Also with only 2 tenants keeping track of the rent and collecting it is fairly simple. I have helped other clients with duplex properties and would be happy to talk with you some more about this market. I also have some great referrals for people that can help you with upkeep and so forth.

Also another way to save is to find a property that has better rents. I know places in slc that you can buy for 100k or less and rent it out for $1,000-1,100 a month. Let me know if you are interested.
