So having an alternative option is always best.

Not the worst alternative. 

We also have zero RE investing experience, so we would be also be the much safer and easier option than having to manage a long-term rental. 

BUT, How about an alternate scenario?

But then I think about other alternative assets like art or gold... you must hire a broker to sell your asset? 

I also know that a duplex, while slower, is the safer, more conservative approach and on my single income.Either way, for the second property, said another way its like small steps every 16 months or bigger steps at 32 months based on my current saving rate.

You can also find some online courses through some junior colleges that might be a better alternative.

Examine your alternatives for financing, including low-down payment conventional loans and FHA loans.

Alternatively you could live in the Jr.

An alternative lender may offer better leverage but will be more costly.
