If this project goes well I would like to be able to recycle my money some how and build another to keep this process going.

Karen MargraveThey were in the waste and recycling business.

If you have limited funds and need to recycle them through multiple projects, leaving cash in each BRRRR quickly depletes your capital.

The bottom line is the economy isn't distressed right now and it makes the most sense to do buy and hold somewhere, might as well do it in a place where you can maximize your cash since you're not buying to pull cash back out and recycle. 

I would love to be able to recycle the capital I put in to keep buying deals. 

Install costs are about 25K and it recycles the water during use with a small footprint. 

(However, I'm hoping to soon have my 10 "good" loans and planning to maybe go back and recycle my SFR for multiunits).Anyway, it seems like:-The cost of refinancing is well below the cost of selling and buying and acquiring another loan-I'm having to put down 25% already, so is it really that easy to get 20% down once you get to 7-8 loans? 

Yes, that is an approach and it would likely be a higher interest rate than your HELOC, but then you get to recycle the money.

I had told her, and my sister both who have very high valued 401K's that I expect a stock market and real estate crash in the next 3 to 5 years and they really should get out now and invest in cash flowing assets (because they both have over $1,000,000 I told then to put $1,000,000 into a life settlement investment paying 50% in from 2 to 5 years, and to just keep recycling that when it pays out, and to put another $1,000,000 into bridge loans that are currently paying around 7%  or they could invest in cash flowing real estate. 

I knew that concrete is usually recycled and crushed to make road base, so disposal probably isn't super expensive.
