A binder title insurance policy

[D.Y. Lee]

I buy lots with cash and build houses with construction loan. I pay for owner's title policy when purchasing a lot and pay for lender's title policy when getting a construction loan. When getting a construction loan, sometimes I pay for a full lender's title policy which costs a lot more and sometimes I pay for a binder policy which is a lot less. Does anybody know why it is not consistent, who decides on either a full lender's policy or a binder policy, and how I can make sure to get a binder policy going forward? Thanks in advance!
