Insurance being cancelled with tenant in place

[Brook Rieman]

We purchased a run down property last month for cash with intention of making it livable and renting it. There is a HUGE demand for rentals in the area and we had over 100 inquires by prospective tenants in a matter of days. We rehabbed the interior and got a tenant in place (lease started June 1). There are issues with the exterior (rotted wood around the windows, needs roof/gutters soon, new windows, siding). As soon as we bought it, we insured it with our usual company. Now, one month in, we were notified insurance is being cancelled due to condition of exterior. We have plans to update these things over the next year but not right at the moment as we are currently navigating purchasing a primary residence at the moment. Do we have any options? Is it possible to get just liability insurance on a rough property? It was cheap enough I think we would be willing to skip replacement if that was an option. Our own insurance company said it’s too late now, even if we managed to make all of the repairs in the next month (not possible anyway due to timing), they probably wouldn’t re-insure. Anyone have any ideas to throw our way?
