@Rob Gleason congrats on your first real estate deal and MFR!
Think of the 1% rule as the bare minimum you should be shooting for on a rental property. If you cannot get 1%, run away. You will find some people say that .08% is acceptable, but I venture to say that if they really put in the effort to find 1% properties they could. In regard to achieving 2%, it can be challenging, and again some people say nigh impossible in metropolitan areas. I believe you can find 2% properties within two hours of all metropolitan areas, but they take work to find (direct marketing, word of mouth etc).
Accomplishing 10% ROI is good, but as you are discovering could be better. You will also find that all of the various metrics used in real estate investing are just that, metrics. Find out which ones you value most, AND fit your business plan. Use the metrics that are important to you to establish firm CRITERIA for buying properties in the future. This will help avoid 10% ROI, when you really should be getting 15%.
Also, one of the great things about MFRs is that they offer you a higher level of CONTROL than SFRs, especially with 4+ units. You have the ability to increase rents, reduce expenses and acquire even more units over time. Increase rents from $500 to $525, great! Reduce property management fees from 10% to 8%, great! Rent washer and dryers to your tenants for $30 a month, great! In essence, any positive improvements in cash flow have a more profound effect because you are operating on SCALE. While an SFR offers no scale, and there is only so many ways you can squeeze cash flow out of an SFR.
Again, congrats in your first deal! Awesome feeling isn't it!
All the best!
