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. 

If the liability is in the name of the entity and/or the the property is free and clear and/or the cash flow is positive, then we analyze the income using the appropriate methodology for the business entity... but I'm already deep in the weeds and some new COVID rules for self-employed folks have just thickened that plot a bit... so I'll stop while i'm behind. :)Oh and for jumbo or portfolio loans, the worst-case average of 2 year of Schedule E income is likely what will go into the DTI (24 month average if income is trending up between the two years, 12 months if the more recent year had lower income). 

A modular home is a building methodology, it's not a home classification unlike Mobile/manufactured or HUD housing.

Your on the right path, many struggle with getting the hub & spoke methodology. 

Overall, are the rankings useful in identifying a market and does the methodology make sense for a real estate investor? 

I suspect the methodology used is taking the total number of federal jobs and dividing that by DCs population, which does not give quite an accurate picture as part of DCs population works in the suburbs, and the majority of those federal jobs located in DC are filled by suburbanites, which is where the majority of people actually live because DC proper is incredibly small. 

One of the posters provided his methodology for investing out of state and it makes a lot of sense but you can see that there is time and work involved

I'm trying to find the standard methodology used by appraisers in Florida- I understand that techniques can vary somewhat across regions.Does anyone have any good blogs or resources for understanding how Florida appraisers do what they do in a little more detail?
