The buyer and seller draft the Land Contract, then signed the Land Contract with notary.   

Zillow will be accurate occasionally in a very homogenous area with very homogenous buyers.

If he feels like his buyer is shady in any way you will for sure not get the deal.

@Ayman Elmasik what you can do is bring one of your potential buyers by the property and have them look at it and make you an offer on the property.

Hello Bigger Pockets community,I have a question and perhaps others have the same question so I thought I'd post it and see what the wise folks here think.I accepted an offer on one of my properties and am giving the buyer a subsidy ("help with closing costs" as part of the deal).

Good to hear.Your buyer's lender may not require survey.

I have buyers who don't know what or where they are looking so I don't narrow my auto-search down for them other than the basics (2-4 units for example).

Buyers will ask for custom changes. 

And if assign, what happens if you cannot unlicensed broker and find a buyer?

They've gone as far as to deny entry to perspective buyers and hire an attorney.
