Worst scenario of backing out an accepted offer

[Terry Z.]

So I have a house under contract and I am the buyer. Due to ongoing virus situation, I want to back out from the sale so that I don't over leverage and have more cash reserve in case anything happens. However, the process has passed the inspection stage and just waiting for loan to approve and it will approve eventually.

If I insist back out and seller sue me over that, how bad it will get to? I am trying to see the worst scenario. There is no earnest money in the contract.
