Denise,
Those numbers look good to me. Like people said, it's not a bad deal, but not great.
Why did you choose to use cap rate instead of cash on cash return? Interestingly enough your CoC is 6.3% (1624/25700).
I thought I saw you mention that the property only needed paint, but I couldn't find that on second glance. Are there any repairs or make ready required?
You budgeted $1400 for repairs and maintenance, but that could easily get exceeded if you need to do a make ready a year from purchase or if a major expense comes up (water heater, roof, AC). Is everything else fairly new? If so, then I would say that's a fair estimate.
Final note, you could probably bump up your CoC by lowering mgmt costs. I used to have a mgmt co at $120/month and for the lackluster service I was getting, I was paying too much. You're estimating at $116 a month.
Speak with @Jerry Ta about property management if you choose not to self manage.
But make the offer if you're comfortable with it! You gotta start somewhere.
Oh and 2% exists in Houston, you just gotta go to the low income areas.
