However I do not pay the entire mortgage it’s divided evenly among 3 of us(brothers/partners).

Stay over parents, friends, uncles, aunts, brother whoever that can accommodate you for free for about a month. 

My wife and I expect to need to help support my brother for life (ours or his). 

As California residents though, you will have a hard time escaping CA taxes. 

I really look forward to hearing what you all have to say about this one.The backstory: My brother and I are best friends and great business partners in general, when it comes to most things.

I would suggest living there for at least 2 years because this may entitle you to escape capital gains taxes (consult an accountant or attorney just to be safe as I am neither).

That would require a special easement and without you may absorb quite a bit of liability in the event a tenant or child cannot escape from the room.

Most people lock up contracts, use escape clauses and low EMD's, then market to some buyers list and if they get lucky, actually close on the deal via an assignment of contract, and get paid.

My brother in law does unsecured loans he will probably be willing to lend you something on the equity but it wont be cheap.

I got some money for down pay, my brother got the loan and we are forming llc for this property and hopefully more soon.
