Well, really, the elegant way is to have the ID in the URL, and GET
it. It's not great practice to use POSTs when a GET would do, simply
for comestic reasons.

Is there a particular business reason you can't have the ID of the
property in the URL? If it's simply that the URL doesn't look pretty
with a querystring attached, you could make 'leases' a nested
resources, so the URLs could look like this:

/properties/1/leases/new

If it's genuinely unacceptable to have the property ID in the URL,
then you will have to send it as form data in a POST, yes. If you want
to avoid JavaScript, but still have the element look like a link
rather than a form submit button, it's possible to style buttons as
links:

but this is starting to look like a hacky solution to a non-problem.
Can you elaborate more on what you're trying to achieve?
