Thank you everyone for replying to this, all of you have good info to reflect on.
To answer everyone at once, I have put in water/ sewer, Garbage, Electric, Vacancy @5%, Maitenance @5%, Capex @10% and management @10%. Im managing this myself.
Ive included all of my expenses so I believe. The building was built in the 60s and in great shape. There is about $20k In repairs, I'm factoring it at $25k with a purchase price of $55k. I see other buildings in the area going for $75k and back in 2007 this property sold for $120k, but thats not todays market. The down payment is $11k, I have others putting in $5k and myself $6k to get this deal. So with the $20K in repairs, that would be fixing all major problems with building, Including 2 new furnaces, 2 Hot water heaters, 2 bathroom remodels, and new flooring in 1 unit. I see it as this would bring down the maintenance and capex costs, leaving me with the cashflow that I need next year when I can tweek the numbers to real maintenance costs. Since i'm unexperienced i'm putting in larger numbers to save, for those "oh ****" moments. its a foreclosure and that last owner remodeled 1 unit completely and looks very nice.
This will not be owner occupied.
