You are what is referred to as "low hanging fruit."

Rather than saying "we don't do that type of loan," lenders sometimes instead say "we'll do it, but only if we can juice up the profit margin to something absolutely ridiculous."

Most experts and economists feel there is some more juicing of the economy to be squeezed before it runs out.Just remember when it does go down some  prices might get cheaper but lenders also start tightening LTV's and amount down.

I am glad to see you have a fruitful investing experience so far in Rochester NY. 

Many managers, it should be noted, will disagree with this policy, arguing that significant debt juices the returns for equity owners.

I’m looking for ideas on how to drive as much revenue through each of these properties and the empty land seems to be the lowest hanging fruit.

But in the interest of transparency and ethics, I feel you're better off seeing your job through to completion and getting the fruits of your labor. 

I don't think we'll go through the hassle again as the juice is not worth the squeeze. 

There will just be more low hanging fruit in the downswings.

You don't necessarily want to stand on the dry bank and then try & divert the stream to you.But as far as effort & startup costs, renting out dirt, portable containers, and then building permanent units is going to be progressively more expensive, so estimate the potential revenue with each of those options to find out if the juice is worth the squeeze.And of course as @Rachel H. said above there's more than just the financials - you're going to have to get P&Z on board, hearings if you're changing land use, possibly environmental testing, geotech surveys, etc.Best of luck to you!
