Multi-Family in Framingham, MA

[Sage Jankowitz]

Here are the stats, I'm trying to decide if it's worth putting a lowball offer on the table. I would wholesale this property to an investor of mine who is looking for multis in the area:

Gross Rents: $2750/Month
Operating Expenses: $1375/Month
NOI: $1375/Month
They're asking for $215K, I would offer $125K:
Mortgage Payment: ($125K, 30 yrs, 7%) = $832
Cash Flow: $543 per a month

Are these calculations correct? Cash flow seems wayyyy too high...
