After conversations with numerous on your lot builders and a solid understanding of the work load I would take on, I started looking at land in an unrestricted, massive resort community.

For Deals stream are the 2 websites mentioned above (Land Geek & Land Modo) are the best in market for raw lands, or there are other big players known ?

What's more important is knowing what your goal is (immediate appreciation, long term cash flow, passive investments, et al) and then the avenue or "what to do next" becomes more apparent.I assume as a pro soccer player you may travel quite a bit, so anything you decide to do will need to be managed by someone other than yourself -- you can't be in Memphis and try to fix a broken window in New Jersey, for example.

This makes sense at the institutional level, where some players have bylaws that mandate they place money only in certain parts of the capital stack. 

I stay away from the condo or commercial markets.I'm resorting to the off market and the probate roll to try to find a decent deal.

I live near a ski resort in Colorado so labor and material prices are some of the highest in the country.

Scottsdale has the resorts and nightlife (hotels do a lot of research so you can see where they are building to understand where vacationers visit). 

For example, if you're looking to attract tourists, consider properties near popular tourist destinations such as casinos, ski resorts, or water parks.

It also has a smallish ski resort in my town (Mullan, ID), another ski resort 20 minutes away (Kellogg, ID), as well as snowmobile/other winter activities draw in the snowy season too.

Since I came across some multifamily properties, and today is the first time I managed to use my pc since I last posted (not working right on my cell phone), may be a good opportunity to ask your opinion (and anyone else who happens to read this post, please feel free to share your thoughts), would a property in a "seasonal" location, i.e ski resort be a good investment whether for short term rentals i.e Airbnb or long-term one.
