You haven't covered your tax situation which is critical. You want to move at least a significant portion to a tax advantaged account so it can grow tax free. You'll only be able to move so much every year. The remaining portion I would buy into stocks or bonds according to whatever plan I chose, but I would be sure to max out those contributions to tax advantaged accounts ever year. There are additional things to think about if you have other things going on, like a kid who's going to apply for student aid.
%% SURE is safer/Dave Ramsey 4 funds ; easier + cheaper is seldom a good combo. Concrete example SPY= much cheaper, easy @$155, 2000 top\ easy, cheap price did not do much to 2008 $ $157. Wonder how your guts would work , seeing $300drawdown to $150,000?? Most panic sell @ worst time LOL BUT even if you put into every year @ SPY or VOO top/ most likely do well over 30-40 years. Much more movement than REAL estate ; Dave[Realtor, radio] ramsey did well in RE, business , 4 funds, 30 years. Frankly ''losing out on a lot of compound interest'' assumes SEPT 14 is bottom this quarter\not likely. Congrats on RE sale......
%% DID we ''know'' SEPT was not the VOO-SPY bottom. NO, we did not ''know'' but SEPT is historically worst month of all 12. One of several reasons we suggested not putting it all in @ once Good old IBD article, put all the money in @ 30 or 40 yearly tops LOL in SPY or VOO, still did well over 30-40 years. SPY /VOO/QQQ had some good weeks also/up since SEPT 8. Another fun read study\ the few bear funds + how seldom they last or do well. BUT some inverse ETFs did well SEPT, tax free Roth account........
