Property taxes are due, but it will cost me ~$100 to put it on my credit card, and the best I can get with normal points is ~$80 back.
MrsTX was sent an offer for the Chase Sapphire Preferred. Spend $4k, get 50k points.* Plus 5k points to add an authorized user. Normally it would take awhile to get $4k spend.
Get new card, pay property taxes with new card. Done.
The math: Gain 50,000 points for spending $4k. 5000 points for adding a user (me). 4500 points for the actual payment. Cost: $100 extra fee. Going by cash value, that's $595 in points, minus $100 in fees. Net a minimum of $495, more if we choose a better redemption option.
And it's a really snazzy looking card.
We should do this every year. :D
*Points can be redeemed so that 50k points is $500 in gift cards, or $625 in travel spend.
