(List source is widely known, affordable and predictable)People who have loans coming due? 

I think it's pretty common to airbnb in this area but I like the idea of stable predictable cashflow. 

In terms of predicting the future, I don't think there is a site out there yet that does that ;) Read the news, local journals and newspapers, and you'll get a better idea for where each area is heading.  

Moving forward we are paying off debt and trying to maintain a 10%+ liquidity.We can't predict a recession however, we can control what we have.

@Scott MacI appreciate the calculated prediction.

You are saying I should read the tenants mind and predict if they will stay 1 year or 10 years.

Major growth predicted in the Phoenix SF market. 

No one can predict the future and that far ahead and this is where you have to weigh your risk tolerance and whether you prefer to keep as much of your money or give it to the bank, by securing a vanilla 30, 25, 20, 15, 10 year loan.

If we start with a cash flowing investment, add predictable value to it, use a conservative exit assumption, and show sensitivities around that assumption, we have a predictable range.

Once you build a model you like that uses sources you trust and appears to align with reality maintaining it is simple.Also, if it really does match the observed reality (or comes close) you can use it to predict, at least generally, enough to include the data at some weight in your decisions, which van increase your confidence.And i promise this is the last word from me - historical (even 2 months ago) data is pretty available since few care after the sale what it sold for.
