Savings on the rent will be about £40k, the main savings for them will be on the significantly reduced maintenance costs. There will still be some of these that they will pay at our ground but the costs at Odsal are enormous and have been for many years. Overall Bradford have been saying that they anticipate gross cost savings of £400k pa.
Whilst that sounds considerable it doesn't take into account any equvalent reduction in income which must be inevitable given that a fair number of people will decide that they don't want to travel to our place on a regular basis. What the overall benefit to them will be is hard to be precise about, therefore, but it should be significant, at least in the first instance. If they fail to gain promotion to SL in 2020 however, then the calculations may need some revision; they are gambling upon this and it is unclear how much is being sunk into this effort.
As far as we are aware Bradford have no big money man behind them, even if the costs from their original three years must have been considerable and, I would guess, exceeding their income. The whole sport will watch the development of their club with great interest, I'm sure.
