Covering difference on short appraisal?

[James Mcsweeney]

Currently in contract with a duplex, good condition. 2/1 each side. But appraisal is coming in short over 15k. With the difference, i'm looking at roughly 8% CoC return. I can get better deals, but I do like the area. Are other investors experiencing same thing? Given the competition, are you experiencing appraisals coming in short and just covering difference or walking on it?
