We need to forget about the £13m price tag for the Kassam. That went off the table years ago once FK realised that there was a significant opportunity to develop the site for housing. A more realistic figure would be around £25m+ for a tatty old stadium in need of development and without the additional revenue streams that would be needed to cover the costs of running a football club.
So, as
@Yellow River has said, we are left with two real options.
Build a purpose built multi-usage stadium, with hotel, leisure/retail facilities, conference centre, giving the club full control over matchday revenue and paying a peppercorn rent etc., whilst allowing the investors to benefit from all supplementary revenue (which would be significant).
Or, maintain the status quo with a lease agreement that may be improved to give a slightly better deal but will ultimately leave us needing to sell a couple of players per season to be sustainable.
I understand the reservations people have with building a new stadium, and how that seems to be miles away from our day to day operations, but the 'big hitters' on the board are not here for a long term lease deal. And whilst there continues to be nothing coming from the board, that really doesn't mean that nothing is happening. With everything that has happened in recent months it would have been easy for the board to have come out with a statement that showed their work to date on stadium issues, but they have maintained professional confidentialities, which may be frustrating, but actually shows how seriously this is being taken.
