Help w/forecasting costs? - College Station Townhome Investment

[Account Closed]

Hello, I am in the process of creating an excel model that will determine if a 4bd/5ba townhome investment will be profitable. I have never purchased a property before, and am trying to forecast expenses. 

What type of landlord/property insurance coverage will a FHA lender typically require? Which insurance company is the cheapest? Which has the best value?

How much do you think I will spend in yearly repairs on the property on small things such as garbage disposal repair, fridge/oven/microwave, etc. (Excluding larger expenses carpet cleaning, repainting, roof replacement).

What would be the estimated gas/electric/water/sewer monthly charges? Assuming I do not pass these costs along to the tenant? 

Any advice/recommendations are welcomed! If any of you use your own model or website when analyzing a deal and do not mind sharing, please do. Thanks.
