I use a credit card that offers airline miles for every dollar spent.

Me and my wife (Kami) both work for American Airlines in Tempe as Analysts and we have 2 beautiful daughters!

I have aspirations of flying for the airlines someday, but I also have aspirations of developing a RE portfolio that produces around 10k a month so I can have a FI lifestyle and live out some of my other dreams.

When we have had to purchase supplies/materials for those rental units, we have been using our primary personal credit card to purchase those items (whoo hoo for AIRLINE MILES!) 

Airlines can deny a person certain kinds of emotional support animals.

I normally put in my analysis a travel budget of 500-700 bucks (you could do it for way less -  see Spirit Airlines......it wont be fun but it will get your there...someday!) 

I have mentioned this many times before but what do you think would happen to the auto industry if all vehicles had to be paid for in cash like many foreign countries.. that's why there are so few cars in many of those countries.. and what would happen to private aviation where light aircraft enjoy 90% financing for 20 years at 4 to 6% interest and there are tax benefits but they start at 400 k  and light jets that start at 3 million or light turbo props at 2 million.. yet hundreds of these are sold each year .. all because of credit.and just like commercial airliners many are leased and those leasing companies are buy 50 million dollar or 100 million dollar planes with credit not cash then leasing them to the airline.s   bottom line credit freeze's we see what happened. 

A bit of a slower start with the passive real estate investing than I should have, but I owned a business and also flew(fly) for the airlines.

HDQs for American Airlines/Toyota etc.)?

I also thought SeaTac had a reputation as being "blue collarish" but it reportedly is right in the middle of Seattle and Tacoma offering great path to progress and easy commute to Seattle (via rapid transit)....Alaska Air's HQ is right next to property and there are massive expansion plans, which looks to be a plus...On the other hand, I cannot help wondereing how many potential tenants want to  next to an airline construction activity and a casino.
