LA is a tough market.

With MTR there are places where you can market to traveling nurses and medical professionals who are looking for something furnished for 1-6 months.

Often they will tell you what they're having a challenge with (like finding off market deals, a reliable property manager, etc). 

For those that are in the MTR space, what types of clients are you targeting?   are your getting traveling nurses, business professionals, displaced families, insurance claims etc?

I am currently studying for my real estate license and analyzing the local market.

It may be common in your market.

Study the market.

Please let me know if I can bring any value to you about the markets I've referenced.

Recently I saw the duplex that is DIRECTLY across the street from my property come on the market, and I would love love love to jump on the opportunity to buy this property as well. 

You can't arbitrarily decide that you don't want to allocate any of the proceeds to the portion of the property that will create Ordinary income recapture (thus can't be included in the installment sale treatment) - it should technically be allocated amongst all the assets in accordance with their fair market value at the time of the sale.
