we'd need more detail...would only be assuming the circumstances by responding...What is the situation? 

According to this website, Citi cards are the best for extending the warranty: https://thepointsguy.com/guide/best-cards-for-extended-warranty/.I read the exclusions on the benefits/disclosures brochure associated with this card, and the only thing I saw that wasn't covered similar to what you're referring to was "Items purchased for resale, professional or commercial use." 

This is an item that might be easily overlooked.  

Another item is the cap rate. 

@Daniel Rutherford  Before going into the finance details, will the on-line auction even allow it to be financed?

I don’t know all the details for them yet.

I might have some local referrals to send you to so feel free to PM me for details.

The entire cost during renovation might not have to be capitalized and can be expensed, but you need to talk to your tax professional and give him all the detail. 

That's not the answer I was looking/hoping to see but it makes sense since what I was contemplating doing was moving interest payments from my home (not deductable since I don't itemize anymore) to a rental where it is deductible.

The details will fall into place with the proper team.
