You're trying to find a way yo monetize the opportunity however all I see is that you've observed a house and (anecdotally) connected with a lineal relative who expressed no interest. 

I really had no idea before but now definitely got so many good ideas.Sorry that I did not include all the necessary information, here we go:- the bottom unit is currently on month-to-month lease- the rehab needed is fairly basic (at least from my observation)- the property is located in PA, so cold winter for sure :(The challenge is I live in California and may need to rely on my property manager to handle the tenant turn-over.

Second, the rise of the internet has made it much easier for sellers to directly observe the characteristics of other houses on the market and to find recent transaction prices, reducing the informational advantage or realtors."  

I am currently observing an investor struggle with a long distance rehab of a flip in the East Lake neighborhood of Atlanta.

I don't think there are very many home buyers who walk away from the home of their dreams over GFCI outlets- if anything, what I have observed is quite the opposite!

Having set up the LLC himself, and having observed me correcting the address with other parties (eg, insurance binder), this isn't  a difficult thing that needs a hawk's eye.

While saving for the down payment, I'm observing the market and all its multi family residences.

I am in agreement with your knowledge and observations.  

Jana,  I would search Zillow for local rentals and observe the rates with and without garages.  

You should ideally have both and then observe the LLC formalities and respect it as an entity so that you get full protection.
