For those of you who don’t want to come up with a $220,000 downpayment and a $900,000 mortgage to buy the median home in SF or NYC, who don’t want to deal with tenants or remodeling, and who wants to not do any work after the investment is made, check out Fundrise. They are my favorite real estate crowdsourcing company founded in 2012 and based in Washington DC. They are pioneers in the eREIT product offering and they’re raising an Opportunity Fund to take advantage of new tax favorable laws.
You can offset deductions from passive activities of a PTP only against income or gain from passive activities of the same PTP. Likewise, you can offset credits from passive activities of a PTP only against the tax on the net passive income from the same PTP. This separate treatment rule also applies to a regulated investment company holding an interest in a PTP for the items attributable to that interest.
The average period of customer use of the property is 7 days or less. You figure the average period of customer use by dividing the total number of days in all rental periods by the number of rentals during the tax year. If the activity involves renting more than one class of property, multiply the average period of customer use of each class by a fraction. The numerator of the fraction is the gross rental income from that class of property and the denominator is the activity's total gross rental income. The activity's average period of customer use will equal the sum of the amounts for each class.
Qualified dividends are taxed the same as long-term capital gains. In 2018, you can earn up to $38,600 in ordinary income without being taxed on long-term capital gains or qualified dividends. If you earn between $38,600 and $425,800 in ordinary income, your long-term capital gains tax rate is 15 percent, which would also apply to qualified dividends. If you make more than $425,800, the rate is 20 percent.
Passive income is definitely the goal and I think you hit it on the head with the point about upfront work. That actually coincides well with most physician careers. Work hard like a resident and spend like a resident to build up an investment portfolio right away while you are young and full of piss and vinegar. It then has time to grow and be there for you as you need or want to slow down because of aging or kids etc. Plant the seeds early and then live off the crops.
