I've identified a few apartments, but would like to some additional insight on the appraisal process from other investors who have implemented this method.The big question I have is how do banks appraise a newly rehabbed 2-4 flat? 

This should help you identify who is legit and who is inexperienced or shady. 

It really comes down more so to your carrying costs to establish the metrics you'll need to identify your Cap rate, ROI/ROE.

Anything I should ask the selling agent prior to touring the place to identify any causes for concern before wasting their time touring the place?

Identify all expenses.

 ( This is where I always say team up with an agent that will help you identify the money making properties vs the money pit ones!)

I am worried that in a seller's market like now, everything is selling so fast, will we be able to make the timeline to identify 3 properties within 45 days?
