[Bryan Nwokem]

Hey Y'all, I had a question on mind. So i found a home, its listed above $400,000 Duplex in the Sunny side Place area, if you are from houston you know gentrification is happening around this are. The home has been on market for a few months, almost a year. I want to offer in the ball park of $370,00o to test waters have them meet me in the middle around 390,000 with a fixed rate 30 year 6.75%. The Mortgage would be around $3587/ month including insurance, taxes, Mortage insurance. Its a 2 unit , 3 bed 2 bath build in both units. 

I am a bit worried about the investment as it is my first property any advice?
