<prompt> Human: Really interesting to look at my post history. 3 years ago, I was asking what I should do with 40k in cash. Ive been saving a large chunk of my pay ever since, and three years later, I am now sitting on 250k in cash and 110k in 401kRoth IRA. Goes to show that perseverance and dedication will add up!I work in Manhattan making about 300kyear, but no knowing how sustainable this is and would like to invest in a condo in Manhattan, as well. I will have about 300k come December and my SO currently in training so no significant income will be able to invest about 300k, as well. We are looking into one bedroom apartments in Manhattan in the range of 1.2M. Yes, I know thats a lot, but its Manhattan, and wed like to live in a new building. We plan to live in the apartment for about 6 years, and then hopefully rent it out for investment; currently rents at 4.1kmonth and then move to the burbs.So heres the question I pose for you: we are thinking of down paying half roughly 600k, and thus will be borrowing 600k. Are we crazy for doing this for a ONE BEDROOM apartment? Is this home out of our range? Or should we down pay less and use the cash for something else?  <response>: Obligatory warning to not go into a co-ownership situation with an SO without the appropriate contract that stipulates how you handle things if you split up.
