For me, it's basically a no brainer.
SUB: 250,000 MR
Points from MSR: $20,000*1 = 20,000 MR
Annual Fee: $695
3% Fee on MSR: $20,000*.03 = $600
MR can be cashed out, at minimum, at 1c/pt with business checking.
270K MR = $2700
-$695 - $600 = $1405.
In other words, 140,500 MR for absolutely free.
Then you have $600 in Dell credits, $400 in airline credits as gravy.
Edit: And this is the worst case scenario. If you have a Schwab Plat, you can cash out at 1.1c/pt. If you spend in the bonus categories, you earn 30K MR on the MSR. If you apply in December, you get $600 in airline credits, etc etc
