There are many factors, as with any real estate market:(1) Location. 

The biggest factors, from what I can tell, are age and rebuild cost. 

Of course you have to factor in realtor and closing costs on top.

I developed friendships and met a lot of great people at Rod's event and value his input and what he's doing for MFH community. 

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).

You have to factor in demand and vacancy rates to determine if it will be more profitable, and that’s specific for each market.

(I know everyone doesn't have that opportunity.)Another factor is the type of deals you're looking for.

It explains the team that you should develop to have a strong foundation under you while investing remotely.https://www.biggerpockets.com/blog/core-four-real-estate-team
