Fix n Flip/wholesale will give you the quickest ROI, but also are time intensive and I know you mentioned you have an issue missing out on time with your kids.BRRRR/buy and hold are the best for long-term wealth-building, but you won't become an overnight success story with either of these methods.

I am also a firm believer in procedures because I naturally tend to be too caring with people and you have to remember that it's business.

They should also be able to explain their method and back it up with data.  

I'm also wondering what you all think the best method of paying for renovations is.

I apologize for the rookie nature of this question, but want to make sure I'm covering all of my bases.Thanks, Mitch 

What are some good areas in Minnesota to use the BRRRR method?

That by itself is great, but in my mind the long-term objection is to take that cash flow and invest it into ownership which creates cash flow, equity pay down, both forced and natural appreciation, as well as tax benefits.  

Personally the BRRRR method has worked well for me, it gives the option of getting your invested cash back, and you get the benefit of owning real estate which will pay you back in the end! 

If you hold a rental property long enough it's hard to make no return/negative return just because of the nature of markets and fiat currency. 

I feel like a cashier's check or a money order would be a highly safer and more documented method of paying for a deal.
