And how do you typically structure those deals to make them a win-win?

So I never turned people away simply because they don't meet one or two criteria.

(as if they do not get what they need and run out of money then chances of winning a suit are nil)3.

It's simply overwhelmingly nuts. 

If not, then the path of least resistance is to simply adjust your vision so it fits better into the lot, as-is. :) A zoning change can take up to 6 months, approval isn't guaranteed (despite Aldermanic support), and potentially cost a lot of money (architectural site / floor plans & dimensioned elevations, zoning attorney, holding costs, etc.) 

If you are simply buying for a lifestyle investment, then you have much more leeway in what/where you might consider buying.

You’re simply using some of the money you’ve already saved for your purchase to show the seller you’re committed and serious about buying their house.

The statement above simply doesn't make any sense.

They are $1100 we get for about half price so its a win win.

You can go the free route which does take some time, door-to-door, cold calling, and simply messaging buyers.
