I mitigate the unknowns associated with the rehab in a couple of different ways:1.

I know right now with rates in the upper 6s and low 7s instead of 8 now, there's an alarming number of people trying to buy since there's unknowns of where they go from here.

The listing broker does volume but doesn't want unknown buyers or flakes to make them look bad to sellers and take up all of their time.

It was accepted.Here are the numbers:ARV $400,000 (probably a little more, I hope)Rehab $175,000 (probably a little less, I hope)Since there were some unknowns I had to make a conservative offer. 

There will be also demand for reserve crews that are on standby to go fly a trip and need a place to stay for an unknown period of time.

That was a big unknown for me and for sure one of the reasons why we slowed down .

I don't like unknown's. 

@Carlton B.I feel like every project we have done there is some issue we had not budgeted for so I try to just build in unknown percentages of 15 to 20%.  

The owner has passed, and the daughter has not opened probate, for unknown reasons, and she's not paying the property taxes.

I don't believe for a second that the occupants gave some unknown person $5K.
