Depending on where you are, local laws may make month-to-month arrangements less risky for the landlord. I just left an arrangement where I had been renting month-to-month at the same place for nearly 20 years. It was a congenial split. The same landlord has had to evict people on month-to-month and, being aware of local laws, gets it done in 90 days or less.
I’m not a landlord but I’ve worked for them, and I’ve been a renter my entire adult life. A couple points:
If you allow pets make it mandatory that they get written into the lease - type and number. The tenant is responsible for paying for damages by said pet(s). Get it in writing, that protects both parties.
Background check your tenants. Likely, applicants won’t be perfect but it helps weed out the worst ones.
If someone doesn’t have great finances check with prior landlords - you want someone who will prioritize paying the rent over getting a new Xbox.
Come around the property at least once a month, even if you have a management company - preferably a couple times, and make it random if you can. You want to nip problems in the bud regardless of whether it’s tenants or a worker at the place.
Leave some means for tenants to deal with emergencies in off hours - either call you, call a management service, or something. A 2 am plumbing emergency that can be dealt with immediately is a lot cheaper than water damage caused by hours and hours of running water no one can/knows how to shut off. For a number of years my spouse and I were the on-site people who got the 2 am calls for this sort of thing - just knowing where the shut-off for the utilities is located and being able to get to them makes a difference.
