@Scott England I really appreciate you taking the time to give such a thoughtful reply! I want to give a few comments on the points you made.
1) Location: I completely agree that the surrounding apartment complexes effect the home value, rent value, and marketability. However, I realized that the apartment complexes are essentially offering me free marketing. The complex across the street has its leasing office about 100 yards from this duplex. This means that every potential client they bring to their property must pass by my duplex first. In my opinion, people would rather choose a duplex that is 500 sq ft bigger and has a two car garage over that apartment complex - or any other in the surrounding area for that matter.
2) ROI: I am not exactly sure what you mean when you say the Cap and CoC do not "correspond" to the age, location, and building type. I'm no sure what you would look for on a deal like this, but I don't think a 11.70% CoC is anything to turn your head at with $40k invested into it.
3) Cash requirement: $40k is A LOT to have tied up in this deal. However, the property next door (same type of duplex, same layout, same sq ft, sold by the same owner a month ago) appraised for $195k - which gives me decent confidence that I will be able to ReFi in a few years and pull the 40k back out. Also, the $380/month in cash flow assumes a property management expense. Since I will likely manage this property myself until I ultimately sell it, the cash flow will be more like $500-$550/month.
4) I have already secured this financing - 30 year at 4% fixed. I am working with a credit union back in Texas that provides exceptional rates. I agree that this will tie up most of my borrowing power, but at this point I am not sure how else I would do it. Even if I partnered with someone or used private money, it would create a monthly debt obligation that a bank would look at when I eventually would go to them for financing. I figured might as well us a bank first and then go to private money where it is less important what my debt to income ratio is and more important how good the deal actually is.
I really do appreciate your feedback, but I believe for my investment strategy at this point that this is a deal worth pursuing.
