I don't know of any groups or partnerships in that area, but I would be interested if you found a group over there!

How would you start a partnership for investing in buy and hold BRRRRs.

They'd be foolish not to accept that partnership.

@Phil Rizzo....I recently listened to this podcast on BRRRRRhttps://www.biggerpockets.com/blog/biggerpockets-podcast-237-partnerships-brrrr-investing-working-full-time-ian-reeveswherein, the invester in Kansas City suburbs was buying and rehabbing for $41k and ARV was $70k (about 59% of ARV) so, yes, BRRRR can work in other markets.

I have lot more disposal income to contribute, but also wanna scale quickly. 3) does limiting partnership, but higher individual contributions, makes more sense even though we will have to move more slowly in the beginning?

Create a "personal captive" Qualified Opportunity Fund (needs to be a partnership or corporation -- not a single-member disregarded entity). 

A partnership might work but you need to be able to provide value to whomever is lending you all the money.

@Tom Canterino Partnerships and joint ventures are tricky.

There are a lot of moving parts and economic tranches of financing usually on the Federal, State, County levels along with private partnerships to make it viable. 

With knowledge and a decent network of people it becomes a matter of figuring out not just what those people in your network can do for you, but also how you can help to enrich those people.So with that I say, even if you don't hit your 5 million mark you will have developed some good partnerships and friendships and have the knowledge to start from ground zero if you did "lose it all"as far as investing, I would probably do a few flips until I could find a b r r r property.
