The $7630 in expenses is Garbage, electric, water/sewer, lawn care, insurance, real estate taxes, cleaning of hallways, and po box rental. 

Who does the lawn mowing?

I decided to go slightly higher as I haven't included the cost of hiring a lawn/snow service.2.

Underbrush was removed and the lawn was cut.  

Maybe you can hire one of them for lawn care or slide him $20 for keeping an eye open for you.

So a 2 BR 2 BATH would pay twice the water usage of a 2 BR 1 BATH.You also need to take into account the common usages, like washing machines, car washes, lawn sprinklers.I would just pick a method that seems most fair and work out the flat fee from that.Curious, is there any advantage to charge a flat water fee of $25 instead of just increasing the rent by $25 and say water is included?

Ours is about 50 feet from the street and would only be going through lawn.

Kyle, place in some numbers of a house you were looking at, price, mortgage,taxes etc. average rent for the area for same size units. may be a little easier to get answers from people if they can help check your figures. i know in the area that i am investing right now, a 4 bedroom unit runs me $200 / bedroom/ month to run and i have a 2 family with 8 bedrooms that runs me $150- the more bedrooms the less per bedroom. that is without the mortgage. that can fluctuate depending on the cost of the property and the amount you put down, so i leave that number separate. to me Maintenance seems a little high, if you have a unit that collects $1700 per month ( 20,400 yr ) at 15% that's $3060 for lawn care and snow removal. i pay half that $1500 - so that's 7 1/2 percent ( these numbers come from my 4 bedroom unit ( 1700 & 1500 )). that would be another 1500 in your pocket. what you can do is ask a management co. in the area what is the typical charge for maintenance, or a local landscaper. that 1500 could make a difference in your numbers, and there may be others. show a sample and you may get some insight from others

But remember you have 5 different roofs, 5 different properties, 5 lawns to maintain, etc.Good luck!

I have a tenant that lives in one of my units that did some lawn care work for me, which went fine.
