Your defense that there's a shortage of Dr's is fair.

We tried to note that we needed more communications from them, but response emails to us were always very defensive in tone.

I'll be visiting Dallas between the 8th and 15th of November, with my schedule tied up at a conference through the 12th, but eager to meet up thereafter.Could anyone share insights on the best areas in Dallas for short-term rentals which are also good potentials for appreciation?

If you go into a situation pointing fingers, you will make others become defensive and accomplish nothing. 

Few people do that for vacant land.The fact that a tax sale is void is what is called an affirmative defense.

So curious to see who else has gone through those 3 day workshops in hotel conference rooms and try to sell you more and more things.

I get that a person may not like hearing that cold dose of reality, I hear it often of those at MNREIA who say "please check out this deal" with giant grins only to turn sour and defensive when I inform them their 189K acquisition with a cap of 4.15% and negative cash flow after properly appropriating funds it's toxic waste and I would rather have a bank bond than that bomb ticking away in my portfolio.

I am just commenting on what activity requires a real estate license and assigning contracts is selling RE without a license at least according to the investigator I had lunch with.. and some of these folks that get turned in are going to learn the hard way.. they can listen to all the equitable interest mumbo jumbo but those people spouting that are not going to pay their legal defense fees and civil penalties..I know 3 that have been nailed in the last 5 to 7 years they bring me their deals so we CLOSE on them before we market them.. all legal and all profitable or at least we hope right ?

One MUST have 3 lines of defense, it's a must. 

Plus ending the conference with them renting out Islands of Adventure?!
