39, USA, 156K (after taxes) homeownership. 6months-2yrs (maybe pay cash- looking in 200k avg home area). High risk tolerance, shitty shitty credit (680?) (5k in old mostly medical debt in collections) holding 10k SPY about 5k tech & entertainment (I know not very diversified). 95k (and growing) student debt currently on hold (am in grad school for another couple yrs). And 20k left on my car loan.

Anyway, here’s the deal I wanna buy a house, sooner rather than later is the plan. But my godawful credit union gives me like 0.05% interest- and I feel like leaving it there is just throwing it down the toilet with ever increasing home values. So I recently started throwing $2500 into SPY every week instead as a savings account (I’m living frugally and can survive on my remaining 1500 ((after car payment)) a month).

1. How dumb am I? (I know dips and crashes can happen, but it seems like on avg it’s back at ATH in under a year almost every time). And I can wait it out if I really have to
2. And the real meat of it, should I be timing my deposits- waiting for red days etc. or does it sorta all even out as long as I’m throwing it consistently? Is eod better than open? Or can I just keep depositing every Friday morning, and not feel like I may be screwing myself from a better strategy?
