From those numbers, 3 of us and my girlfriend will be living in the house, so say 1800/4 + utilities estimate, we would come out to around 500/month each if we split the costs evenly.

So, apart from estimating your price by checking similar properties in the area, make sure that you also factor in all of your expenses such as appliances, utilities and taxes when figuring out how much rent to charge.

I'm not looking to sell but rent and from doing research I should be able to get 1100-1300 and renters pay their own utilities and water/sewage.

I have found that property taxes and utilities can have a large impact on how well a market cashflows and that is why price to rent ratio isnt a perfect metric.

You are also the one that has to cover the utilities included wifi and lawn maintenance.

Dear Colleagues,I need help with a spreadsheet or some calculator for distributing utility bills among tenants in my 8 unit building This is an old victorian multifam and there is just no way to sub meter these units.Any help in this regard is greatly appreciated.

Utilities are not fixed costs. 

@Eric SmithYou should be able to utilize direct to owner mailing for this size of properties you are targeting.

In regards how much cash flow you can expect, there are a few variables that will drive the result and a few of them would be 1) purchase price 2) monthly rents 3) monthly expenses (i.e. taxes, insurance, utilities, etc).

To perform a lot split on an existing lot with an already built home, the new bill allows requirements from individual municipalities to set minimum lot SF and layouts, there are utility easement issues, and most existing homeowners will not want to split their SF lot on their primary residence.
