Once you have an idea of 3-4 cities I would go bananas on BP getting convos established with individuals you'd need in each area to get a better feel for the area and if you can establish the appropriate human infrastructure to make this work. 

They can guide you on what finish levels are appropriate, and set you up with a good contacts (title company, etc).However, I partially disagree with you about running "real numbers" . 

I've confirmed the land is zoned appropriately to do this, but just need to find some data on construction/development costs so I can run the numbers to see if they work for my goals.

Question- If they say they are renewing, how is this formalized,Do you suggest preparing a whole new lease with the new dates, etc, or is an addendum to the old lease more appropriate which states the new beginning and end dates are for 1 year, and not month - month. 

I do this part time and am looking for a brokerage that is appropriate for me. 

I imagine balancing the flip + 1031 + acquiring this new property and managing finances through the appropriate order of operations would be an order of magnitude more difficult than a standard purchase.

You rent out the property to achieve appropriate positive cashflow after covering all your costs and depending on the type of property, investment, lender...etc you refi to get roughly 75% LTV of the new appraised value. 

First of all I would select a niche that is appropriate for your goals.
