I completely agree with John Mireles. I purchased my first rental almost 3yrs ago and really embraced the "a good rental will attract good tenants" mantra. I spent time searching for good deals on attractive light fixtures, fridges and dishwashers, flooring, bath/ kitchen fixtures, door handles, built-in bookcase, etc that would give my units a unique and quality feel to them. The last thing I wanted was a property that wreaked of home depot.
It works as well. I've had 3 tenants (first stayed for 16 months before buying a home of their own, the 2nd lost his job so moved back home, and the 3rd will likely be there for 2-3yrs if not longer) and 2/3 have been what I would call "model tenants." All of them stated that the attention to detail and quality of the unit were the reasons for choosing to rent from me.
Sure, I spent a little bit more on the remodel, but it's a home a would personally live-in and it has attracted quality tenants for me. I've never had to chase rent, never had to complete any repairs due to my tenants, and overall have had no problems. In fact, one tenant actually refused their deposit when I tried to return it! How many landlords can say that?
At the end of the day, don't take any shat from people and provide a high-quality product with excellent customer service. If not your results will suffer.
