Well An American Piloted jet liner and some of the better european ones and Quantas and Singapore airlines along with Cathey.. :)  you get the point though.. not common. tenants have no money to sue you generally speaking

I think there is a market for that....maybe just guys without wives on fishing trip who want to walk to bars and marina, or college students/younger crowd who want to be near the party scene, maybe airline staff.  

What if Maria's W2 doesn't require a lot of hours, say she is an airline pilot who sits on-call a lot, and is not needed much. 

If you're going to try and do the whole 'churn' thing and hold 10+ cards at a time, it may be more work then it's worth - you're better off using that time to focus on finding good RE deals :)I happen to have 2-3 credit cards at a time depending on which hotels/airlines i'm using - SPG Amex (for hotels), United Explorer (for flights) and my all-time favorite card, Chase Sapphire Preferred (for dining and everything else).

Congratulations Ruben on your acquisition.Have you heard of airline crashpads?

Of course, I'd rather just get in my car and drive around for a few hours (about the same amount of time it will take you to stand in line at the airline counter, then get through the TSA grope down, and look at some local properties I can put deals together on.

During the safety demonstration at the beginning of a commercial airline light, the flight attendents tell you to secure your oxygen mask first and then assist others.

Ive seen in the paper some realtors advertising airline tickets as referral fees so perhaps theres some ways around it.

Pro: Use a CC that gives you airline miles and helps you learn the costs of materials.

For example - if you want to be a commercial airline pilot - you want to find out what it takes (i.e. how many hours, ratings, etc.) to even get an interview with a major airline and work backwards and find the best path.
