@Sonal Chopra first it would be a loss of a family member which is never a good thing to lose someone.For the sake of the exercise.

No lender will qualify your income earned from a short term rental based on a profit and loss.

I feel that the coinvest should be meaningful enough to cause real pain for the GP in the event of a bad outcome, but not so much pain that a bad outcome or 100% loss ruins them or threatens to disrupt their lifestyle either. 

Banks/Lenders use a theory that if an investor encounters a loss be it in income, death, divorce, major sickness, or any other set back they are more likely to let their 2nd lien positions go in default before a 1st lien.Reason why I say this is although you have a great rate on the first mortgage you need to let it go and do a "Cash out refinance".

Here is my situation:I've owned and lived in my house as my primary residence for 3 years.Up until the last year, I have rented out spare bedrooms (space within the living area).I got married about a year ago and my spouse has now been living in the house as her primary residence for 12 months.Question 1: IRS publication 523 states in the section under Business or Rental Use of Home, "If the space you used for business of rental purposes was within the living area of the home, then your usage doesn't affect your gain or loss calculations.

If you were to be sued and loss, where would they fall in terms of collecting money?

IMO it will be a loss.

Many companies will do notes or bonds that are unsecured debt against company as they don’t want to pin it to every asset which is not uncommon - but when they take on additional debt that is secured and/or start to incur massive losses that’s when it gets hairy.

Pick your poison carefully though or it can cause a loss on both sides.

If you've got losses or a favorable tax situation then take the commission by all means.
