I look forward to speaking with you soon. 

I'm very early on, NOT actually engaged in searching for the a building today.My COH will be $500-800K, I want to be totally involved with every aspect of the transaction, the ownership.I will create a high-quality place to live, a destination to be desired.In your opinion:What are the questions I should be asking?

If you have already contributed to a tax advantaged account, generally speaking, your "job" is to get that money to make the most money.

The only subjective area is just how much you can maximize the travel benefits (assigning a dollar value to your points) and how quickly they will be devalued by the travel companies (it is inevitable like inflation, but how much and how soon is unknown)Very generally speaking, the best cash back cards provide better rewards than travel cards, however signing bonuses tip the scales in favor of travel cards for the first few years.

But be careful, everything gets lower quality as you move west on the map.  

Seems like for every quality REIA, there are 2 lack luster ones in the same market.
