Financing Kentucky One Home at a Time
I answer questions about financing real estate based on my decades of experience dealing with mortgage underwriters. This answer is my personal opinion, has not been reviewed or approved by the company I work for. I do not offer legal or tax advice, if you need answers from an attorney or CPA find one knowledgeable in your local market.
Will it happen again?
That is the REAL question to which only you have the answer.
Get yourself in position with a back up contract.
No, don't wait for the deal to fall apart and expect to be contacted. You will agent be "A few days late." Get the back-up contract signed.
The seller will not and should not violate the existing signed contract. That could result in EVERYONE being a few days late and a third party, presenting less complexity and liability sealing the deal.
Moral to the story: The early bird gets the worn.
Ask your agent to enroll you into the First Look option. You will pay market value but you will get a day or two head start. If you have learned your lesson, that head start should be sufficient.
Best Of Luck.
The best thing you can do is move on and find another property. The market is showing signs of slowing down, and future prices may be in your favor.
