Many good comments here, especially @Nathan Gesner's book recommendation.
Here is what I do for listing my properties:
Clean up and do all necessary repair/maintenance to make sure the property is clean, safe and functional. Tighten up the yard to boost curb appeal. Use a professional photographer to take good pics.
Then advertise it on Zillow, Realtor.com, and Facebook Marketplace. As a real estate agent I also advertise it on the local MLS but I rarely get a tenant from the MLS. Nowadays most tenants come from zillow and its affiliates.
When I get prospect wanting to schedule showings, first I talk to them on the phone and just go over the requirements in the Ad. You can count on most people don't read the description of your Ad so better to have a verbal confirmation before spending time doing the showing. I usually try to group all showings on the same day into one time window, like a mini open house so I'm minimizing my time spent on showing.
I use TurboTenant to screen my tenants. I have tried many third party platforms in the past and in my opinion TurboTenant has been so far the best. I've even tried RentRedi here, still didn't like it compared to TurboTenant.
Reasons:
Clean and simple user interface.
Affordable and effective background check. Their background check seem to be more effective because I get traffic violations as well. I feel many other third party platform who screen tenant background most time come back clean and sometimes in reality, it's not the case. I also check county court cases and see if there's anything open against them. Often I found stuff where the third party platform fails to find. And Turbotenant has been able to match what I find in the county. Not sure why.
The platform prompt the applicants to upload all of their documents. I don't know how does the platform do it so effectively but TurboTenant is the only place I receive all the attachments I want most of the time. Of course, if the applicant deliberately decides to skip uploading documents, then I don't get them. But I would say 90% of the applicants from Turbotenant I automatically receive a copy of their ID, paystubs or bank statement. Not the same case with other platform I've tried, I always have to ask them separately to show proof of what they claimed in the application. Not a deal breaker for me, just a feature that's really nice.
Lease, you can use standardized form from your state. For us, we used our own forms that's been initially drafted by an attorney and continuously tweaked by us over the years. We are very familiar with our state landlord and tenant laws and we review it constantly. And we learn from our past mistakes to improve our lease agreement. We try to set very clear expectations in the lease agreement and spell out responsibilities between landlord and tenants.
As far as payment goes, we use apartment.com for our automatic payment services but now it seems like TurboTenant has one as well and we are trying it out with our upcoming tenant in one of our units. You can also accept cash/check. You need to check your state law about accepting partial rent. For some state, accepting partial rent will reset the eviction process.
Lastly, learn every word and take it to heart about how to handle security deposit based on your state/local laws. Security deposit dispute is the most litigated cases in landlord/tenant court cases. I know a tenant, who moved to a different city, took one of my friends to court for a $300 dispute. My friend ended up winning but just a reminder to be cautious with handling security deposit. Dot your i's and cross your t's on this one particular procedure.
Best of luck to your Landlord journey.
