Also, I believe $900 is a “safe” rental price for the area D/FW unless in a bad neighborhood, a good area could command $100+ more each door.  

The deal requires at least $200K to close plus $100K to rehab but will command rents upwards of $4200/month with non-renovated comps selling at $350K.

FYI, a 5 bedroom home command about $2375 a month.

You serve at the whims of our Commander in Chief and what you think may happen just might not.  

For the average flipper this deal probably wouldn't command a high enough profit margin to justify the work involved, but if your goal is to buy-and-hold, this could be a real winner.

The rents are below market, the current owner does not charge any rent for outside parking spaces, the parking garage rents are below market rate, there is a beautiful unit being used as an office that could command $900/month, storage fees are not implemented, water is being paid by owner, etc.

I say this to help you get a larger return in the future and help command larger rent sums.

Is it worth it to spend time retiling this bathroom my self or is it fine and won't command much more in rent?

Units are in good condition, but could use some updating which could in turn command higher rent rates.  

If the market is at $1000 per month and your property is comparable with houses commanding that rent, then you should raise rent immediately.
