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, every owner's situation is unique and factors like the legal entity involved, purchase date, adequate passive income that can be offset with the cost segregation study, etc., will need to be considered.

Be sure to factor in repair costs to keep things profitable.

Recently, a lot of the market factors that kept people away, are the same that are drawing attention.

But that is calculated after expenses and depreciation is factored in. 

I'm sure there's other stuff you'll want to factor in - what businesses are moving to and from each areas. 

Insurance is now a big factor in the expenses of investment properties, even here in Reno, NV there are areas that have had large increases for single and multifamily properties.

A lot of factors go into this. 

That depends on a lot of personal factors such as your finances.

Not only for the census ending in 2020 but also the projected population from 2020 to 2025.I agree that population increase is important and should be factored in when analyzing a property.
