Deal analysis help please!

[Luis Saenz]

hi BP, I need an experienced investor's help. I have a deal I'm trying to close, but I'm a newbie and I have a few questions about the deal and need help analysing it. 

It's is going to be an assumption. 

Arv 180k

Loan payoff 147k

Repairs 15k

Loan duration 10/2037

Interest 4.125

Reinstatement is 10k

Monthly payments 1400

My Questions

Where can I get an abstract of title?

In the contract, who do I write as the main buyer? Or do is just wait until I find the buyer to fill in that part?

What is a good assignment fee for this deal?

Thanks for any feedback!
