I am just now coming out Marcus & Millichap's training program and have been assigned to specialize in brokering apartment buildings in northern Colorado.

You could use the standard inspection addendum even if you have a different PSA, but title co's are more familiar with the boilerplate realtors use obviously.I use the standard one here in WA and just cross out and initial 'not' in the Not Assignable clause.  

I thought it was a bad idea then, since i had to pay 33% on my monthly income (as a full time employee in a trading co.) which i used to enjoy spending in outings and activities.

I wonder if the Texas Turnkey co will divulge this obvious risk down the line? 

Looking for a $700K residential 15-30 year loan. I'm self employed and can put down 20-30%. Not looking for headaches from the normal bank loans which I probably can't get anyway. Lost many investment properties in 20...

I don't have all the answers you need, but I would say to make sure the title work is properly done, either BY a title co. or following direct steps laid out by a reputable title co.... even some lawyers screw this up.I've had to shop a property closing around to 10 different title companies before I was lucky enough to find one to close it for me...all this because the family members used a lawyer to transfer title between each other. 

I'm originally from there, but living in CO now.  

That is I buy into portfolios of 10 SFR at a time that are co-owned by the managers for aligned interest.

I am just getting started and need to build a network of investors, title co's, and RE agents, just to name a few.
