If it's a flip, I'd look at the best flips in the closest mile radius sold in the last 6 months.

Denver is a buyer's market - houses sit for a bit (one month plus).

They were perfectly acceptable 20 years ago, but now many areas are limited to one guest per calendar month. 

It took me 13 months to open a bank account in Belize.  

You don't need to know everything to get started; you need a foundation to build on, and the rest will come through experience and then refining your education.You can build a basic understanding of investing in 3-6 months.

If I had an empty unit today, I think it would rent for at least $200/month more than a month ago.  

Income: Verified monthly income must be at least three times the rent (minimum $4,200 combined).

Nice try, but this time does not count.In order to meet 750 hours, your wife will need one of the below:- do something else real estate related, like wholesaling or realtor- actively work on expanding your rental portfolio - have an extensive DIY rehab, like a month-long full-time rehab (and then she might need another kind of rehab)- a calamity such as multiple properties damaged in a storm where she will have to deal with insurers and contractors- something else out of the ordinaryAgain - if all you have is 9 single-family properties with stable tenants and typical occasional maintenance - you don't have enough work to collect 750 hours.

I'll be moving out, and turning it into an investment property in a few months.

Let's say you spent a month on the initial preparation: cleaning, painting, shopping for furnishings, assembling IKEA furniture and so on.
