Am I being unrealistic here in my expectations?

We work with insurance companies and help homeowners with damage to their properties by educating them about (and advocating their position all the way through) the claims process and allowing them to understand their options when their homes are damaged by storms or some other cause.  

Mentor claimed 50% of my new tenants security deposit as profit to himself for explaining to me how to rent a property.

Hi, Everyone,I am a novice real estate investor in Florida and in my city, there is one team of agents who claims that they are number 1 top selling agent in the local market and they said there has been about 160 sales for the past year.

(Remember there is a 2 year homestead period for TX and the borrower can come back within that period to claim his property).

There is something fundamentally wrong somewhere in your approach OR your expectations/criteria are unrealistic.

The other one that fell through had a judgement filed against the homeowner right after we did the quit claim with the mortgagor and were about to close and redeem the property from the person that bought it at the sheriff sale.That judgement terminated the mortgagor's (and therefore our) ability to redeem that property.The response rate on our marketing campaigns has been extremely low; south of 1%, in fact.Our campaigns include door knocking, leaving notes on doors, as well as mailing the property and new addresses of the owners (when applicable).  

That's all I was asking, I'll have him quick claim deed the property to me.

I don't have calculated statistical data to back this claim up, and it could be regional, but it often seems that appraisers are more generous when it comes to appraised market rents than they are when it comes to value.I'll not bore you with the math, but the arithmetic is more generous if you do not intend to live in the property than if you do intend to live in the property (If you aren't going to live there, it is in theory possible to have a calculated DTI of 0.000%... which is in part why commercial financing uses DSCR not DTI). 

Like others said 70% rule is just a guideline which help you weed out unrealistic deals quickly, if you look at so many deals per day this help you save time on deal analysis and let you do other stuffs.
