BRRRR strategy or value-add & 1031-ing are the ways to move quickest, but it's still going to take years. 

I've been doing build to rent off and on (when I can find great deals on lots) since 2010 and it's my favorite strategy.

A recent post that I wrote discussed exit strategies on a property that we’re converting from a 2 bd/1 bth to a 5 bd/3 bth.

There are four areas of focus to a buy and hold strategy: Purchase for appreciation and no cash flow; Purchase for appreciation and cash flow (this is what we all want...do this as much as possible); Purchase but receive no appreciation and little to no cash flow (worse case...don't ever do this); Purchase but no appreciation and cash flow.From your posts it sounds like you are in the situation where you are getting appreciation but no cash flow. 

The lowest risk strategy would likely be finding that B/C property in stable A/B areas.

Any tips or strategies for investing with partners because I haven't really seen much on that topic?

Thanks for this strategy.

I came to BG to see if there are any reviews of this guru's strategy. 

My strategy is to do a lease-option on the property. 

@darrell welcome I am fairly new to investing looking into the buy and flip and buy and hold strategies.
