@Paul Reynolds Welcome to BP and congrats on starting your real estate journey!
I always start by looking at the city/town, then dive deeper into the properties themselves.
According to my tool, Rochester, NY looks interesting - crime is decreasing and the levels are good, property values are going up and income is growing strong. My only concern on the city/town itself is the population. I don't like to see an outflow of people.
Now, about the properties themselves. Others have already mentioned this, but neither seem that enticing from an ROI perspective, and your estimates seem a bit low in terms of CAPEX/repairs/maintenance. One of the biggest things to remember when estimating these figures is that some of those costs are "fixed", such as roofs. Of course, the price of a roof isn't fixed in that its always the same price, but the cost of a roof for a 1,500 SQFT house that costs $50k isn't much different than a 1,500 SQFT house that costs $150k, but the former is a much larger percentage of monthly rents, and must be adjusted accordingly.
Hope this helps.
