Melanie- just sent you an invite to connect :) So I have two duplex in the Harrowgate area and one actually really pretty single family in Frankford. Neither of them are in fancy areas but I picked them because they were structurally sound, priced well as far as cash on cash return. Two of them had multiple offers the day they went on the market but I paid cash and had an awesome realtor who knew the area and helped me enormously. She handled so much for me being a remote investor and was worth the investment.
For my tenants, two of my units I partnered with a state run program that helps find housing for previously homeless individuals. They are an AWESOME partner and even though it was a pain and very frustrating to get it up to code, once it was there they pay me directly and they cover damage.
I have one inherited tenant that was a bit of a learning curve because he speaks zero english and has never paid not cash before and I certainly didn't want to be knocking on doors- but once we got into our groove and I opened a local bank account he just deposits the money in zero problems and actually is one of my favorites.
My other two tenants I used my realtor and I was SO picky. I let those places sit until I found someone with good credit, verifiable employment, and ability to meet all my screening requirements. It took a bit of extra time- but it was well worth it.
As far as major issues- honestly nothing was insurmountable - the biggest issues that I've come across has mostly been deferred maintenance from previous owners and having to put more money than I originally planned in at the start, but honestly I'm seeing that money in area appreciation and with the excellent cash flow (For example I paid about 65k for my duplex and now I'm getting 1200 a month for it)
We had some wood rot which was a little expensive to fix, but it was fine. We had people dump trash in our back yard once and I invested in chain link fence, we did have a few broken windows, grafitti issues, pest control issues but I try to just stay calm and just take it one step at a time. It's been worth it 100x times. I can't wait to do more!
