@Soomin Kim Of course! I bought the property with a tenant in it, so it was easy to just reach out to her and tell her she would be paying through a different system now. We use Cozy.co. It's the best one I found from doing my research and it's free for the landlord as well as for the tenant as long as they pay with a debit card, not a credit card. Whenever she needed repairs I would either ask people I knew in the area for a reference or I would Google a company and ask for quotes. She had two issues: the AC was blowing hot air and a pipe busted in the back yard. For the AC I asked my realtor and she gave me a recommendation. For the pipe I used the company that has emptied the septic tank before I bought the property. All companies let you set up and pay over the phone so I don't have to ever see them. The tenant let them into the property.
Now in July she abandoned the property. At first she just didn't pay so I used the attorney that closed on our house for the eviction. But when she emailed about abandoning then we were able to cancel the eviction. I happened to meet a contractor on BiggerPockets that cleaned and fixed up the property for us. Then I emailed a bunch of Property Managers and asked only about their listing services. I ended up choosing one that was recommended by my realtor. He went in and took pictures as well as edited them and listed the property for me. He is showing the property and will handle the credit and background checks of the tenant. They usually charge first month's rent as a fee then I will continue to manage myself. The managing part is not hard at all. I think we went through the worst possible scenario 5 months in. If you're willing to deal with missed payments and just being on top of tenants, then it's not so hard. If you screen the tenant well then you should have less issues than I had. When there is a maintenance issue, Google is your best friend or get recommendations. Oh and for the lawn I also Googled it and use yourgreenpal.com which is a site where lawn companies will bid for your lawn then you have a schedule that you can manage online. They mow the lawn and send you pics for approval.
We bought the property already knowing we wanted to self manage from long distance. Shortly after I read this book and highly recommend it. I got it from Amazon. The author lives in California where it's also super expensive and has done all his flips and rehab/hold investments out of state and sight unseen!
