4 family worth it with 1 boiler and tenant thermostats in each unit?

[Joe Kato]

Have two 3-families with all separate utilities. NOI was $12000 per year per property before $7K mortgage interest.. Ready to sign a purchase agreement on a 4 family. agreed on price, selling for $150 less then at 2006 peak market. think I can get $12000 with heat as is budgeting $5k oil bill for heat.. Any thoughts about if this is a money maker or money pit? Brought a realtor in and she said she can rent heated apartments all day long no problem, but since there are 4 gas lines in the property for 4 separate domestic hot water heaters, was thinking to switch ti individual boilers for each unit.. Hope this 4 family doesn't consume all my time for the 15% ROI I am conservatively estimating..
