Are you sure she can’t sell the property? This seems no different to selling a property with sitting tenants – it may affect the sale price of the property but does not mean the property has nil value.
You would only take rent into account if the property is disregarded, for example if it is occupied by a 60+ relative of the claimant. If it turns out that the property cannot be sold, this is different to disregarding the property. You would still take it into account but the value would be zero. Any rent would be treated as capital as and when it is paid.
