Much like at HUFC, Tisdale has seen his player budget cut as a result of relegation.
"The fact of the matter is we can't afford to pay what we paid last year for our players."
Tisdale also says the market for free agent players is stagnant at the moment.
"I think it's going to be a long summer of waiting," he added. "A lot of other clubs are in the same boat as us and holding their nerve, paying only what they can afford.
"I think there are a lot of players out there at the moment who are disappointed by the offers on the table.
"There are a lot of players who are waiting to find a better deal and a lot of clubs who are standing firm, not prepared to give a better deal.
"Ultimately, I'm going to get the best value I can and we're not going to spend more than we can afford."
