If you are a conventional, FHA or VA buyer the loan most likely will not go through.
Some seller's agent thinks that by asking you to do it, it will show how committed you are on buying the house.
Remember Contingencies were put in place for a reason "to Protect you, the buyer" so be firm and make sure your Realtor protects you from getting in to a bad situation.
Ask yourself if you'd be able to tell if there were foundation problems, or the electrical was a hazard even if the outlets and wiring appeared to be OK? These are just a couple of issues that could arise after you moved in and pulled up the carpet, etc.
Good luck in your purchase!
In almost all of those cases, we were able to negotiate the purchase price down to the appraised value by leveraging our contingency removals.
As it was said below, it is not a black and white answer as every situation is unique and different, but in most cases, you should not remove your appraisal contingency unless you have the appraisal completed and know what you're working with.
If you need any further assistance. Do not hesitate to ask
Best to you
