That means you can't wholesale a contract that is not assignable without specific consent by your seller to allow just anyone off the street to step into your shoes and perform your obligation to pay.  

Let me offer my own, biased reason: The status quo is too entrenched right now and protecting their interests, as I would myself if I'm in their shoes.

If I was on a shoe string budget I would drive and try and locate houses you can mail to or knock on their door.  

Put yourself in the shoes of the prospect you're mailing to.  

Put your self in my shoes please I have not done this in my life and I'm a little scared about signing contracts.

I was in your shoes once upon a time, and know how much work it is!

RealFloors in Greenville, SC and pay $10.75/yard installed + $1.25/foot for shoe molding.  

In your shoes, I would do a vacation rental.

If I were in your shoes, I wouldn't worry about trying to explain it.

But one thing's for sure when you start getting financial investment advice from your hair dresser and shoe shine man it's time to put your money into cash and sit on the sidelines.
