To add additional thoughts, I feel that the "rehab estimates is subjective" comment is a poor excuse for a justification.

What they are looking for is promise-breakers, IE once in a while someone calls me to buy their third "primary residence" in a year, always with some "excuse" like "the neighbors smell when they cook" for why they - yet again - can't fulfill their 1 year promise.

Please excuse my inexperience.
