Brian - I would agree with Bram that there is no checklist when your an investor. It really comes down to finding good deals and no two deals are the same. Nothing is identical and the fact that your own situation is constantly changing depending on where and what your invested into makes it hard to have a checklist that others would find useful. There are so many types of investment opportunities out there it's really finding out what you will be happy with and works for your current situation. For example my most recent investment was finding a multi-unit to house hack and live in for free. I personally wanted my own one bedroom unit to do short term rentals with after I buy and move into my next property but there are also great opportunities out there with multiple bedrooms in each unit. You also need to figure out what your situation will let you do. If you need cashflow your investment is going to be different than if your looking for a long term hold.
I'm an agent in Tucson and we get tons of deals that come through our team. We've never had the issue finding profitable deals for our investors that match their current needs, but ever person has their own checklist to fit their needs so there is no general checklist out there. I'm all about helping people out so if you ever have any questions about investing downtown / UofA area feel free to connect with me.
