Rehab expenses on a BRRRR so high you can’t get right appraisal

[Mike Schorah]

How unlikely is it to have rehab expenses on a BRRRR so high that you can't get the appraisal needed?

I always hear about people who are BRRRRing complain about low appraisals. I never hear about people complaining about rehab costs being too high. Does this mean that a high appraisal solves everything if a rehab somehow gets out of control?
