We had something similar and had to pick a new countertop. In my opinion, this isn't the builder's responsibility, there are massive backorders in most industries due to COVID. I'd pick a new floor and possibly narrow it down to your top 2 or 3 as the new floor will likely need to be in stock and available to close on time. Alternatively, you could see how long your original choice will take for delivery. But unless it is almost ready to be delivered, I think timing will be tough. And it could trickle down to impacting your mortgage rate lock (if you've already locked that in) and maybe even cause the builder to force you to complete the contract or find a new buyer (if the delay is excessive). The builder is going to be focused on closing on-time. Depending on where you are located in the country, if the market is hot, someone else may be willing to buy your home at the same price or higher and willing to be flexible on flooring. The builder is going to want to prioritize closing on-time.

Alternatively, could you put in the most basic, cheapest floors and then use the savings on your flooring to upgrade to your first choice after move-in? In our new construction neighborhood many of my neighbors upgraded flooring after move-in, both to save money over the considerable builder markup and to keep the value from the flooring upgrade off of their appraised value (lower property taxes). This option is inconvenient because it delays move-in or you have to juggle your belongings during the install.

Pick a new floor.

The builder is doing what they can to get it completed on time and will provide help in the reselection.

Thank you jennsbabysky.

Thank you Jeffrey

Sorry for the bad news to follow. We have instances on this forum where builders will cancel the contract during the build and sell it the next week to someone else. The market is still hot. Pick an alternative and be prepared to pick a third choice.

It's not the fault of the builder. Building supplies are in short supply. The builder doesn't care what color or material is used. They just want a check in their hand. You must be prepared to go along. You are in the weakest position in this transaction. Recognize that and move forward.

Once the home is yours, you decisions are final. Right now the builder's decisions are final.

Based on a loan agreement, banks acquire real estate from the owner and transfer it to the borrower for use.

I am not sure what this has to do with the OP's question, but it is incorrect. Banks in the U.S. do not acquire real estate and transfer it to the borrower for use. U.S. banks loan borrowers money to acquire property and secure that loan with a lien. At no point is the bank the owner of the property and so it is never theirs to transfer.
