(I honestly have no idea)

The exception is: When the 2 members are married spouses who reside in a community property state. 

@Nicholas A.House Hacking a primary residence is the best way to generate wealth. 

@Heather Bailey When house hacking with a separate rental unit, ensure proper insurance by obtaining landlord or short-term rental coverage tailored for Airbnb activities, in addition to your primary residence policy.

Also, did you have any other loans (ie student loans, primary residence mortgage, etc) when you took on the $25k? 

Quote from @Khon Kounbandith: Investment Info:Single-family residence fix & flip investment.

Just be sure to clarify that she isn’t a leaseholder but is authorized to reside in the unit.If you’re concerned about liability or want more peace of mind, you could ask the primary applicant for additional security, such as a higher deposit, depending on what’s allowed under Colorado law. 

When it comes to analyzing properties, I’ve developed a specific checklist to make sure the home fits both resident needs and operational goals:Square Footage: Ideally, at least 2,000 sq. ft. to ensure enough living space for residents and staff.No Stairs or Pools: It reduces liability and keeps the home accessible for everyone (this is just my preference).Corner Lots: I love corner lots because they often provide extra parking and outdoor space—both of which are critical for families and visitors.

If they want their money back fast like a flip then let them flip it and you buy it as a primary residence with a conventional or fha mortgage.

My current asset allocation based on age and risk tolerance not counting my primary residence is 70% stocks, 20% RE, 10% cash/bond type vehicles.
