we eventually refied after only 9 months with a significant noi increase through fannie becoming cash on cash plus a sizeable non taxable event along with 5 years i/o at a very low rate which allows for a healthy cash flow

Rates are lower and the products available (30 year I/O, 40 YR AM, ARM) are usually more diverse.

Generally, the rate might be higher on DSCR Multifamily but counteracted with a superior 30-year fixed rate (fully amortizing or even IO for 10 years) which can actually have a bigger effect on monthly payment and takes away any balloon or floating rate risk.https://www.biggerpockets.com/blog/multifamily-dscr-loans

I’ve been given quotes for everything from 5 year ARMs, 5 year ARM IO, to 7 to 10 years of both of those on up to 30 year fixed.

Multi-Family, IOS, house flipping and later on property development.

@Josh MacThese usually float with the prime rate so factor that in too, it's 8.5% currently but many offer IO for repayment which can be attractive for some.   

There are times that I/O can be beneficial to all parties but with mt particular case, the units are turnkey, renting at market value so there is no need for me not to attack principle.If you're a seller, I/O is the way to go but as a buyer, I never want to get into any I/O for more than 1 year, tops.What are your thoughts?

I was able to get it at 7.5% I/O with 20% down and now prepay.

And if fixed I/O, what happens to cash flow if/when loan goes to amortizing?  

Can you try to utilize a 40yr term or I/O period to lower the payments a few bucks?
