You've mentioned that your wife works late hours, that must mean she has some time in the morning. You can get her on board. In my case I am a housewife with 3 small children, my husband has more than full time job, he is on salary, so work takes up a lot of his time.
So basically, I took it upon myself to listen to BP podcasts, ebooks, reading forums, researching the market in the areas we are interested in, reading landlord/tenant laws, looking through MLS, talking to agents. I don't consider myself an investor, just yet. Nevertheless we managed to buy 3 duplex since 2016. And we do manage them ourselves. I create rental ads, checking credits, reviewing applications dealing with tenants. And my husband does repairs whenever he has time.
And did I mention we both came to America some time ago with a little cash in our pocket, no relatives, no friends. If we could do it you can do it too!!! We are here for any advice you might need. Start small, dream big!!!
