I concede if someone continued to be late over 20 days, the fees start getting pretty high.

I will concede it's the right call sometimes.

If we can agree that relative to utility and performance an electric vehicle is much more attractive to a user/consumer, then we have to concede that the only limitation is the price. 

My realtor made the point that if the seller concedes this on moving the mobile home, that will be money they probably won't concede elsewhere in the deal (like by lowering the purchase price, etc.).This would be our second purchase with a VA loan.

@Bill Rich,Ok I concede,From the original question: Why would a seller not accept an FHA loan?

Is this something I should concede to or keep the sellers feet to the fire and make them pay for it before proceeding? 

The seller conceded and our earnest money was returned.  

He will not concede anything else because he came down 40K on the list price.  

@Jasmine Hu I’ve conceded VA also.

Personally I have never had to pay taxes on any of my RE holdings.Yes, I have already conceded that in the scenario you describe, you do eventually catch up.
