However, many sellers will not accept an offer subject to an appraisal. 

Point being that property you acquire 1-2 years ago is likely to be subject to deferred maintenance and capex, so their "long term" performance in rankings 1), 3) might skew poorly in year 1-2 but may pickup  after you've found and fixed all the hidden issues.I know if i did this exercise across my portfolio, the recently acquired ones wouldn't be fairly "stacked" because of all the year 1-2 cost build up from what the seller deferred, but have good chances at being future performers in years 3-5.Maybe that's why you have 2) and 5) but curious your general thoughts here are for evaluating this. 

The first thing I'd recommend is focus on a market where you either 1) currently or have previously lived, 2) have family/friends that live there, or 3) travel to/vacation there frequently.

I listen to RE podcast pretty frequently and Marco's was one of them I used to listen to up until a few months ago.

Arthur - As I mentioned to another poster above, please call the SEC and give them all the details about your interactions with RADD, about company insiders looting their investment capital in the bright light of day through the use of multi million dollar promissory notes between the Mendenhall family and the company, that they've been paying their sales force in Ontario and Pennsylvania via 1099 and that a review of the real estate assets in Philadelphia newspaper and Texas that is subject to foreclosure litigation does not match up to what they should have been purchasing based upon what is described in their sales presentations.  

Being a subject matter expert and having a clear strategy is far more important than picking a market.

Computers can analyze property based on subjective data (square footage, # of beds/baths, etc.) but cannot calculate for objective data (quality of kitchen cabinets/counters, size of bedrooms and bathrooms, view out the living room window, etc.).You should study the market yourself.

I agree with @Connor Hibbs's comment on terms for first time flippers and if this is something you want to start doing more frequently I'd look for lenders that offer some type of rewards program to gain better terms through doing repeat business.
