I am buying my first home right now, and this VERY thing just arose in my world. The banks attorney requested a certified survey days before my interest lock was due to expire.
I paid $800 to have a survey rushed, the attorney has had it for 2 days now, and I have not yet gotten a closing date. I will not need an interest lock extension.
So for me- more than 2 days and counting. I will give you the actual number of days as soon as I get a response.
