@Charles A. Kayuha,
I invest nearby in Clarksburg, WV. This is a nice duplex! We typically set aside 10% for maintenance and capex, but we self manage so we save on that expense. In this area you will not have any expense for a realtor as the buyer. I'm not sure what your goals are with this property, but we have used a couple of commercial lenders. Rates right now are around 6.5% on a 20 year note. The commercial lenders we've dealt with treat the 20 year as standard, and they require 15% rather than 20% down. Needless to say, if you're buying this under your name, there are a lot more options. We just liked the security of owning our properties under an entity. Your numbers for property management look good for the area based on a couple of the local managers I've spoken with. I can also say your vacancy numbers are good. We have 16 units, and they are almost always filled. The only time a unit misses a month, it's because I'm in the process of filling it. Hope this helps, feel free to shoot me a PM if you have any questions about local specifics (lenders, realtors, contractors, management companies, etc.).
