A whole house is much more work to get rid or the smoke odor.  

@Randy KinderA house hack calc will be the same, except you are one of the other tenants.

What’s your house-hack buy box?

The key is having parent co-signers, clear house rules, and reliable maintenance contacts since turnover and wear could be higher.

Wouldn’t house hacking reduce returns for a passive investor or lender?

For there to be a crash there has to be panic selling and as the economist is quoted, homeowners are just choosing to stay put because they are in great financial shape and can afford to stay.

I am considering offering tenants a lease option to purchase the house they are renting.  

For the housing market, higher rates mean mortgage interest stays elevated, squeezing affordability which reduces demand.

Before you decide to house hack consider consider what your long term goals are. 

We call it housing affordability.
