Now North Oak Park (Med Center) is very desirable. 

There are lots of different neighborhoods within relatively short distance to the med center.

But our particular focus is near the Med Center area, for the reason of Job Growth and almost recession proof economy centered around Aging populations needing more health care.Houston is adding 30,000+ jobs to the Med Center over the next 3 years so any type of investing ahead of that job growth is expected to be positive in the longer term.Do you invest in Houston?

I deal mostly in the Med Center.

I made my offer at $147k (So I can at least snag $150 a door and maybe $200 down the road, but that's speculative) because at $175k (list price) there's no profit, I would say it's a loss if you add the time involved in organizing the deal, and $180k, you're cheating yourself.Your monthly maintenance is too low, I would at least say $100 bucks a month, if you include cap ex make that $170 a month.There's no profit in the deal, the square footage of the house sucks, you have no backyard, no garage, you're going to need to build a car port, you're within kissing distance of another duplex so you have no privacy, and it doesn't matter how close it is to the med center, your rents will stay low due to the fact that the property is missing the aforementioned features. 

If you have market where you get a lot of fly in workers who aren't traveling with their own vehicle and your property happens to be located within walking or public transit distance to the med center you'll get travelers who don't bring their own vehicles.

Are any of your STRs in the NW quadrant by the med center?

you are really close to the med center.

I have a lot in Brookhaven (close to the Med Center) that I want to build 5 houses in.

Pearland is great due to its proximity to the med center.
