<prompt> Human: Hello PF. Im about to receive quite a big chunk of inheritance from a parent who passed away when I was younger. The money was looked after by my financially savvy grandparents, who put it into an investment portfolio and its apparently done very well as Ive grown up. I dont know exactly how much is money is there now and this apparently changes day-to-day with the risefall of the stocks and shares its in but supposedly its around 200k. Theyre passing it over to me soon, due to their age.Im in my mid 20s now, with a 150k mortgage - a good salary - and no other debts. Im wondering what would be best to do? Continue with the investment route and benefit from it later? Clear down the mortgage, freeing up my salary to build up by own savings. Potentially use whats left as a deposit to get a second property to let. Something else...Ideas would be appreciated! ThanksFurther details. Mortgage is 25 years, 4 years fixed 3. The investment has made more than that but Im not sure what stocksbonds its in exactly - but the last few months has been stagnating from what I gather. Annoying thing is that to transfer it to me, it ALL has to be withdrawn, taxes and fees paid.  <response>: I added topic flair to your post, but you may update the topic if needed click here for helprpersonalfinancewikiflair.You may also be interested in:- Windfalls wiki page- I have X, what should I do with it?- Whats the best way to pay down my debt?I am a botrAutoModeratorcommentsq11puwhat_is_automoderator, and this action was performed automatically.
