<prompt> Human: My mom 57 and my dad 60 just split up. Theyre looking to sell the house and will make around 160,000 off the sale. My mom runs a business, maybe makes 20k profit per year. She also has an agreement with my dad where she has a separation agreement where he pays her around 1200 per month. She has not talked about retirement or anything. We live in Canada, if that makes any difference.She currently is renting, but has asked me 30 yo, approx. 45k per year if I wanted to go in on buying an apartment with her. Of course, that would put my name on the property. I would not be paying half of it; she said we could talk about how much I was willing to invest per month. Shes excited by this idea, but obviously something like this should be thought through properly. Shes only talked to a mortgage broker, who of course gets her hyped up about owning her own place. Here are my concerns;1 I have a brother. About inheritance, would it be fair or just of myself to claim the entire property if my mom passes? Even if I just put down 10 of the monthly mortgage payments, it seems like a bit of a hassle if that just means Ill inherit 55 of the propertys worth 10 of my investment, then 45 to me and 45 to my brother.2 Should she be buying property near the age of 60? Im not really sure how much she has in savings for retirement, and considering how much she was worried about the amount of the separation agreement from my dad, Im guessing its not a huge amount. I will ask her about this though. 160,000 would be a huge boost to retirement savings, and Im not sure if it is wise that she wants to just use this to pay off x amount of a new piece of property.3 Is this a good of an idea for investing for me? Or would it be better to just take the amount I would have spent on a house and invest it elsewhere? I have several monthly investments already in place.Any knowledge or red flags you guys could point out would be appreciated, thanks!edit: I would not be actually living in the house with her.edit 2: Thanks for all your comments. I think, instead of talking to her about buying property, Im going to speak to her about retirement and finances. I was under the idea that if my name would be on the property when she passed, since it would be mine fully, and I only paid 10 of the mortgage each month, it would be a really good return on my money in the end.  <response>: There is no better way to ruin good family relationships than getting money involved. Investing together is fundamentally different from being family. If your mother hasnt been able to talk about retirement with you yet thats a big red flag. She should have been discussing that with you for a while now. If your mother cant talk about that with you voluntarily, she is not a good person to have a business relationship with. Can she save enough each month to afford the mortgage, insurance, taxes and repairs that come with ownership. What are her savings habits? How does she treat money? Could you be blunt and get her angry if she was not being smart with the property?This is also probably terrible investment. It would definitely be your own if your name is on the title, but do not in any way think of this as an investment. Investment means that you have gone through all the paperwork with a fine toothed comb and have a legal agreement ready to go. It really sounds like your mother got talked into things by someone who was able to soothe her fears of retirement and providing for you after her death. I would focus on understanding her financial position first, because right now theres too much info you dont have.
