I've seen a situation two years ago where a new landlord had trouble evicting a tenant who was constantly late on payments because the tenant argued that the late payment terms in the lease had not been honored since the start of the lease and couldnt be suddenly enforced because of this. 

Who is in trouble if the payments are not made?

There definitely is better but I wouldn’t say one is bad." ....This is a misconception that gets many in trouble. 

Gifting equity in a house may be more trouble than it is worth if you are not near the life-time exclusion1) Potentially having to get the property appraised everytime an equity is gifted2) Having a title company update the title every time3) Exemption of the gift tax return is normally for cash gifts below the annual gift tax exclusion, you may still need to file if you gift non-cash4) If there is partial ownership over several years, having to properly pro-rate certain items such as real estate taxes, mortgage interest and rental income if the property is a rentalBest of luck 

You're financed at 100% and would be in big trouble if (when) ANYTHING went wrong....would the property even cash flow enough to service all of that debt? 

Do you have first-hand knowledge or experience with these businesses, or are you just looking to stir up trouble? 

I would get into trouble?

The rule of 5's, or 5% for capex, maintenance and vacancies is going to get you in trouble.

As a heads up they have a reputation as being difficult to work with--especially with regard to trouble college kids might get into (bonfires, parties, trash etc.).
