Purchase 2 used SNOO smart baby bassinets for ~$1000 each and rent each out for $75-100 per month for a year on average. Sell after a year for at least $750 each (low end). That's 65% return on investment in one year.
Obviously this isn't scalable but if you're working with $2,000 and willing to actively manage this is doable.
Only know about this because we are considering buying one for two months and then selling it.
