I'm going after a flip and likely will partner up with a brother of mine to share the work and down payment, and we'll be funding the rest of the deal with hard money.Do experienced investors recommend we start an LLC for this? 

@George Blower Brother or Sister-in-law be the guarantor tho right?

Over Thanksgiving, I was complaining to my brother-in-law about having to pay for our house every month and he asked me if I'd ever heard of "House Hacking."

He plans to call back once he talks to his brother, so hopefully he accepts.

@Trevis Kelley thank you for your service brother. 

Thank you Todd and Jake, Merry Christmas brothers.

I called my brother and asked him to go check it out for me.

I have teamed up with 4 other newbies(2 brothers and a cousin).

If it's a problem with the plumbing and significant areas of the flooring, walls, or ceilings need to be opened up and it becomes too disruptive to the tenants or hazardous, an offer to house the family in a hotel for the time being would be in order.However, mystery water soaking a carpet brings to mind an incident in one of our properties... the tenant's brother-in-law hooked up his washing machine and didn't secure the water exhaust hose properly.

The Springfield area may be a good area to explore my brother and his family are house hacking there.
