When defining your primary residence, the IRS would look at facts and circumstances such as: - where you spend the most time- where you get your mail - where you’re registered to vote - the address on your tax returns - the address on your drivers license and vehicle registration Clearly if you rent out both sides of a duplex, it’s not your primary residence.

Best recommendation is speak to a lawyer an have some clearly defined contracts/operating agreements.

CO law states the property has to be remediated before sale, so I'm not sure how you will handle that aspect of it.

The house next door that sold for 225 or 325 won't carry the same intrinsic aspects of value.Often, it's boots on the ground that you need and ones you can trust. 

One huge aspect of analyzing a deal is to make sure you know what market rents are for the area, if not street, you are buying the building in.How do you go about comping your rents and using them for input in your deal analysis?

Your formal letter is an opportunity to define yourself as a professional who knows what they are doing and gives fair, honest, and respectful treatment to all tenants.  

It is a good community to network and learn about all aspects of real-estate investing.

So before you have hustle to go anywhere or do anything, you must have a totally clear, well-defined “who, what, where and how” idea of exactly where you want to get to… or what you want to do.

One disadvantage I see is that it may limit my ability to sell the property to an owner occupant if I have a tenant in place so I can understand that aspect, if I am thinking about this correctly.

I understand completely where you are coming from and i will definately take your info into consideration.
