Visiting a tenant's current residence only works under some circumstances. My latest tenants, military, moved from another state, not affording me an opportunity to visit. However, the actual dwelling can be viewed on apps like Google Earth streetview. I have used this tool to check on some remote tenants. One prospective tenant's house was in my rental's neighborhood, down the street. The messy and cluttered front yard told me what I needed to know about them; no visit needed!
