I wouldn't automatically assume DSCR rates will be significantly higher than traditional financing - that's not always the case.

@Denise CarringerMy preference is to go local - some community banks offer this type of service or local escrow companies, which is what I found, because they offer a higher level of service than most national.

We knew there was some hot air in them, I expected more fraudulent folks to have created note "funds" and it pyramid down and blow up but i think a lot got stopped in their tracks when they were anticipating a rate cut and not a lot of higher % debt notes to be offered so they never indulged in such tomfoolery.

Property taxes are 2% instead of 1% for landlords as a general rule (some districts may  be slightly higher). 

Mortgage lenders will qualify you for a higher purchase amount for multis than they would on a single, because they will count the rent you will be making on the other units as additional qualifying income for your loan application.

Traditional IRA withdrawals are taxed as ordinary income, with a 10% penalty if under 59½, potentially pushing you into a higher tax bracket.

Being a NYC resident (originally from Long Island), the price of entry in the area is on the higher end, so I've been considering some options in the NY Capitol region, as well as NJ and CT. 

The higher your equity gets on a single property, the more you are losing money. 

Lower rents, potentially higher vacancy rates, but also opportunities for value-add renovations.

It could go higher with additional work to the house.
