Reliable occupancy comes from the market you buy in more than the house you pick. Our strongest advice: invest where you actually understand the area instead of chasing a cheap out-of-state deal you can't see or check on. Work with a local agent who can pull real comparable rents and the typical time-to-lease for that submarket, so you underwrite on numbers instead of hope. From there, look for the fundamentals that keep units full: - Steady job growth and a diversified employer base, so one employer leaving doesn't empty your tenant pool. - Neighborhoods getting reinvestment, rather than whatever is simply cheapest. A low purchase price usually has a reason, and thin tenant demand is a common one. - People moving in for work. Those areas lease faster and turn over less. And be honest with yourself: no amount of research eliminates vacancy risk. Tenants lose jobs, stop paying, and break leases in strong markets too. Good screening and a solid location shrink the odds and shorten the gap between tenants. Budget some vacancy into your projections so a slow month doesn't sink the deal. A market you understand, screened carefully, is the closest thing to reliable that exists.
