I see this is posted in the house-hack forum so I'll make the assumption that you want to owner-occupy your next investment.To work more hands-on, you'll want to spend time searching for deals, analyzing deals, and networking/building a team.Before your property search, I'd recommend speaking with a lender to find out how much you'll qualify for.
