We have an extremely strong economy surrounded with good colleges and healthy public schools.

I want the ability to be financially healthy with no worries and to leave a legacy for my children and future generations.  

Our best rate is 10% with 2 points, and that goes to folks who have experience, liquidity, decent credit, and a project with a healthy margin.

The tenant simply wouldn't pay them, so I have two options: Fail the inspection and have the house drop out of the program, or pay and continue to collect healthy checks.

Start out strong building that healthy reputation and it will follow you throughout your life. 

Compare the two and look at the similarities or differences.Is there a healthy mixture of majority and minority people living in the area?

This total is about 25%, so your 10% security margin seems low.At 5% down you would want a fairly healthy reserve fund for unexpected high cost maintenance or vacancies as you have very little equity available.As it is, you're catching a falling knife in Grand Prairie and it is certainly conceivable that property prices and rents could fall a further 5%+ over the next 12 months, putting you in negative equity and cash flow territory. 

If one looks at underpinnings, "as a whole" the US market should keep modestly expanding over the next several decades - we have a healthy birth rate, good influx of immigration, diversity of household, and plenty of land to build and rehabilitate.

I would plan on putting $400 away a month for cap ex and repairs to start, but it's pretty newly renovated so I expect that will build to a healthy cushion early and I could back off the repair budget (still doing a few hundred for cap ex) after 6 months.

@Gabe Gordon, looks like a healthy cash flowing property!
