then would I do to equal the ROI and monthly income this thing generates? Rents are low, they should be 4k a month and will only go up. Tempted to keep it and not sell. And while I do have some stocks, I basically suck at them. I am much better at doing properties.

Vanguard: Vanguard has a minimum of $50,000 and a fee of 0.3%. Rebalancing is done automatically once every quarter and tax loss harvesting is done on a client-by-client basis. We included Vanguard because clients who invest between $50,000-$500,000 have access to a team of financial advisors. Those with accounts over $500,000 will have a dedicated advisor.
