Last time I sat down with my mortgage broker (admittedly, in Australia where the private equity scene is abysmal) he advised me that none of the banks would take into account my shareholding in private companies as assets. Essentially, it's a crapshoot for them to justify the valuation so they aren't willing to attempt it. I suspect there's a point where they will, somewhere before 'publicly listed companies' (which publish the market valuation on a moment by moment basis), but it's likely to be within established industries (partnership in a law firm, for example) not near my situation or most tech startups.
