What they don't tell you about Credit Card travel hacking

 So I'm a fan of credit card hacking.  Which is signing up for Credit Card to get the award bonus and using those bonuses and benefits to travel for near free.  I recently did a driving trip with my kids to see my Grandparents.  We covered 5 states over and stayed for 6 days.  Outside of gas it only cost us 330 to cover 3 adults 2 kids and 2 dogs. Not to bad.   

All these sites that dedicate themselves to travel hacking like the points guy or nerd wallet don't tell you about business cards.  Many of the reward/Fi sites always talk about is levering business cards. They not only have great bonuses, but don't count toward your Chase 5/24 limit.  Signing up for a business card is easy. You provide a justification. They can range to an established business, blog, to selling something on ebay.  Now what they don't tell you if that these business bonus are usually big, but require a higher spend like 15k in 3 months for 100k points and the big hit in the face is they can give you a very low credit limit like 5k.  Which mean you have to keep paying off you credit card constantly to free up enough credit to get to the 15k.  Ok that isn't easy, but during the right time of year it can be. Like paying taxes, car insurance, or paying school tuition. But then again you have to keep paying off the card all the time. What a pain.  So if you want to go down this route be careful of this issue.
