@Paul Hamilton, at first glance, I’m not seeing 4% on MF. I’m been told by some lenders local and regional that 5+ units is 5.5-6%. As for utilities, yes, most (all the ones I’ve seen) duplexes have separate utilities (especially electricity), but in a monster house situation or cottages on one property may have on water / sewer bill and use trash receptacle (garbage). I still would ask from the owner their P&L or operating statement to see what they are paying. As for capex, this depends on whether they have rehabbed/ replaced key systems/ items recently. I generally assume that the older the house the higher the capex. 10% seems reasonable for newer homes or ones recently (fully) rehabbed, but not older homes not rehabbed. In this case, I would increase it. Also costs for maintenance will be higher on older homes. Don’t forget vacancy rates and the associated turn over costs. I’m running an average of $1200 for those. So if you’re only making $100 a door and you have an average tenant there for only 12-15 months, you can make very little to no CF.
