Should I start? or have I already.

[Tim Aiken]

I have been interested in investing in Real Estate, I am now in a situation that may be the right time, but a bit out of the ordinary,

I live in North Carolina, I have mortgage on my house, with the passing of my mother I am now 50% owner of a house in Royal Oak, MiMy disabled brother lives in the house and will stay until he passes, I manage the house including all bills, repairs, and taxes, he does not pay rent and is not expected to do so, so my question is should I consider this a real estate investment even though there is no purchase or rent, can this be a tax advantage? or other step to me stepping into becoming a real estate investor.
