Anyway, quick look indicates it follows the Federal methodology. 

City has an inconsistent methodology on assessing taxes, for me I think they saw the purchase price (215,000) and just decided to increase.  

You just need to come up with a defensible methodology for the valuation you assign.

But, maybe its just my methodology of just finding a one or two good, solid deals.

Does anybody have experience using Networth Realty?  I stumbled across them looking to invest in the DFW metroplex. Intriguing website...  

Their methodology: Markets are considered more or less at risk based on the percentage of housing units receiving a foreclosure notice in Q4 2019, the percent of homes underwater (LTV 100 or greater) in Q4 2019, and the percentage of local wages required to pay for major home ownership expenses.

That's my methodology, there are many you will find on this site that can work.

The methodology used to gather the data can be unclear, and peoples' application of them is often, for lack of better words, garbage.

I'd like to know if seasons renters out there have a methodology around minimum profitability per property per month.  

That being said, be sure and center on one methodology and go all in.
