Another thing is, YOU, the buyer, have the right to make the offer at ANY price that you choose. And, the broker really should be willing to at least PRESENT your offer to the seller.
Yes, it is true that the broker gets a bit more commission on a higher price, but we are typically talking about a commission that is a few percent more, at best. So that shouldn't hold back the broker. And it is true that they might not expect or believe that the seller will accept the offer. Maybe they are right, but what does it hurt to try? Sometimes, a buyer may just be tired of waiting, or might have particular, individual reasons, for accepting a lower offer. So it hurts nothing to present it. And if they make a counter offer, as a few of the sellers I bought from did, then you can choose to accept that, or move on and try somewhere else.
You never know until you try.
This isn't from DVC, but is an example of how real estate can work. I once looked at a house in a particular neighborhood. We wanted to move there, because my wife's sister had moved there and my wife wanted to be close. I made an offer that was low, but, based on the market, I thought it was reasonable. The seller soundly rejected it. So we went away. But then, within 4 months, another house, just 3 doors down the street, came on the market. It was worth at least $150,000 more than the one I had offered on before. BUT, I put in an offer for $25,000 LESS than I had made on the other house. The real estate broker said our offer would NEVER be accepted. I told them to put in the offer anyway. Well, it WAS accepted. Turns out the seller had reasons why they just wanted to sell the house. So, I moved into a better house than I had originally planned, at a LOWER price. We still laugh at that, every time we pass the house down the street that we originally tried to buy.
You never know until you try. And that is the way it is with DVC. Tell the broker to present your offer and wait and see. And then hope you pass ROFR.
