It seems like the classes are determined by community opinion.So, is there like some guide chart to know what type of fico score to expect for each class? 

I made a chart below to try and make some sense of this.

I was in the County office yesterday, and noted a chart predicting a 15,000 unit shortfall in homes in 2030. 

AllenIt's put out by NASB which is involved in lending to Solo 401ks and Checkbook IRA (or IRA LLCs).It's cheapest on their site.It has great charts and tables showing UBIT and UBTI as it relates to an IRA.I've used them for non-recourse loans and I have both 20 year and a 5 year arm depending on the numbers that worked. 

normally your county does a annual chart.  

The price seems like a great deal because in the last 10 years the lowest price on the zillow chart is about $99,000 which was in the housing market bust of 2007-2008. 

IE full blow rehabs.what I liked about vickburg compared to say Jackson or Memphis or other southern markets at those price points.. there is no real crime and you don't get your stuff stolen.I had a good experience there and the history is off the charts for those that may be civil war buffs

I didn't realize it would be illegal (or morally questionable) to do this, which is precisely why I raised the question here before acting.

It has charts and detailed statistics on house appreciation for 380 city/metro areas in all 50 states going back 30 years.  

Looking a the chart in the article, the issue may be more that incomes have stagnated rather than rents have climbed.
