What kind of advisor should I be looking for if I'm not currently in the market to buy or sell, but just need personalised advice on a long term financial plan where property will play a major factor?

I am single and reaching the life stage I should really be considering moving out of my family home and purchasing an HDB flat under the singles scheme. However, my plans are complicated by the fact that my family lives in a landed terrace house, which I stand to inherit a share of.

​

I have lived in this house all my life and it is worth more to me than money. I am being perfectly serious when I say I would not part with it for any amount. However, I am also aware that, holding onto it, it will probably become a financial liability. It's one thing to give up the opportunity to earn, and another thing to be in a position where I am actually bleeding cash.

​

I would like to speak to someone who can help me figure out whether I am being an absolute idiot, or if there is some way that I could make this work out, even if it is suboptimal.
