Financing tricks? credit card promos for property taxes, any other tricks?

Around this time of year I think about if getting a new churning/promo type business credit card is worth paying my property taxes with. Applying now is best to have it ready to pay January taxes.

• Chase Ink Business Cash
  • 0% intro APR on purchases for the first 12 months
  • $750 bonus cash back after spending $6,000 (e.g., property taxes) in the first 3 months
  • $0/year
• Capital One Spark Cash
  • $1k cash bonus on $10k spend in 3 months ($2k bonus if $20k spend)
  • Unlimited 2% cash back everywhere
  • $0 first year, then $95/year
• Amex Blue Business Cash
  • 0% intro APR on purchases for the first 12 months
  • 2% cash back on all eligible purchases (up to $50k)
  • $0/year

Amex is better for larger rehabs (instead of using it for property taxes).

Maybe do more travelling in 2027… then I'd pick this one for my taxes:

• Capital One Venture Business
  • 100k miles after $10k/3 months
    • 3 trips to Miami for two
  • $95/year

Any other welcome-bonus credit cards you've used?
