I'm not a tax lien expert, but your order of seniority (RE taxes trump mortgage) seems correct.

For instance, Clintons and Trumps probably do not file all their assets on their personal tax return.

Remember all the "experts" predicted disaster if Trump won the last election.

This was started by Trump's tariffs, and this will turn into a flood.

Even though the cost delta between electric and oil is far less today, perception trumps reality for 95% of people; so just the words "electric heat" may affect the marketability of your units.

If Trump is reelected, those relationships will only be further strained.

Hi Miguel,Dave Lindahl has some good books, he has thousands of units, and knows his stuff.He wrote the book: Trump University Commercial Real Estate 101 : How Small Investors Can Get Started and Make It Big, (with a forward from Donald Trump) which might be of interest to you.Political factors in the East shut down Trump University, but some of the books are still available online.Good Luck!

@Justin Mathews, Tax free trumps borrowed money every time.   

The lesson I’ve had through observing the Trump administration is: They tell you in advance what they are going to do and they more often than not follow through.”ah.... there's truth in that.
