Anyway, when it sells, I will have all the money from it to invest. I currently live with my daughter in an apartment she owns, and we will stay here for at least 2 1/2 more years, and after that it depends on where she is going to study etc. But I'm not buying anything new now. I also own a large woodsy lot which is for sale, and the money from that would, or would almost buy me a studio apartment if and when that eventually sells. That money I could keep in a high yield savings account where I could access it for the purpose of buying a small home for myself when that becomes necessary. Or something similar where the capital is being preserved. DD is just turning 16 so it could be many, many years in the future, as she doesn't seem like the type to want to live alone very soon after turning 18. But who knows for sure. It could be in two years, or it could be in ten years. And I can always rent a place too (one option is to ask if DD's dad would want to buy an apartment and rent it to me).
When the house sells, I will have around 300K to invest. How would you allocate it, and what timeline would you use for buying stocks etc?
For two years from today I could let it compound, but after that I may need to start withdrawing, depending on what the situation is then (DD turns 18) when it comes to the living situation, income from work and so on.
I don't need to necessarily preserve the capital as an inheritance, DD already owns an apartment and will inherit quite a bit from her dad, and perhaps something from her granddad pretty soonish (he is not doing well :/ ).
I'm 49 and I would use the income from the assets to live between ages 51 to 68 so 17 years (19 years from today), after which the social security benefits kick in (but who knows, they may raise the age again before that) and it will be the minimum for me, something around 600 e net / month.
I do have some income from my work (I'm an artist) and I'm trying to be more productive, thus being able to sell more of my work, but right now I'm not counting on that, or any other business income. So for the purposes of this, let's not count my work income at all

In total, my assets are about 80-100K in the woodsy lot, 300-330K in the house and lot and 30K invested elsewhere. So 410-460K total. I'm going to sell my car after the house is sold, but it's only worth about 4K or so and I will keep some of that in emergency cash (and probably take a combined business and vacation trip).
I'm thinking mostly low cost index funds and dividend stock picks, but I'm not sure about the purchase schedule. Is it better to get the money invested pretty fast for maximum compounding, or spread it out to reduce the effect of market highs and lows? Any other advice?
