I average $500/unit in cash flow (each 4 unit building gives me between $2000-3000/month in cash flow after paying mortgage, taxes, insurance, maintenance, utilities, cap-ex reserve).

Here is a blog where I wrote about a recent 42 unit we bought and did creative things to add value. https://www.biggerpockets.com/renewsblog/bought-multi-million-dollar-apartment-complex-age-26/Just a few ways to produce ancillary income:- Laundry Coin laundryDetergent/laundry essentials in a vending machine in the common area laundry rooms.Rent individual W/D to each unit-Parking Garage parkingCovered parkingprime spot parkingJust plain old charge for parking-Renovations Interior units upgradesCommon area renovationExterior upgrades for curb appeal-Vending machines In common areas such as exercise room, pool house, laundry or leasing office-Trash pick up service In high-end buildings they have a service where you can set trash outside your door and for a fee maintenance will go around each night and collect it so the resident doesn't have to carry it to the dumpster.

It's a traditionally very low income neighborhood.

I spent a great portion of my life in school and as such lost out on a lot of financial/investment opportunities since I was in school or in low paying jobs in order to gain experience.  

I wouldn't use a number that low for a 3/2 house much less a 10 unit building.How about 3k-6k per door as an estimate then adjust from there after more due diligence.

Read my posts in this thread from minutes ago:https://www.biggerpockets.com/forums/83/topics/235...As to that deal, you won't have an option, you'll have a sale contract, the seller named his poison by putting requirements for maintenance in an option contract.

From the initial assessment of this property the property expenses are out of balance (i.e. no property management figured, maintenance cost is $500/year, fuel costs of over $4000, along with some other similar items) not to mention some deferred maintenance on the property as well.

I am in Palm Harbor and I use a maintenance company   for ongoing maintenance, and they do roofs, all rehab projects, I have been with them since 2013 when we did a full rehab in Dunedin. 

I would think you would only do calculations based on what you plan to do to the house, but I am curious what others thinkI haven't had to worry about this yet, because my properties thus far are relatively low end homes.

Great insight as I'm licensed and deal with low priced homes with high cash flow.
