If you already have the fault line mapped with a fault trench study, then that is one big variable out of the way.

The reason you are seeing a wide range per foot of sale price is because there are hundreds of variables in NNN properties.

Because there are only two variables to worry about, you can focus your attack.

(this description excludes other variables such as inflation, mortgage rate drift, etc

No DTIs... might be a good option if you are concerned about this variable 

I recommend you do this annually to adjust for utility increases and other variables.

@Vernon Huffman, the answer to these scenarios is that it always depends on many other factors/variables.

CAP Rates can be a beautiful thing, they allow an investor to get a quick comparison of properties without digging too deep into the deal.When using CAP rates on MHPs I want to give a few warnings because there are additional variables to consider.

The increase in interest rates follows a similar pattern as the one seen between 2004-07, however I believe that there is one major difference that makes today's market less likely to see a similar surge in delinquencies: a lower % of variable rate mortgages (Figure 2).

No doubt you won't be able to beat the 4.75%, but if that is variable or short fixed term there may be ways to better your cash-flow position.
