Alternatively you could use Section 179 expensing here as well, but the expensing can't create a loss for the rental and may be carried forward.

      I am looking to get some advice on the best ways to buy land and create a food truck park in TX. 

Anyone know some good alternatives that are similar?

Where/what platform do my fellow investors like to acquire alternate assets?

The income from the property pays off the debt, while you get the tax deductions, equity build up and appreciation.As to why people pay cash, many don't know, like or understand other alternative investments. 

A simpler alternative would be a t bill or short term Treasury fund, such as SNSXX if you want the same liquidity as a high-yield savings account.

Is an alternative arrangement where the builder builds at a discounted rate, and then the investor handles selling the property + gets all profit?

(If they use their employees, their trucks, etc. this usually saves the investor quite a bit). 

It doesn’t always pan out as a viable option but I always recommend considering this so you know your alternatives.

Alternatively, if there is a real estate agent/ Agency that anyone recommends, please let me know.
