When my partner and I buy a deal, we want to be able to recycle our capital.

I don't "need" to see the cash flow in Year 1, but appreciation is a ton more risky - and I'm probably worse than the average person in anticipating RE cycles, hence a mix of CF and appreciation is desired. 

To be perfectly honest: when this comes up, half the time I refer someone to a quirky fellow I met a year and a half ago who answers HML scenarios same-day, the other half of the time I grab one of the random HML junk mailers out of the shred/recycle bin next to my desk that we get a zillion of per week.

Most of them are overpriced or they just recycle them and they reappear and go back on the auction.  

On a side note, there are companies that recycle mattresses.

When you do these do you use a lawyer for all of the documents every time or is this something you can keep in a drawer (so to speak) and recycle every time you do one of these?

Many of our tenants cannot, or will not, effectively sort their recyclables from the garbage (required here), so expecting responsible use of a garburator is unrealistic.On top of that garburators are hard on municipal sewage treatment facilities and, in many jurisdictions here, you are not allowed to install them in new builds or {technically} replace them in existing properties.

But if you would like to save a few bucks, recycle.

The biggest piece to the puzzle when you are in accumulation mode is recycling your capital.  

I don't know of any cheap source, but here's a business opportunity for someone: My county separates glass out for recycle, but no one buys it.
