Even within a state, the experience can vary dramatically. 

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

Of course your individual experience may vary and maybe you have a marketing and sales background so it is a good fit.

Even from contractors on a project you can get quotes that vary by 50% or more. 

IMO there are two neighborhoods in Franklinton and your return can vary depending on which one you are in.  

Do you use a varied investment approach or just one type?

I understand that these rules vary depending on the state, but any thoughts on this?

The rates vary throughout the State because of the different millage rates and tax districts, but in Richland County for instance, the taxes essentially triple once it goes from legal resident to non legal residence. 

In Central Jersey where the majority of our sales activity is, the towns vary widely in enforcement of this. 

When you move away from investment in SFR, into commercial and investment type real estate, you get a much more varied valuation over time.
