When people are too emotionally attached to their rentals they make all kinds of irrational choices and tend to overreact to tenant incidents which are simply a cost of doing business.  

It means herds are jumping in making irrational decisions in the markets.What goes up must come down especially sub-par assets.4 to 6 years ago you could buy great assets in SFR for cheap pricing in A to B areas.

Especially when the guest is acting particularly irrational. 

Market and his wild irrationality to your world.The skillset to successfully invest in equities is way more difficult in my opinion for that reason.I recommend reading Intelligent  Investor By Benjamin Graham, Snowball by Alice Schoder (Warren Buffett autobiography)  Poor Charlies Almanac to get a good start.CHECKOUT crowd funding alternatives:@Jilliene H. is way to modest to point out that her crowd funding portal is first rate and should offer the direct investment alternative that would eliminate public market volatility.

Am I being irrational to think that I can get into this with no money down?

I'm the first one who would like to see a correction, but sadly, I don't see it happening soon.The fact that it's been irrational for 10 years doesn't make it any more sustainable or any less likely to correct.

“The Market can stay irrational longer than you can stay solvent.”Sounds like to me everyone knows the market is acting irrational, but no one wants to get off the ride too soon.

Any sane guest can clearly see this is a totally irrational person.

You basically double your money every year and in the 10th Year, you would receive $1,024,000Obviously, if you calculated that $1k turning into $11k is a 100% per year return, THAT IS THE WRONG ANSWER.You need the IRR to calculate it for you correctly at 27.1%This is why EVERY REAL ESTATE INVESTOR NEEDS TO KNOW ABOUT CASH FLOW... and I will throw in the IRR at this point.Hopefully the readers of this post will understand that by understanding more sophisticated calculations, you can answer these seemingly easy problems.When I get someone, which is very often, that tells me WOW.. that's a 100% per year return!!!!

Saying, 'the rise in student debt is causing a bubble' is a meaningless statement, since if it doesn't trade it can't have it's price bid up to irrational levels.
