Does Texas allow loan assumption without triggering a due on sale clause?

I make a couple of assumptions from this paragraph:1.

That is the law of supply and demand HOWEVER prices are not decreasing, so you have to go back up and question your assumptions about population decrease and the desirabilty and demand for living in Chicago.

That's a BIG difference to your number crunching, so you'd BETTER not start out with wrong assumptions!

I realize there are a bunch of REIA’s out there, but I didn’t know if there were any that would be more ideal for the person just starting out but specifically by way of wholesaling.I feel like I should disclose the fact that I’m not posting this question under the assumption that just showing up means my work is done and I will immediately be successful haha. 

"If you were young again"...That's an incorrect assumption that people who start out in REI are young. 

Don't make the lethal assumption that you need to use the same PM for all of the properties.

These are my opinions and assumptions.

Of course my fairly uneducated assumption is that if we were indeed finding ourselves in that awful scenario, the housing market along with the rest of our economy would be negatively impacted. 

Even with assumptions (not a fan) of buying at a lower price and raising rents by $100 or $150 to market, the 50% rule still yields break even or very minimal cash flow.
