Problem with steady state in Iacoviello and Neri (2010)

I am trying to simulate a model with housing as a collateral constraint including both a consumption and a construction sector which is a simplification of Iacoviello and Neri (2010) . I get the error that ‘it is impossible to find a steady state’. I checked the model several times and I cannot find the mistake.

I attached the mod file below. Any help will be very much appreciated.

whc does not look correct. Check the equations involving it.

Thank you for you help but unfortunately I could not find any mistake in the equations containing whc.
