For CO specifically, are these year-round (Denver metro and Colorado Springs) or resort/seasonal for skiing (understanding Colorado mountain summers are still glorious).

The best thing you can do is to get in touch with a few lenders and walk through your specific scenario. 

Set a specific goal, then work towards it.1.

Consider defining clear roles, ownership percentages, and responsibilities upfront, and ensure you’re protected if the partnership doesn’t work out.Since you already own properties, it might be worth consulting a CPA who specializes in real estate for advice on tax strategies specific to your situation.

If you need financial help, ask under the "Finance, Tax, and Legal" forum.

One question that you may not want to post here for legal reasons, is how much are you paying your PMC?

@Tom OchiengI would reach out to a real estate attorney for specific advice on this situation since you already have one tenant who is being difficult.On a side note, when I have inherited tenants, I have been most successful when I have provided longer non-renewal notices, like 60-90 days, and offered to assist with moving costs.

I understand this is not a requirement, but I have never received a damaged unit from an inherited tenant or any legal issues.

In terms of renovations it really doesn't matter much from a tax perspective.The bigger question is what are your specific investment goals?

Have to agree with most here in that a SF-> duplex conversion needs some really specific qualities to be worth the squeeze.
