We have a general idea of how the arrangement would look like, but we want to make sure we draft a legal document, if possible, among ourselves (to save on the attorney costs).

Personally I think it'd be a smart idea to bake some sort of clause into a house hacking lease that removes Landlord of such liability and asserts Tenants are aware of and assume the risk of covid-19 transmission in such a co-living arrangement.

They may have jumped to the wrong conclusion with you, but in market filled with cash buyers and over asking offers, they see less need to deal with unconventional financing arrangements. 

Depending on the lender, some may not be willing to work with you in this arrangement, so it's better to think through all your options and research any potential implications beforehand.

Are there any verbal agreements or arrangements between the current Landlord and Tenant?

Thanks NickNick, any business entity formed that buys notes won't be considered an "investor" it will be a business and licensing is extensive for residential notes, but still a license issue for commercial.Going in with your brother-in-law is still pooling funds and your arrangement may then fall under SEC requirements as well as mortgage brokerage activities.

They will help you figure out what you want to buy, arrange showings, show you the houses and help with the offer process.Mortgage brokers can help with getting the loan.
