@Rob MacSwan - You have some good advice on here. Someone took a look at the local comps (kudos to @Ronald Martin) and made a good point that your estimated repairs may be low.
Out of curiosity, where did you come up with the $2000 repair and improvement? Will you be doing the work yourself? What all were you including in this (paint and general cleanup?)? For an older home, $2000 might be low unless if it only needed some lipstick. What is the age of the roof, water heater, furnace, etc?
It looks like you used roughly 10% for maintenance, repairs, and CapEx (guessing that's where the $330/month came from) - if so, you're on the right track for estimating expenses. The only thing missing is vacancy.
I would strongly suggest taking another look at the age of the property and determine whether you should increase the percentage for maintenance and CapEx if you expect any of the big ticket items to wear out in the near future (5 years or less).
What I would do:
Determine age of the home and have an inspection done if you aren't experienced. From that, get an estimate on how much repairs and improvements will cost.
Determine how much CapEx and maintenance you should set aside per month (percentage of income). 10% is a good starting point for each, but consider increasing that percentage based on the age of the property.
Find out how much rent will be. I use RentOMeter or RentJungle to find these numbers.
Decide how much cash flow you want to see
Back-calculate the purchase price based on the above data. Maintenance, CapEx, taxes, insurance - these are all "set" values that you shouldn't play with in order to "create" income. Yes, you can increase cash flow by decreasing CapEx savings. Don't do it. Instead, you can increase cash flow by decreasing your financing payments - decrease the purchase price, find a lower interest rate, etc.
Unless if there are major issues with the inspection, this could be a good property to purchase. You'll have to do a little legwork to decide what the purchase price is.
