12.7% currently cash flow but 32.6% can if optimized Correctly.

And euphoria and optimism are high (as evidenced by  some comments in this very thread!)

MartinTake a look at running a "preference test" on Verify App http://verifyapp.com/tour/preference-testI use them for the work I do A/B testing and conversion rate optimization, I'm in no way affiliated with them. 

There are many reasons why the large down payment is not optimal.

This is certainly warming the water significantly, but still in need of optimization (with respect to flow rates for the recirculation system to optimize heat exchange) - hence the data logging.  

Optimally it will be cash positive day one, which is often possible with $0 down but if not people can put a small down payment in order to achieve this, or others just prefer to pay cash of course and see it as a very low risk investment, basically prepaying 25 years worth of electricity at an extremely low rate. $0 down financing has been the most popular option for about 7 years now though, replacing the lease which was popular in 2012.

"Bull markets are born on pessimism, grown on skepticism, mature on optimism and die on euphoria. 

Really simple and slightly stupid question where can I get started to understand how to optimize my website for SEO?

Esp. in dollar terms a few mistakes could gut your return so the risk is much higher and the return is often not worth the risk. 4) You typically only have so many great loans so putting it on a bunch of $30K properties is typically a much less optimal idea. 5) Managing these properties is a huge pain and good luck finding a great property manager who is making only $75 per property per month (at 10%) or less. 6) As you mentioned capex can eat you alive.

There are markets that do both and will do both if you can truly optimize the properties revenue and profit potential.
