So, rainforests are being cleared away to plant palms for the oil.What I do think holds promise is algea based biodiesel.

I know the formula is Rent/2 - Mortgage = +/- cashflow.

But it is only an edge if it's used.By systematically collecting just a few local demographic statistics (job growth, population growth and income) and property performance fundamentals, we can get ahead of the curve.

Remember I am a science geek so everything has to have a formula.

For years I have not known about these formula's and for years I have not made much money.

Look for things like deferred maintenance on plant and equipment, disgruntled employees, being too short staffed in order to make the bottom line look better.

After that came a home on 20 acres planted to alfalfa that I renovated and moved into, and I partnered on a commercial building with my broker, with a couple more in the works.My interests include farming, cattle, horses, hunting, fishing, poker, and R.E. investing of course.It is great to meet all of you and I can tell this is a classy site, glad I can be a part of it.

They all seem to be losing over $100 a month using the Rent/2 - PI Mortgage formula.

Never let anyone get ahead of you.

I believe we will see significant longterm (10-20 year) appreciation that will supersede any monthly losses.Thanks for any further feedback.By the way using the formulas you put together one would need to pay about $100k for a duplex in order for it to make sense but there is no such thing on the market.
