Aside from that, the Sellers are not required to sell it for the Listing Price; (there are many loopholes)
Perhaps you should enlist a local Realtor to check it out for you:
You wouldn't want to buy it without seeing it.
Sounds like you have done your homework!
If you are right, you should not let a moment pass and purchase this house NOW. The day after closing you can resell if for 'PLUS" $425,000! Now that is real profit.
You should buy it! NOW! $425,00 straight into your retirement account (Self-directed IRA).
Best of success to you.
