With rising interest rates, I've heard push back that cap rates don't make sense and deals aren't "good", especially if there isn't a big value add opportunity.

Is this because conventional/investment property loans aren’t normally used for flips?

It doesn't have anything to do with what else you own, assuming those rental properties are not FHA and it sounds like they aren't. 

If they aren't out by the 26th I would imagine I have to schedule a time to get the sheriff and that's going to take another 2-3 weeks. 

And you're also correct that most experienced investors aren't surprised by that behavior.

No, you aren't "vetting" them.

@Cleon Wilson It's always good experience until you don't have time to constantly go back and forth to certain sellers' properties that aren't as motivated.
