Here is how I view the numbers:Mortgage Rate 5.00%Length of Mortgage in years 30Monthly Mortgage payment $1,503.10 Taxes $400.00 Sewer and Water $100.00 Trash $- Heat/Utilities $- HOA $- Cap Ex and Ops $175.00 Insurance $166.67 Mgmt Fee $370.00 Vacancy $296.00 Total Expenses $3,010.77 Unit 1 $2,200.00 Unit 2 $1,500.00Total Revenue $3,700.00 Cashflow/month $689.23Cash on Cash Return 11.18%

the cost of the appliances and the a/c and heat repairs should have already been added in the price of the rent.

Because I'm an idiot, I thought I would save some money by shutting the heat off in the other unit of my property (I live in Denver and it was bitterly cold this particular week).  

I also recommend you have them wash and dry anything cloth on a high heat setting.  

. $50 may not seem like much at first, but thats $600 at the end of the year, plus what I would save on utilities to heat and cool the extra space, which to me $600 is a nice kayak or all the money I need for christmas presents etc.So from the perspective of a previous renter I would suggest some or all  of the following.

@Ryan Haase To follow-on to @Steve Babiak, there are several models of front-load, high-efficiency washing machines on the market which have built-in, in-line water heaters, which may be able to provide sufficient heat if your source water temperature is not too cold.  

They may loan less than $50k and I'd run the numbers with charging yourself rent to see if it makes sense. there is alot to consider who pays water, electric, heat, ac, etc and taxes.

Just make sure its a moderate climate as they don't provide tons of heat in cold winters.)3) Not understanding all the ways an appraiser can appraise small multifamily (read: overestimating ARV).

I have a good amount of experience in heating and cooling, especially installs and I know the basics of most other trades outside of carpentry.
