My recommendation is to just save the money you would spend on extended warranty coverage and apply it to hiring a professional service company that you researched and vetted yourself, once you need a repair done.Hope this helps.Ken

I have used lines of credit as down payments on properties before, and I also have used lines of credit many times to help me through periods of construction where costs over ran.

Most HELOCS have an interest only period in the beginning.

They will mail you a letter to let you know if you pass or fall, and then you will have a time period to make any needed repairs (30 or 60 days, I can’t remember).

Would it have to be vacant at close or could the agreement extend an additional 59 days after close as long as there is a signed document by all parties?

There's a decent chance you will sell or refinance before that period, so the buydown was a waste.

This is especially true if you're only giving yourself a 6 month "trial period."

The lease extends to March 2023.

Period.

We had to extend our closing to over 90 days due to COVID impacts when we moved from California to Alabama.
