I would appreciate advice on how to evaluate this opportunity.

@Eric Siebert The use of  Zillow and other sites can help you evaluate market values and rent prices to get a general idea.

In any case - I would re-evaluate the ARV to make sure you have it correct and go base off of that.  

-After a good credibility and standing of our legal entity is built, get int BRRRR strategy to build passive cash flow-Get into commercial lease real estate, again BRRRR strategy as it is not only evaluated by comp method, but based on producing income, that will allow bigger profit after rehab and refinance.

Anyways, this isn't intended to open a big can on what metrics to use when evaluating income property.  

Each was a progression as we sold to move on so we weren't using existing properties as leverage.  

But I will see as we lease them up and re-evaluate.  

In any case I would, personally, not obtain a formal appraisal as my method for evaluating the deal.

“The best tool we use is Evernote to track progress.

If that $100-$200/door is just on the first day, but they are super high quality doors with a long history of appreciation in both rents and prices, then that is a totally different story and that would accelerate your progress and you will get there much faster than you may think.
