BP provides a wealth of information, but also an invaluable social connection.  

This value is almost always initially equal to the starting amount of the contract, can increase in value - often has what’s known as a “guaranteed step-up” or “roll-up,” and is a figure upon which income streams are based on in retirement.  

For every dollar you either add in value to your building (increase in rent, etc) and for every dollar you're able to save in cost (heating, insurance, etc), your lending institution should be willing to lend you through refinancing between 10 and 20 times the value you added.

I would start with data the municipality will give you. 

It's how I have found deals, I just talk to everyone and always keep my eyes open from as many data sources as as I can.   

@Jonathan Pacilio before last year these properties didn’t exist so you may not find a ton of data.

There many mistakes an investor can make to lose money.The 2nd is a economic contraction causing a lose in value such that the investor cannot continue to hold the asset through the contraction.If your goal is to simply limit risk I would go with passively investing in a syndication.

Your number and other data of you are public information.

Using the 100k purchase price in the above example, if you can reasonably assign $30k in value to the land, you'll need to make at least $70k in capital improvements to the structure. 

I am a buy and hold investor primarily, so if a property is cash flowing, who cares if it drops in value by 10, 20, 30% in the short term?
