Same way you'd evaluate dividends on a stock. 

Imagine when you buy a property having no middleman but the parties can transact and you can watch as the closing progresses through the block chain.  

There is a HUGE trust factor you must consider - not only in getting an investor to work with you, but in their evaluation of your integrity and ability to perform. 

Use current numbers to evaluate the deal first.Why do you have 2 different Vacancy percentages in your Scenarios? 

I always get an email from Cozy letting me know that the payment is "in progress" (starting to transfer), and another when it is processed (transferred). 

What you sent me will definetly get used once I start evaluating deals.Thanks againPaul

When evaluating markets, I like to look at the average rents, average days on market, and average cost to purchase.

(IF they approve to replace it, due to past hail/wind storms)   But as Nathan said, be sure to get 2-3 opinions, from Roofers in your area that have LONGEVITY and are known to be Honest about pricing and evaluation (yes, there are still a few of us like that around!)

Another tool I believe is invaluable to how to compare markets/neighborhoods for evaluation to invest as a first time buyer.

It is a bit complicated to progress in our area due to the high prices.
