Tell me, exactly how do you propose that we make projections and forecasts and determine the impact of the "cram down " bill on the lending institutions, without the necessary data? The current home owners have yet to take advantage of the new provision, so the estimating the future impact, though possible, will most probably be highly inaccurate.
What we can do, on the other hand, is analyze the effect ( if any) the "cram down" provision, long available to investment property and vacation home owners, had on the lenders. Because that data is available.
