Contingencies to pull out of offer

[Paul Papamarkos]

Hello BP,

This may be a rookie question however I am estimating after repair values on several listings and I was wondering if after I make an offer prior to viewing the property will I be able to pull out of the deal if After viewing the property I realize that the rehab cost is higher than I had originally estimated.

I would like to be able to make offers prior to viewing property but not be stuck if my estimates are off. Any way of writing in this type of contingency that allows me to pull out?

Thank you
