Almost seems too good to be true to me.3. 

It is true that before the purchase we needed to do quite a lot of work to make sure everything was organized with the payments of the debt etc.

That is very true, I understand where you are coming from.

But I did the math and for me personally that was true, I'd pay off my mortgage 5 years early if I paid an additional $100 each month to principle. 

It's not entirely true, but the point is that you need to figure out what motivates you to get going every day.

I'd like some true feedback from current users as there's not a lot of review to be found online.

These are true STR expenses listed, not the typical “oh, you just have to pay for your mortgage and utilities” logic some “gurus” teach.

Sad, but true.

Is this true?

However, if this is a true "joint venture", all members must be actively involved in generating their own profits so the credit partner would also need to participate in decisions regarding the property such as which contractors to hire; handling issues that arise, etc.
